Guardian Angles: Forced Sex to Pay Hospital Bills?

Chatham House has published a paper entitled 'Hospital Detentions for Non-payment of Fees: A Denial of Rights and Dignity', the title being a good indication of what the article is about, and why a leading think-tank concerned with international affairs would research and report on such an issue.

The practice of detaining patients in the grounds of a hospital until they pay their bills, with costs continuing to rise to cover their period of detention, is widespread in developing countries. Many people in those countries see it is unremarkable, even though it infringes on the rights and threatens the health of the poorest and most vulnerable.

Relatively little research has been carried out, so the above paper suggests that its findings represent only a fraction of the severity and breath of the issue. But people can be subjected to all kinds of abuse while being held, aside from the abuse of being detained in appalling conditions.

They can be denied vital health services, forced to live in inhumane and uninhabitable surroundings, subjected to physical, verbal and emotional abuse, without access to assistance or advice, without even the realization that healthcare establishments do not have the right to detain them in the first place.

However, the details given in the Chatham House report do not justify the headline 'Women in sub-Saharan Africa forced into sex to pay hospital bills'. The report does list an allegation that patients have "been pressured into having sex with hospital staff in exchange for cash to help pay their bills", also an allegation about "baby-trafficking".

The Chatham House report links to what sounds like a very tenuous source for some of its findings, but they also refer to such items as 'allegations', as distinct from better supported findings.

The newspaper article also cites several questionable assertions, including one about women having sex with 'doctors' for a few dollars to pay off bills that amounted to thousands of dollars, but without flagging up the potentially low credibility of the source.

The newspaper article fits into a pattern of tabloid-style articles citing sources that ostensibly support their title and following assertions; yet, when you look at their sources, these turn out to give little or no support whatsoever. It's as if the article was published because it could say what the editor wanted to publish, rather than report what the journalist found.

For example, an earlier article from the same newspaper about giving aid in the form of cash transfers is written as if this was found to be one of the most effective ways of providing assistance, but citing a report that came to the opposite conclusion.

The author of the hospital detentions article recently wrote about HIV in the Himalayas, saying that she found that it was all the fault of the men, and that the women just had to put up with it. The men were 'migrant workers', who 'lied' about how they could have been exposed to HIV, and the woman remained silent, we are told.

And another article in that newspaper blames a rise in HIV transmission on 'dating apps', because 'every app is a dating app', according to the title. Perhaps this is an instance of what the New York Times refers to as 'techno-moral' panic, which can take anything currently fashionable, 'cyberporn' in the 90s, chat-rooms not long after that, sexting, online predators, etc, and vent their indignation.

Remarkably, the article about dating apps purported to be about HIV in Pakistan, which is in the lowest quintile for HIV prevalence, globally. Although newspapers cling to the view that HIV is almost always a result of 'unsafe' sex, in Pakistan (and most other countries) there is ample evidence that there have been outbreaks caused by unsafe healthcare in some of the highest prevalence areas, as well as in some low prevalence countries (Pakistan, Cambodia, etc).

These journalist are happy to wallow in their favorite fantasies about ‘African’ sexual behavior, dating apps, transactional sex, trafficking and the like, almost as if they have to make up the story before an even less reliable source does so.

At the same time, they distract attention from much more serious, but far less media friendly issues, without contributing anything to the problems that they claim to be drawing attention to in the first place, at least by highlighting topics that have been missed so far, but are in serious need of attention.

‘African’ Sexuality: Colonial Trope or New Racism?

An article entitled ‘Colonial tropes and HIV/AIDS in Africa: sex, disease and race’ discusses the “idea of Africa as a place where health and general well-being are determined by culturally (and to a degree racially) dictated modes of sexual behaviour that fall well outside of the ‘ordinary’”. It raises some welcome questions about the claim that HIV is almost all caused by heterosexual behavior, but only in ‘Africa’.

The authors continue: “By analysing historical responses to these two pandemics [syphilis and other STIs on the one hand and HIV on the other], we demonstrate an arguably unbroken outsider perception of African sexuality, based largely on colonial-era tropes, that portrays African people as over-sexed, uncontrolled in their appetites, promiscuous, impervious to risk and thus agents of their own misfortune.”

This blog, and a small number of people writing about HIV in African countries, share Flint and Hewett’s disgust for “the promulgation of the European idea of African men as over-sexed and, by implication, predatory and dangerous and African women as over-sexed, promiscuous and shameless”. But the HIV bigwigs do not apologize for institutionalizing such prejudices, and never have.

While Thabo Mbeki was disingenuous to claim that HIV does not cause AIDS, Flint and Hewitt support his claim that “the outsider view of Africans remains one of people who are ‘diseased, corrupt, violent, amoral [and] sexually depraved’”. The HIV industry has a tendency to brand anything they see as questioning their rigid stance as ‘denialist’. Mbeki’s questions remain unanswered, perhaps unanswerable, by an industry that refuses to apply scientific methods in a region where the overwhelming majority of HIV positive people live.

Flint and Hewitt continue: “HIV/AIDS discourse can be seen to have slotted into an existing colonial narrative of the mysterious, unknowable and, above all, different, that was primed to accept the notion of HIV/AIDS in sub-Saharan Africa as a ‘disease of choice’ (with corresponding notions as to combating this perceived choice) – in remarkable contrast to ideas as to HIV/AIDS epidemiology and prevention outside the continent” [my emphasis].

The industry had to tone down their notions of ‘good AIDS/bad AIDS’ in western countries; fashions change (or 'are changed'). But it was (almost) all ‘bad AIDS’ in ‘African’ countries, all someone’s own fault, all ‘avoidable’, if people would just follow advice to abstain, be faithful, avoid ‘traditional’ practices, embrace western style healthcare (albeit without western standards of safety, hygiene, funding or staffing).

The attitude towards HIV in ‘African’ countries was especially reinforced by massive sources of funding, such as PEPFAR, “a programme influenced by and largely delegated to faith-based organisations, which engendered it, at times, with something of a crusading missionary outlook. Its emphasis on abstinence and fidelity suggested strongly that each person was broadly responsible for their own individual ‘salvation’: to be infected with HIV implied moral slippage”.

Flint and Hewitt have squeezed a lot into a paper that covers so many issues, spread over a long period. However, I think they have neglected a few things that might have altered their conclusion, considerably. Firstly, they mention (in a footnote) David Gisselquist’s contention that the HIV pandemic could not have been caused by sexual behavior alone, and that unsafe healthcare practices might explain a significant proportion, perhaps even a larger proportion than sexual behavior.

With the realization that the pandemic could not have been caused entirely by ‘African’ sexual behavior, isn’t there an immediate and urgent question about what else may have been involved? Reference is made to the preponderance of epidemiologists and other interested parties with their snouts in the trough, but the sheer weakness of the evidence for this assumed ‘African’ sexual behavior must also be examined. Epidemiologists have made it clear that they are certainly not going to revise their views and consider unsafe healthcare, or anything else.

Secondly, I would also question Flint and Hewett’s claim that the line running from colonial bigotry about sexual behavior in Africa to today’s HIV industry’s institutionalized racist narrative of the HIV pandemic is ‘unbroken’ (and they do say ‘arguably’). The vitriolic hatred shown by people writing about sexually transmitted infections, ‘African’ sexuality and many other subjects was clear enough in the late 19th and early 20th centuries, continuing up to WWII, at least. But, I would argue, things changed.

There was a phase of gradual enlightenment among writers of medical papers in the three or four decades preceding the identification of HIV as the virus responsible for AIDS. Flint and Hewitt even cite an early paper from one of those whose views were based on his own research in African countries, Richard Robert Willcox [obituary]; and there were others who brought greater humanity to ‘colonial’ medicine, which had previously been viewed as just another instrument of control. One example from Willcox will have to suffice for now.

Far from blaming STIs entirely on those who contracted them and transmitted them, Willcox and some of his contemporaries wrote that there are promiscuous people everywhere, and that STIs are mainly found among promiscuous people. But they also made it clear that the majority of people are not promiscuous; several of them might even have admitted that people in Africa were no more likely to be promiscuous than people elsewhere, which is anathema to the HIV industry.

Thirdly, Flint and Hewitt don’t mention that many earlier estimates of diseases, assumed to be sexually transmitted, were distorted by the inability to distinguish non-sexually transmitted yaws and other diseases from syphilis. Figures purporting to show massive levels of endemic syphilis were not just exaggerated by the eugenicists, they were also empirically incorrect. Willcox knew that, as did many of his contemporaries.

Outbreaks of STIs could also be explained by poor treatment programs, insanitary living conditions, labor conditions (especially in mines, armies, etc), resistance to medication, shortages in supplies, unsafe conditions in healthcare facilities, changes in epidemic patterns, lack of skills among personnel involved, shortages of skilled personnel, etc. Outbreaks of HIV could also be explained by such factors, if only more epidemiologists would accept that there is no disease that has a single cause, a cause entirely isolated from all other determinants of health, and that this unprecedented circumstance can only be found in certain African countries (a fifth of 'Africans' live in a region where HIV positive people make up 0.06% of the population).

Numerous factors involved in STI epidemics, only a some of which are mentioned above, were recognized by many pre-HIV era writers. Therefore, those blaming disease outbreaks on ‘promiscuity’ and other ‘African’ behaviors, were bigots, not badly informed commentators. Some time after WWII, ‘colonial’ views about ‘African’ sexual behavior, at least in medical literature, became less common. It took a few decades, of course. But by the 1980s, when AIDS was recognized as a syndrome and HIV was identified as the cause, unbigoted views were frequently expressed about STIs and ‘Africans’.

The extreme views of today’s HIV industry are not, I would argue, a clear continuation of colonial bigotry. Following three to four decades of increasing scientific rigor (and decreasing institutional racism), the emerging HIV industry of the 1980s had to develop its own form of racism. Many of the earliest proponents had little or no connection with the colonial past, although they adopted several of its more egregious ‘tropes’, being compatible with some of the extreme political and social attitudes also emerging at the time.

It's the Truth, Bill, But Not as We Know It

"Aid given in cash improves health and spurs school attendance, say researchers", according to a title in the English Guardian. "Foreign aid in the form of cash transfers with no strings attached can improve health and increase school attendance, a study has found", claims the article. Yet, the conclusion of the study is "The evidence on the relative effectiveness of UCTs [unconditional cash transfers] and CCTs [conditional cash transfers] remains very uncertain".

The author, Hannah Summers, has been mentioned in a blog post here on the subject of racism, HIV and pathologizing sex, and then in a double take on the same set of issues. On the subject of cash transfers, she writes as if her job, or her newspaper's future, depend on spinning this hyped strategy, which has been claimed to reduce poverty, influence behavior, improve health, and just about everything desirable you can think of.

No mention is made in the Guardian about quality of evidence gathered by the study, which, in this instance, is astonishing: "Of the seven prioritised primary outcomes, the body of evidence for one outcome was of moderate quality, for three outcomes of low quality, for two outcomes of very low quality, and for one outcome, there was no evidence at all."

This is not to say that handing out money to poor people had no discernable benefits. People with more money can, and often do increase spending on things like food, medicine, education, living conditions and a better environment (if cash transfers were ever to reach such dizzy heights).

So it is no big surprise that people with more money, spending more on the above, will have fewer illnesses, improved food security, and perhaps dietary diversity, school attendance, etc. Nor is it a surprise that these improvements can lead to other improvements, given time and persistence.

But is it necessary to carry out 21 studies, involving over a million participants and over 30,000 households to know that poor people need money, and that having more money will have health, education, social, environmental and other benefits?

Is Summers entitled to claim that: "a review published this week flies in the face of criticism from the anti-aid brigade, showing that cash handouts have measurable benefits for some of the world’s poorest people." Is someone ‘anti-aid’ because they question her spin on this charade?

At times, cash transfers look like a form of pimping. International NGOs and other recipients of funding for cash transfers take a big slice for themselves. Academics get grants for the inevitable studies, some consultants and experts depend on this kind of work for much of their (considerable) income, lots of well paid people are well paid by these 'initiatives'.

Just in case the similarity to pimping is not clear, cash transfers have been used to induce people, mainly women and girls, to have less sex, to only engage in protected sex, to go to school (said to reduce sex, or ‘unsafe’ sex), etc. If paying for sex is, at least in part, an attempt to control a woman's sexual or reproductive choices, then so is paying for chastity.

If aid programs in their current forms are working, and need to be expanded, particularly certain types of aid program, why lie about the findings of a systematic review that explicitly questions conditional and unconditional cash transfers, and why would the English Guardian publish this obvious perversion of the findings of a Cochrane Review?

The Story is Father to the Author

The story of 'How HIV found its way to a remote corner of the Himalayas', is related in an article in the English Guardian. It was male economic migrants who went to India and "returned home with a very different legacy to the one [they] anticipated", infecting their partners, who then had children born with the virus. (But things are now improving because of the actions of the female victims.)

Here's a comment on an 'interview' with one of the males who went to India to work: "Like many other men interviewed in Achham, Sarpa has a well-rehearsed story that explains how he believes he contracted HIV, but it does not involve any sex workers, whom researchers believe are the primary source of migrants’ HIV infections."

Journalist Kate Hodal doesn't bother telling us how Sarpa says he was infected, preferring instead to believe the testimony of 'researchers'. How these researchers know that Sarpa is a liar, along with all the other people they have interviewed (and disbelieved), is anyone's guess. Perhaps they have some independent explanation or account of the HIV risks that people face in India?

While Sarpa speaks "coolly", his wife Sita "has had to accept the likelihood [Sarpa] visited Indian brothels", indicating all this with a shake of her head.

Hodal is clearly something of a psychic, who can know that while Sarpa lies, Sita tells the truth, but without uttering it. Hodal also knows that the opinion of researchers about HIV risks is of more value than the self-reported accounts of people who are infected, or who may become infected.

Meanwhile in Canada, journalist Ashifa Kassam writes about a pop-up restaurant run by HIV positive people. Far from pointing the finger at people with HIV, the article is about ‘challenging stigma’. The words of those interviewed are quoted, and their honesty is not in question.

Population figures, numbers of people living with HIV, prevalence, even the breakdown by gender of those infected, are not vastly different in Canada and Nepal. Although Nepal’s epidemic is usually described as ‘concentrated’, in contrast to Canada’s ‘low-level’ epidemic, the two are remarkably similar in some ways.

In contrast, in Canada, the vast majority of people are infected with HIV through unprotected, receptive anal sex and injecting drug use. But neither of those routes are thought to be so common in Nepal.

However, there is a huge difference in the way HIV in Nepal and Canada are viewed by the media. In Canada, those with HIV are wholeheartedly encouraged to continue their fight against stigma. But in Nepal, the journalist writes something she may have believed before she left her desk: HIV is ‘spread’ by promiscuous men, to unwitting women and children.

HIV positive Canadians can speak for themselves, and are not required to explain or justify their status. But Nepalese men need journalists and researchers to call them out on their lies about how they were infected; and Nepalese women need the same intermediaries to identify them as victims, unable to name the aggressors, or to speculate about how their partners became infected.

HIV and Sex: Fallacy of the Single Cause

The four Kenyan counties of Kisumu, Homa Bay, Siaya and Migori that I mentioned in my last blog post have been in the news following the rerun of the presidential elections on Thursday 26 October. Voting in these four counties was suspended at an early stage and scheduled to resume on Saturday 28, but they did not go ahead.

The result of the presidential elections held in August was disputed in court, hence the rerun. But the opposition leader, Raila Odinga, later called for the elections to be boycotted, and turnout has been very low. The four counties in question are home to the majority of Odinga’s own Luo tribe, and a large proportion of people who might vote for him as president.

Astoundingly, one third of all of Kenya’s 1.6m HIV positive people live in these four counties, even though only about one tenth of Kenyans live there. These counties make up the bulk of the former Nyanza Province, in the southeast. In the blog post before that I wrote about a contrasting area, where 0.2% of HIV positive people live: Mandera, Garissa and Wajir, the former northwestern province, with a population of about 1.6m (3.5% of Kenya’s population).

In the earlier of these two posts I speculated that HIV prevalence in the northeastern counties may have remained low because of the geographical isolation of the area. Few roads go there, infrastructure is underdeveloped, health services are few and far between, and usage of health services tends to be low. Quality of health services is also likely to be low, but less harm can result if most people stay away from facilities.

In the southwest, where infrastructure is a bit better, usage of health services is higher. This means that a lot more people are being exposed to potentially unsafe healthcare. Over 4m people live in 10,200 km2, compared to the 1.6m people in the northeast, an area of 127,300 km2. Population density can be lower than 10/km2 in the northeast and as high as 460/km2 in the southwest.

Variations in sexual behavior don’t correlate very well with variations in HIV prevalence or distribution, so it can’t be the single or simple cause of HIV transmission. UNAIDS and other establishments involved in HIV programming claim that 80-90% of HIV transmission in high prevalence African countries is due to ‘unsafe’ sexual behavior, but they have never been able to demonstrate how such a claim could be true, or even plausible.

However, it could be argued that variation in exposure to potentially unsafe healthcare practices correlates much better with HIV transmission. Both areas are isolated politically, and have been for many decades. Low usage of health facilities and social services (and low availability) seems to be a consequence of the political isolation experienced by the northwest. It is home to many of Kenya’s ethnic Somalis, a piece of land that was formerly part of Somalia.

Down in the southwest, the politically isolated Luo population experienced a certain amount of growth and prosperity after independence, especially during the explosion in the population of Nile Perch in Lake Victoria. People with a bit more money are likely to spend some of that money on healthcare. But if that healthcare is not of high quality, is not safe, this might explain why wealthier people in high prevalence African countries tend to be more likely to be infected with HIV than poorer people.

These two geographical areas have certain things in common: they are overwhelmingly populated by one ethnic group, and have both sought to distance themselves from the rest of Kenya; there has even been talk of complete political separation. But there must also be something very different about the two areas that explains why the HIV burden is over 160 times higher in the southwest than it is in the northeast.

Search for ‘sexual reductionism’ on Google and you’ll come across a discussion about a Vermeer exhibition at the New York Metropolitan Museum of Art. This will give you some idea of how current HIV epidemiology seems to proceed. Apparently the texts accompanying the paintings treat every detail of the art works as being about sex.

For UNAIDS, variation in HIV prevalence is all about sex: poor people sell sex, rich people buy sex, as do employed people, women are more vulnerable to sexual exposure than men, men are more promiscuous, sexual mores are different in Muslim communities, etc. But an alternative explanation is that variation in access to potentially unsafe healthcare facilities can better account for variation in HIV prevalence within and between geographical areas.

The history of the isolation of the southwest and northeast counties of Kenya from much of the rest of the country, political, geographical, ethnic and other forms of separation, is a long and complex one. But so too is the history of the HIV epidemic, from its origins in equatorial Africa to its global spread, and the multiple causal factors that resulted in hyperendemic levels in some countries (and within some countries), but low levels in others.

Via Negativa and ‘First do no Harm’

I am in favor of routine vaccination, for my children and for children in my care. I always take children to a doctor when there is something that won’t go away on its own, or that I don’t recognize, and I would do the same for myself. So I am certainly not advocating ‘doing nothing’ as a response to medical problems. I write as a layperson, with an interest in healthcare and development.

But all healthcare must also be safe healthcare; people should be granted their right to know everything they need to know in order to make the best choices for themselves and their dependents, in accordance with the Lisbon Declaration on the Rights of the Patient, along with other instruments relating to patient safety. I feel that people, especially in developing countries, are frequently denied these rights, and that the results of this can be fatal.

In his guest post for this blog, Helmut Jager discusses the example of the infection of millions of Egyptians with hepatitis C (HCV) through unsafe healthcare, resulting in the highest prevalence of the virus in the world. Jager states that the “causes of the infections [globally] mostly are: bad medicine or intravenous drug addiction”.

The ‘bad’ medicine Jager refers to is a program intended to reduce infection with schistosomiasis (bilharzia), caused by a waterborne parasite. This program involved the use of syringes, needles and perhaps other equipment that were not always sterile. Under such conditions bloodborne pathogens, in this case, HCV, can be transmitted from patient to patient.

The medicine Jager describes is ‘bad’ because conditions in healthcare facilities are unsafe, instruments are being reused without adequate sterilization, etc. Rising numbers of people with HCV in the population eventually visiting health facilities meant increasing numbers of healthcare associated transmissions, also called ‘iatrogenic’; a vicious cycle.

Jager is not suggesting that healthcare facilities should do nothing about schistosomiasis (or any other condition) in order to avoid the risk of iatrogenic transmission of HCV or other bloodborne pathogens. He is recommending that unsafe practices be eradicated, practices such as the reuse of injecting and other equipment and processes that involve piercing the skin, or even come in contact with bodily fluids, such as speculums, gloves, etc.

Reducing unnecessary medicine is another of Jager's recommendations. The WHO estimates that 16 billion injections are administered globally every year. In some countries up to 70% are probably unnecessary. About 37% were said to involve reused injecting equipment. Therefore, reuse of other skin-piercing equipment may also add substantially to the problem.

Jager’s blog is about the high cost of Gilead’s ‘sofosbuvir’ and the damage this does to programs aimed at eradicating the virus. Sofosbuvir has been recommended by the WHO for the treatment of HCV: it is unaffordable for people in poor countries, who make up the bulk of those living with the virus, at risk of suffering serious illness from it, and of dying from it. Jager cites a source reporting that “treatment costs in the US are US$84,000 and in the Netherlands €46,000. The production cost of the drug is estimated not to exceed US$140.”

There are two man-made disasters here: first, there’s the raising of the Aswan Dam in the 1960s. The dam was intended to control the flow of the Nile in order to improve irrigation provision and generate hydroelectricity; this damaged ecosystems and led to an increase in schistosoma infestations. The second was the massive outbreak of HCV caused by unsafe healthcare procedures, employed to address the schistosomiasis endemicity, that affected millions of people.

Apparently environmental impact assessments evolved in the 1960s, but it is likely there was something similar before the specific phrase was adopted. After all, it was known that introducing invasive species of fish to Lake Victoria would cause huge and irreversible problems early in the last century; the invasive species were introduced anyway, because certain parties wanted them to be (the colonials wanted to introduce sport fishing to the lake for their enjoyment). The fragility of ecologies has been recognized for a long time.

Whether either or both these disasters could have been avoided 50 or more years ago, strategies to eradicate schistosomiasis sometimes seem to concentrate on a quick technical fix (there’s even a vaccine in development now), such as mass administration of Praziquantel. Praziquantel works, up to a point. It cures patients, and reduces the infected population, which promotes herd immunity and helps interrupt the life cycle of the parasite. But it is less effective in eradicating the parasite when used on its own.

Research in Lake Victoria finds that the population affected by schistosomiasis also needs access to safe drinking and domestic water supplies, reduced contact with contaminated water, adequate waste disposal (which can interrupt the life cycle of the parasite), etc. In other words, the first disaster Jager alludes to, schistosoma infestation in the waterways, affects a much larger population than those who live close to and depend on the waters of the Nile.

This is a larger and more general problem, because all massive infrastructure projects risk destroying ecosystems and environments. And the medical treatment people need once their water supply is infested can be too little; but possibly not too late. It’s too little because those affected will still need access to safe water and sanitation, but some of these issues can be addressed, bearing in mind the counsel of ‘first, do no harm’.

Water and sanitation provision is vital, as is promotion of good health related information. Gilead are unlikely to scale back their profits much unless they are compelled to do so; yet, intervention would not be unprecedented. Unsafe healthcare can be eradicated, much more cheaply and efficiently than mopping up the victims of unsafe healthcare. And unnecessary healthcare can also be reduced, substantially, which will also reduce unsafe healthcare.

In my previous post I speculated that counties in Kenya with very low HIV prevalence, such as Wajir, Garissa and Mandera, may have escaped high levels of transmission through unsafe healthcare by having very low levels of healthcare provision of any kind. I also speculated that high HIV prevalence in counties such as Homa Bay, Kisumu, Siaya and Mogori may be a result of greater access to healthcare facilities and health programs whose practices are not particularly safe.

So those four counties on the shores of Lake Victoria, with fishing as one of the most important activities, must have very high rates of intestinal parasites (and other conditions). If use of health facilities is high, the chances of a pathogen such as HIV contaminating medical equipment, which is then reused without adequate sterilization, must also be high.

Where healthcare is unsafe, carrying the risk of exposure to bloodborne pathogens, such as HCV, HIV and others through reuse of skin-piercing instruments, it’s best avoided; via negativa is the best counsel, even if most avoidance is a result of poverty now. There is still the option of ‘doing no harm’, but only if the contribution of unsafe healthcare to HIV epidemics so far is thoroughly investigated. If that's not done, people would be better off to stay away from healthcare facilities.

Via Negativa: the way to low HIV prevalence?

Wajir is a city and county in Kenya’s former North Eastern Province. From a HIV perspective, the county stands out for having the lowest prevalence of all Kenya’s 47 counties, currently estimated at 0.4%. The next highest counties are Mandera (0.8%) and Garissa (0.9%). Wajir, Mandera and Garissa make up what was the province, formerly a part of Jubaland, in Southern Somalia.

Homa Bay is a town and county in the south west, formerly part of Nyanza Province, and the number one county for HIV prevalence, 26%. Indeed, the only counties with prevalence above 10% are Siaya, Kisumu (19.9%), Migori (14.3%) and Homa Bay, which (along with Kisii and Nyamira) made up Nyanza. That accounts for one third of all HIV positive people in Kenya.

The question of why HIV prevalence is so high in certain parts of Kenya is usually answered, implicitly or explicitly, with half baked notions about ‘African’ sexual behavior, ‘African’ mores, ‘traditions’, sexual practices, ‘unsafe’ sex, promiscuity. In a word: sex. It’s all about sex, and in the worst hit counties experts have persuaded the US to part with hundreds of millions of dollars for mass male circumcision programs.

A lot less seems to be written about the extremely low HIV prevalence found in the north east. Look up Mandera, Garissa or Wajir on PubMed and you will only come across just over 300 papers altogether, compared to thousands for other locations (and almost 50,000 for Kenya as a whole). But it would be interesting to know how HIV prevalence has remained as low as in many western countries in the north west of Kenya, yet it has risen as high as the worst hit countries in southern Africa in the south west of Kenya.

Sex happens in north eastern counties too. In fact, condom use is generally lower in these counties. Polygamy is more common, as are intergenerational sex and marriage, phenomena the HIV industry sometimes insists are risks for HIV transmission. Knowledge about HIV transmission and how to avoid it tends to be lower in these counties, too. Birth rates are higher than in other parts of the country.

Circumcision is said to be widespread in a number of counties, not just in Wajir (and Mandera and Garissa) but also, for example, in Kilifi. But HIV prevalence in Kilifi is a lot higher, at 4.5%. The populations are predominantly Muslim in both counties, so circumcision is not likely to be the full explanation, nor is religion. There are commercial sex workers and men who have sex with men in every county, with no evidence that these practices are less common in low prevalence counties.

The north eastern counties are, in fact, very different from the rest of Kenya. Kenya was divided up on ethnic lines by the British, which is why the territory once called the ‘Northern Frontier District’ became one province: it was, and still is, populated by ethnic Somalis. They are geographically isolated, in the sense that there are few major roads. Much of the north of Kenya is arid and sparsely populated. Even the Somalis who live elsewhere in Kenya, such as in Nairobi, tend to live in predominantly Somali suburbs.

A similar kind of isolation, albeit on a much larger scale, can be found in northern Africa. The Sahara is sparsely populated and there are few major roads traversing it. HIV prevalence is low in all North African countries. In fact, HIV arrived relatively late in North Africa, and analysis of the common subtypes there suggest that the epidemic spread to a large extent from southern Europe, and to a lesser extent from West and central Africa.

The most common HIV subtype in Kenya is type A, followed by D, with a small proportion of type C. But the most common subtype in the north east of Kenya is type C, this being the most common subtype in southern Africa, Ethiopia and a number of other countries. So the former province really does seem to have a different epidemic or ‘subepidemic’. Type C is known to have evolved later than A and D, so the former North Eastern Province’s subepidemic is newer, like those in North African countries.

But it is still unclear how the above features of certain epidemics and subepidemics are associated with very low prevalence. Instead of looking for phenomena behind very high prevalence in some south western counties, are there certain phenomena that are absent in the north west (and in North Africa)? Isolation doesn’t mean less sex, nor even less ‘unsafe’ sex, and sexual behavior is very poorly correlated with HIV transmission.

We don’t know much about Wajir, Mandera and Garissa because not much research has been carried out there, and it’s not surprising that little HIV research has been carried out where there's little HIV transmission. But what about other healthcare research? I notice almost all the articles on PubMed are about HIV, and were published in the last 20-30 years. So the area has been isolated from research for a long time.

Now, if there are few roads and limited infrastructures, is healthcare infrastructure similarly limited? It could be expected that access to healthcare facilities is poor and that many people rarely or never go to a hospital, or see any kind of health professional. The majority of women probably give birth at home, coverage of mass drug administration programs, including routine immunizations, is probably lower for these and other more isolated counties.

Borrowing Nicholas Nassim Taleb’s ‘via negativa’ in his book ‘Antifragile’, perhaps HIV prevalence in the north east of Kenya (and in North Africa) has remained low because of infrequent contact with healthcare facilities. This is not to say that healthcare facilities are unsafe in the north east, although it does suggest that they are unsafe in high prevalence counties. Also, it is suggested that HIV is circulating in health facilities, more in some than in others.

Many (including Taleb) like to repeat that ‘absence of evidence is not evidence of absence’. There is a possibility that HIV has been, and is still circulating in health facilities in Kenya, and may account for a significant proportion of infections, perhaps the majority of infections. Little research has been carried out to estimate the relative contribution of healthcare associated HIV transmission. We will never know until the evidence is sought: does limited contact with healthcare keep HIV prevalence low in the north east of Kenya?

UNAIDS: Still Spanking the Chimp

How are we to make sense of a HIV epidemic such as the one in Uganda? We are told that it is mostly a result of ‘unsafe’ sex. But data about sexual behavior in Uganda is unremarkable; most people don’t engage in high levels of unsafe sex, and types of sexual behavior considered unsafe appear not to be so unsafe after all.

In 2007, it was estimated that there were almost one million people living with HIV, 135,000 newly infected with HIV in that year, and 77,000 deaths from Aids. The Demographic and Health Survey for Uganda in 2011 concluded that “Differences in HIV infection according to higher risk sexual activity are minor”.

In fact, the vast majority of the 18,000 people surveyed did not engage in sexual behavior considered to be risky. Most people had a maximum of one partner in the last 12 months, most who had more than one partner did not have concurrent (overlapping) partnerships, most did not report large numbers of lifetime partners, most didn’t pay for sex and most didn’t engage in ‘higher risk’ sex in the past 12 months.

So it’s hard to believe that the table appearing on page 15 of the Modes of Transmission Survey (MoT) for Uganda, for 2009, can be anything but fiction. It claims that almost 90% of HIV incidence is a result of multiple partnerships, partners of multiple partnerships and people engaged in mutually monogamous heterosexual relationships.

Even incidence attributed to sex workers doesn’t reach 1%, nor does that attributed to men who have sex with men, plus their female partners. Injecting drug use doesn’t play a big part in most of the epidemics in sub-Saharan Africa either.

The DHS figures for Uganda clearly do not support the MoT figures. They do not support the contention that high HIV prevalence indicates high rates of ‘unsafe’ sexual activity; HIV prevalence is high in Uganda, but sexual activity is not exceptional, nor is it closely associated with HIV transmission.

DHS continues: “HIV prevalence by the number of sexual partners in the 12 months before the survey does not show the expected patterns”. It is noted that “HIV prevalence shows the expected relationship with the number of lifetime sexual partners” but the author doesn’t mention that the numbers of people involved is very small. So they conclude that “it is important to remember that responses about sexual risk behaviours may be subject to reporting bias”.

Uganda was one of the first countries to expose itself to the scrutiny of the rapidly developing HIV industry, from the 1980s. As a result, a lot more studies took place there, a lot more papers were published about Uganda and tens of millions more dollars were spent there than in any other African country, even countries that later turned out to have far worse epidemics.

It takes more than a bit of fluffing to get from the Demographic and Health Survey’s flaccid data on sexual behavior to the conclusion that almost 90% of HIV transmission is a result of unsafe heterosexual sex. But if the industry doesn’t come clean about where the bulk of new infections are coming from, resources targeted at those thought to or claimed to engage in ‘unsafe’ sex will continue to be wasted.

HIV: A Rich Seam in a Long Abandoned Mine?

Here's a stomach-churning quote from The Eugenics Review, 1932: "East Africa [has] a heavily syphilized native population", where tests suggest that "not less than 60 per cent. to 70 per cent. of the general native population" have some kind of sexually transmitted disease.

At that time, several conditions were mistaken for syphilis (or other STIs). For example, yaws and endemic syphilis, neither of which are sexually transmitted. Prejudices about 'African' sexual behavior were used to prop up beliefs about prevalence of STIs (and prejudices about STIs proped up beliefs about sexual behavior).

You might think that things would have moved on a bit, what with eugenics no longer having the cache it had in the thirties, right? But the received view of HIV in high prevalence countries is that 80-90% of transmission is a result of sexual behavior, mostly heterosexual behavior.

From this 'expert’ opinion about ‘Africa’, it is assumed that high HIV prevalence indicates high rates of 'unsafe' sexual behavior, and that high rates of 'unsafe' sexual behavior (or rates that are assumed to be high) indicates high HIV prevalence, or that prevalence will reach high levels in the foreseeable. It’s pretty easy to spot the pig-headed circularity in the argument.

So, how far have we moved on 80 years after the Eugenics Review quote, above? Here’s Catherine Hankins, from the Amsterdam Institute for Global Health and Development (formerly a senior officer in UNAIDS):
As Hankins surmises, in some cultures what you do with your sexual partners over time is different. In the West we tend to be serially monogamous.
In Africa, if you've had sex with someone at some point, the door isn't considered closed on picking up on that relationship again.
"Take a middle-class African businessman. He has had five women - nothing excessive. But the pattern we find is that he has a wife. He also has an on-off affair with an office colleague. He also has what the French call a 'deuxième bureau' - a mistress who might have a child. And once a year he goes back to his home village and has sex with his original village sweetheart. Then he gets HIV from a bar girl on a business trip.
"Within a year he may have infected four other women. Now, if I've had five sexual partners and catch HIV from the fifth, as a western woman I'm unlikely to return to the other four and infect them!"
You might object that it is unfair to criticize what is clearly just an opinion, however ‘expert’. But policy is based on such opinions, HIV programs are guided by them, enormous amounts of money are spent (entirely in vain) on them. Worse still, the scientific data so assiduously collected shows that Hankins is as wrong as the eugenicists. Ostensibly, at least, Hankins was responding to scientific findings, published in a scientific journal, not to someone's opinion.

You can look through any Demographic and Health Survey you like, where you will find numerous tables about sexual behavior, family life, people’s ability to recall selective tidbits about HIV, etc, but you will not find a country where a large number of people have lots of sexual partners, or engage in sexual activities considered to be unsafe.

In addition, the circularity mentioned above comes across very clearly in Hankins’ invective: HIV prevalence is high because rates of ‘unsafe’ sexual behavior are high, and we know about sexual behavior because HIV prevalence is high. Hankins clearly believes all these prejudices that she expresses about sexual behavior among ‘Africans’!

Three countries account for about one third of all HIV positive people, globally; South Africa (6.8m), Nigeria (3.2m) and India (2m). The same three countries also accounted for more than half of all aids-related deaths in the past few years. It is notable that prevalence is low in India, at less than 0.3%. This compares to about 3% prevalence in Nigeria, and about 19% in South Africa, more than 60 times higher than in India (and it can rise to well over 100 times higher in certain demographics).

Whatever is behind the huge rates of HIV transmission in these countries, which tend to be concentrated in certain geographical areas and populations, it is likely to be something that is amenable to scrutiny, whether it involves the copious quantities of sex that UNAIDS would claim, or something else, for example, dangerously low standards of hygiene and infection control in some health facilities.

Hankins seems intent on mimicking the media approach to HIV, concentrating on relatively rare and infrequent phenomena (deliberate transmission, ‘virgin cures’, fake healers, ‘traditional’ practices, etc), but failing to notice the appalling conditions in healthcare in some of the areas worst hit by HIV. What is it that is deflecting attention from everyday phenomena, allowing such extreme views to prevail, but failing to reduce infections in the worst hit areas?

Pre-Exposure Prophylaxis: Risks in the Pipeline?

An estimated 1 million Kenyans are receiving antiretroviral drugs, about 64% of all HIV positive people. Partly as a result of this, death rates, along with the rate of new infections, have continued a decline that started in the early 2000s, and the early to mid 90s, respectively. Now pre-exposure prophylaxis (PrEP) is being added to the country’s HIV strategy, a course of antiretroviral drugs taken by HIV negative people, which should significantly reduce the risk of their being infected.

So this should be a good time to look at how HIV treatment in its various forms should be targeted. ARVs are relatively straightforward, people testing positive can be put on treatment. But PrEP, if it is expected to reduce infections, needs to be prescribed for those most at risk. This is not as simple as it sounds, because HIV resources have so far been flung far and wide in Kenya, as if those who most need them will magically benefit.

The ruling assumption for high prevalence countries has been that 80-90% of all HIV transmission is a result of ‘unsafe’ sexual behavior. HIV prevalence is seen as a reliable indicator of ‘unsafe’ sexual behavior, and ‘unsafe’ sexual behavior, or perceived behavior, is seen as a reliable indicator of prevalence.

This is completely circular, of course. But if these prejudices are carried over from addressing the HIV positive population, and applied equally to the HIV negative population, the bulk of the drugs may as effectively be flushed down the toilet. The majority of Kenyans are, were, or will be sexually active. But the majority are not at risk of being infected with HIV.

Kenya’s HIV epidemic, in common with the epidemics in several other East African countries, is quite old. The virus has been circulating since the 50s and 60s, so the epidemic is about half a century old, give or take a few years. In other countries, such as the DRC, the virus has probably been around for about 100 years, although it must have affected only small numbers of people for many decades.

Don’t be fooled by figures suggesting that HIV has only been around since it was first recognized by doctors in the early 1980s (or just a little bit earlier), and later described by scientists. UNAIDS estimate that prevalence was already about 3% in Kenya by 1990, rising to over 10% later in the decade, to peak at almost 11%. From 2000, prevalence declined for a few years, rose again from 2005, then dropped to 6%.

This suggests that the rate of new infections (incidence) peaked and started to decline in the early to mid 90s, prevalence peaked and started to decline by the late 90s, and death rates would have peaked in the early 2000s. By 2007 prevalence was 8% and it is now 6%, so it has hovered between 6 and 8% for more than 10 years. Declines are slow, irrespective of major interventions.

Although the widespread use of ARVs, which began in the late 2000s, has contributed to a decline in new infections, prevalence and death rates, it is not possible to attribute these improvements to drugs alone. Making PrEP available to all those assumed to be ‘at risk’ of being infected, purely on the basis of the circular argument mentioned above means that this is going to be an expensive, but very ineffective intervention.

This sounds like bad news, but it doesn’t have to be seen that way. If the HIV risks people face could be identified, whether they are sexual or non-sexual, this will reduce the number of people who need PrEP. Most non-sexual risks, for example, exposure to blood and other bodily fluids through unsafe healthcare, cosmetic and traditional practices, are easily and cheaply avoided. No need to give PrEP to all the patients at a clinic when you could just clean up the clinic, right?

But also, things have changed, PrEP allows us to target those most at risk much more accurately than before. If people know they can protect themselves, they will. Clinics can now safely return to the practice of ‘contact tracing’, identifying how each person testing positive may have been infected, and then addressing that source of infection, whether it was a sexual partner, a clinic, a tattoo artist, or whatever.

The decision to discontinue tracing contacts, which was made in a very different context (a rich country, where the bulk of HIV transmissions were occurring among a relatively small population, and resulting from an easily identified set of behaviors) is inappropriate for a country with a massive HIV epidemic, where the risks have not been clearly demonstrated, and averted. In Kenya, for example, the majority of people who become infected with HIV do not face the high risks identified in rich countries, receptive anal sex and injecting drug use.

If identifying how people become infected can allow HIV negative people to avoid being infected, and allow HIV positive people to avoid infecting others, then contact tracing is vital in high prevalence countries. It is also vital if interventions such as PrEP are to be effective, or even affordable. Already, researchers have found that not being able to identify where the risks are coming from will significantly increase the quantity of drugs each person needs, in addition to vastly increasing the number of people deemed to be in need of PrEP.

Despite ample evidence that non-sexual risks are as important as sexual risks, evidence that has been available since the virus was first identified as causing Aids, most research concentrates on reporting sexual risk only, collecting data about sexual risks, recommending strategies to reduce sexual risks only, while ignoring, denying or failing to collect data on non sexual risks.

Mass ARV rollout complements pre-existing trends in HIV epidemics, though not as much as it could have, had the contribution of non-sexual transmission been acknowledged. However, PrEP will be a slow and inefficient solution unless targeted at those truly at risk, as opposed to the tens or hundreds of millions who are sexually active. People can only protect themselves if they know what the risks are, whether they do it by avoiding exposure, or by taking prophylactic drugs.

HIV in 'Africa':12 Steps to Unknowing Knowns

Sometimes it’s hard to believe that both sexual and non-sexual transmission routes for HIV were recognized in the early 1980s, even before the virus had been identified. Some of the earliest responses included recognizing lack of infection control in health facilities, and transmission rates are likely to have been cut substantially as a result of these responses alone.

The bulk of transmissions in rich countries, such as the US, are still accounted for by male to male sex, with a far smaller proportion being a result of injected drug use. But in poor countries, especially sub-Saharan African countries, where the majority of HIV transmissions occurred and continue to occur, most people infected are not men who have sex with men, nor injected drug users.

The ruling assumption behind HIV ‘strategies’ in high prevalence African countries became ‘promiscuity’. UNAIDS and the HIV industry grew up around claims that 80-90% of HIV transmission in African countries is a result of ‘unsafe’ heterosexual sex. Given the low probability of transmission during heterosexual sex, long-held notions about ‘African’ sexuality were dusted off, and spawned the behavior change industry.

Sex (among Africans, of course) came to be presented as an addiction, a pathological condition. Predictably, one of the most popular approaches to addiction, The Twelve Steps, was adapted for the behavior change sector. Billions of dollars were wasted on programs that were shaped by familiar assumptions about what ‘African’ men do to ‘African’ women, and how frequently.

It’s not clear how much George W Bush himself was involved in earlier versions of behavior change and abstinence only programs, claimed to reduce HIV transmission (and, eventually, eradicate it altogether). But he is likely to have been familiar with the Alcoholics Anonymous program, given his own experience with drink (and evangelical religion).

It would be tedious to go through every step individually, but it’s worth broadly comparing the 12 steps with received views about HIV in ‘Africa’. Aside from connections with a ‘higher power’, confessions, testimonials, evangelism and notions of ‘rescue’ or being ‘saved’, there’s also the oppressive emphasis on ‘abstinence only’ that has been the downfall of all 12 step programs, whatever they aimed to remedy.

It’s like the line in the movie ‘Burn Before Reading’: “Fuck you, Peck! You're a Mormon! Next to you, we all have a drinking problem!” All sex (in ‘Africa’) is ‘unsafe’ sex, all sex is wrong, all sexually active people are ‘promiscuous’, all HIV is either a result of ‘unsafe’ sex, or of contact with someone who engaged in ‘unsafe’ sex.

Why is the HIV industry so firmly wedded to abstinence only programs? They have failed for drink, drugs, sex, gambling, eating, smoking, etc; abstinence-only just doesn’t work. Since all the serious HIV epidemics in sub-Saharan African countries peaked and started to decline, mostly before these behavior change programs had been deified, many millions of people have been newly infected.

If sex were the only risk for HIV, almost everyone would be able to protect themselves, and most would do so. There would only be a minority for whom sex is an addiction, an occupational hazard or unavoidable risk that exposes them to HIV, STIs and other hazards. Most sexually active people are not ‘promiscuous’, and recognizing this is key to reducing HIV transmission in sub-Saharan Africa.

Choke on it: Peak Free Lunch at HIV Inc?

There have been several mentions recently of significant cuts in HIV funding, including PEPFAR and the Global Fund for Aids, TB and Malaria. It is said that funding could be cut by several billion dollars per annum, even as much as one third of all funding. Should we be worried?

According to UNAIDS, funding available for low and middle income countries has grown from $4.8 billion in 2000 to $19.5 billion in 2016. During that time, deaths from Aids have dropped from a peak of 1.9 million people in 2005 to 1 million in 2016.

The number of new infections has gone from about 4.7 million in 1995 to 1.8 million in 2016 and the number accessing treatment has gone from 685,000 people in 2000 to 19.5m people in 2016. The fear is that the number of deaths will cease to drop, or even increase, as the number of people on treatment flattens out or drops.

The gains over the last 15 years are certainly impressive, especially the increases in funding. But the correlation between increases in funding and improvements in HIV indicators is not so clear. Drops in rates of new infections had started many years before, and even death rates had peaked and started to decline before funds such as PEPFAR and GPATM would have had much impact.

In fact, figures for new transmissions in some high prevalence countries started to drop in the 80s (Uganda) and 90s (Kenya and Tanzania), long before big funding and large treatment programs were available. By the 2000s, several countries with serious epidemics were already seeing a substantial downward trend (Zimbabwe), with only an occasional upward blip, such as that experienced in Uganda.

Here are some ways that a lot more could be achieved with a lot less money:
  • Trace the possible source of every new infection; every new infection is potentially the source of more than one further infection, so failure to trace sources represents one of the biggest missed opportunities of the last 30 years of providing HIV services
  • Offer non-HIV healthcare services to those who test negative (as an incentive to testing), eg, free treatment for conditions other than HIV, including STIs
  • Re-examine the relative contributions of non-sexual and sexual infection routes for HIV, which must vary considerably from country to country, even within countries
  • Re-integrate HIV clinics and services into other health facilities, getting rid of expensive parallel HIV-specific structures
  • Distribute funding at a level closer to people on the ground, such as HIV positive people and those providing services
  • Re-direct some of the remaining funding to improving safety in certain service areas, eg, maternal health
  • ‘No blame’ investigations into serious outbreaks, especially among those whose risk should be low, eg, maternal health beneficiaries, virgins, infants, etc
  • Drop failing programs, such as abstinence-only and other behavioral programs that are aimed solely at sexual behavior
  • Listen to leaders who are calling for positive change, for things to be done differently, for a re-think of some of the strategies that have been failing for a long time
Big reductions in HIV funding could be used as an opportunity to make positive changes in the way the remaining funding is spent, and allow each dollar to go much further. Country leaders need to think differently, rather than chaining themselves to strategies that have been failing for years. Massive HIV NGOs and other institutions are too far removed from individual epidemics to be able to see differences between countries and within countries.

What we should worry about is stasis: static thinking in HIV institutions, static research focus in universities, static behavior in health facilities, static attitudes that have not moved on from the sensationalist finger-pointing of the 1980s. Static or falling funding is irrelevant so long as HIV spending remains independent of what’s happening on the ground. A radical drop in funding may bring about the very changes that have been wanting for decades.

Mandatory HIV Tests: Shouldn’t Zambians Decide?

The Lancet has an article by Andrew Green about the recent decision of the government of Zambia to introduce mandatory HIV testing in all government health facilities; if they visit a clinic, they must agree to be tested. Green urges against mandatory testing, using the often heard claim that people will be reluctant to go to health facilities if they think they will be compelled to take a HIV test.

It is argued that people could feel ‘stigmatized’ if they are found to be HIV positive, or perhaps even if they are just tested for it. Indeed, the orthodox view of HIV is that it is almost always sexually transmitted in African countries, and that there are excessively high levels of ‘promiscuity’ (in case you were wondering where the stigma comes from). Popular supporters of the orthodoxy, write: “Unprotected heterosexual sex drives the Zambian HIV epidemic, with 90% of new infections recorded as a result of not using a condom”.

Zambia ranks 7th in the world by HIV prevalence, around 13%, and 9th by number of people infected with the virus, about 1.2 million. The epidemic in Zambia probably started before the 80s because it had already reached 9% prevalence by 1990. Prevalence has stood at over 10% for about 25 years. It peaked in the mid 90s, so it has only dropped by a few percentage points in the past two decades. Population growth would suggest that new infection rates have not dropped at all.

Health Minister Chitalu Chilufya told Green “We can't continue doing things the same way and hope that things will get better”. Chilufya is a doctor, not just a politician, and it’s hard to disagree with his response. What has been done so far has failed. The epidemic has remained ahead of the HIV industry, with 60,000 new infections a year, far outnumbering the 20,000 deaths from AIDS. Maybe it’s time to do something different?

Green cites the World Health Organization as an authority for the view that testing should not be mandatory or coerced. But where does the view that people will stop going to health facilities come from? Is there any country that has made testing mandatory, and found that people stopped seeking healthcare of any kind? Perhaps people are more reluctant when it comes to HIV because they know that it is seen as an indication that they have been ‘promiscuous’. Might they be more willing to be tested if WHO drops their mantra about sexual transmission?

Cuba is an example of a country that has taken a very different path from almost every other country when it comes to HIV, and healthcare as a whole. Most countries are heavily influenced (dominated?) by the WHO, or by US funding and HIV ‘policy’. But things in Cuba couldn’t be more different from Zambia, and sub-Saharan Africa more broadly, with one of the best controlled HIV epidemics in the world.

The UNAIDS current ditty is ‘90-90-90’, at least 90% of HIV positive people tested, at least 90% of those found positive on medication and at least 90% with an undetectable viral load by the year 2020. So, what is their strategy to achieve this, aside from assuming that everyone should continue to copy all the failed strategies of the US, hoping that things will be different for them?

Targeting people thought to be at risk of HIV purely on the basis of their perceived levels of ‘promiscuity’ means those infected non-sexually, or at risk of being infected, will be missed. Unless they start to estimate non-sexual transmission sources, and start to reduce transmissions of this type, untold numbers of Zambians will be infected, and can go on to infect others, directly or indirectly.

If the orthodoxy are confident that 90% of HIV infections are sexually transmitted, they have nothing to lose by tracing people’s contacts, sexual and non-sexual. This doesn’t violate anything. HIV positive people have a right to know how they were infected and HIV negative people have a right to know how to protect themselves from risks. But if Zambia 'returns to the flock', and keeps all testing voluntary, what rights might this threaten?

If contacts are not traced, many people won’t know what the risks are, and therefore how to protect themselves. HIV positive people won’t know for sure how they were infected. According to the Lisbon Declaration on the Rights of the Patient, people are entitled to be informed of things like this by their health facilities, by healthcare personnel. People are also entitled to accurate health information and education. Where is this accurate information to come from if health facilities don’t collect it, or if it is never analyzed or followed up?

People have a right to know about hygiene, safety and infection control in health facilities, and similar information. It would be obtuse to argue for a right to health or healthcare, but against ensuring safe healthcare. In any population, including Zambia’s, there are unexplained transmissions. Examples include HIV positive virgins (who were not infected through mother to child transmission), HIV positive people who have never had sex with a HIV positive person, HIV positive people whose only sexual partner has tested HIV negative, HIV positive infants whose mother is negative, etc.

Green seems to be arguing on behalf of an orthodoxy that is afraid people will realize that there are non-sexual risks, as well as sexual, and that people have been systematically denied their right to this information. He seems to want to help cover up the fact that possible non-sexual infections that may point to unsafe healthcare, for example, have never been investigated in high HIV prevalence countries, or any countries whose HIV strategy is entirely dominated by the WHO, CDC, UNAIDS and the like.

Rather than challenging opposition to mandatory HIV testing, perhaps Zambia could investigate possible healthcare associated transmission of HIV. There is no violation involved if non-sexual contacts are traced, such as unsafe healthcare, traditional practices, or even cosmetic practices, such as tattooing. If Zambia doesn’t do something different, the epidemic could follow the Lindy Effect, lasting another 40 years. But the matter should be decided by Zambians, not by The Lancet.

America's Other Epidemic: HIV in Confederate States

Almost 70% of new HIV infections each year in the US are a result of male to male sex. The other 30% results from injecting drug use and non-male to male sex. But prevalence varies considerably from state to state. An estimated 45% of all HIV positive people live in the southern region of the US. Prevalence is also high in some northeastern states, especially in some cities.

The southern region consists of Alabama, Arkansas, Delaware, Dist. Columbia, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia and West Virginia. Prevalence is highest in the District of Columbia; at 3.61% that's higher than in 138 countries. Florida has the highest HIV positive African American population, 48,500 people, higher than in 109 countries.

In the southern states, an estimated 55% of the people living with HIV are African Americans. The figure for the Midwest is 47%, 42% for the Northeast and 18% for the West. Although African Americans only make up just over 13% of the population, almost half live in southern states, about 22 million people. And HIV prevalence among African Americans in southern states is 7 times higher than it is among white Americans.

Prevalence in every southern state is several times higher among African Americans than it is among white Americans; it’s 3 times higher in the District of Columbia and 9 times higher in Maryland. In 2014, almost half of all new HIV infections in the US were among African Americans and two thirds of people living with HIV in southern states are African Americans.

The contrast is also stark for heterosexual HIV: there were more than 4,600 female African Americans infected, compared to just over 1,100 female white Americans infected. Infections classified as ‘white heterosexual male’ are low in number, whereas an estimated 2,000 were classified as ‘black heterosexual male’.

Why would sexual behavior among African Americans, homosexual and heterosexual, be more risky than sexual behavior among white Americans? And why would sexual behavior be exceptionally risky in southern states? Or is there more to high HIV prevalence than levels of sexual behavior and types of sexual practice?

To put it another way, do African Americans tend to conform to the many stereotypes about them, such as levels of sexual behavior, types of sexual behavior, attitudes towards sex, etc? Or are there things about the environment, such as living conditions, economic and social conditions and conditions in healthcare facilities, for example, that increase the risk of infection that African Americans face?

It’s hard to know what conditions, exactly, could increase risk to such a degree, or even how. But there certainly are factors that are particularly acute in southern states. The bottom 11 states for life expectancy are in the southern region, as are most of the states with the highest incarceration rates. Almost all the poorest states are in the south. States with the lowest rankings for educational attainment, at all levels, are in the south. Rates of unemployment and homicide rates are high.

Of course, some of the southern states are among the richest by GDP, with the highest household income. But they also have the some of the highest levels of inequality, with several states ranking lowest for economic indicators and several ranking poorest in the US. As a result, most of the states with the lowest Human Development Index are in the southern region. Rates of religiosity are high.

Some sexual practices are low risk for HIV, some are high risk. But why do African Americans, gay and straight, face far higher risk of infection than white people? Prevalence in Somalia, Senegal, Niger, Sudan, Morocco, Tunisia and Egypt is lower than in the US (.6%). Prevalence in Burundi, DRC, Liberia, Burkina Faso, Eritrea and Mauritania is lower than in the US south (1.12%). HIV prevalence does not correlate well with sexual behavior data. So what other factors could be involved?

Is that Guardian Article Really Racist?

Accusations of racism against the two journalists (Samuel Okiror and Hannah Summers) who put their names to an article entitled “'Why are you having sex?': women bear brunt of Uganda's high HIV rate”, and even The Guardian itself, may sound unwarranted, insolent, even arrogant. Is The Guardian guilty of ‘deep racism in patologizing sex’?

No questions are raised about the long held assumption that HIV is ‘all about sex’. The authors seem to make the same assumption themselves. They don’t question people’s right to health information and to health education, which sex education is only a part of. These rights are very clearly stated in the World Medical Association’s Lisbon Declaration on the Rights of the Patient.

What about Uganda’s ban on sex education? The Guardian could have mentioned that, if they feel that this is so relevant to HIV. The tone and content of sex and sex education articles tend to be quite different when they are about sex in a UK or non-African context. Similarly with ‘Aids and HIV’. In the UK, people have a right to privacy, for example, but not in African countries, where a HIV positive diagnosis is assumed to indicate ‘unsafe’ sex, regardless of what the person may report.

The Guardian doesn’t wag its finger at adult men who have sex with adult men and tick them off about their ‘promiscuity’. But finger-wagging at adult men and women in high HIV prevalence countries in parts of Africa is routine, as if they are behaving like disobedient children. The Guardian doesn’t seem to notice these double standards.

The question ‘Why are you having sex? You should be married’? is said to be an instance of discrimination against young females who attempt 'to access HIV prevention services from the health sector'. But the Ugandan health sector is shaped and funded by an international community that insists that HIV is all about sex. The 'stigma' to which the article alludes comes from the HIV community, from the media, from governments and international communities.

Why more young girls than young boys: "Health experts have attributed the disparity to the fact men tend to have more sexual partners, so a man with HIV would spread the infection to more people". Aside from the logistics of that 'expert' opinion, it also seems to be based on the assumption that sex is usually instigated by men, with women usually being unwilling victims, that men are ‘more promiscuous’ than women, etc. Or perhaps those assumptions are totally absent?

While we are questioning differing prevalence rates by gender, what about some of the other figures gathered for Uganda and elsewhere (see Uganda Aids Indicator Survey, 2011 and others)? For example, why are there often large numbers of HIV positive virgins, who were not infected vertically? There have been cases of babies who seroconverted even though their mother were not infected. Some babies have infected their mothers, through breastfeeding. Many HIV positive women have one partner, who is seronegative.

There are so many discrepancies, aside from ones relating to sexual behavior, or appearing to. Why is high HIV prevalence clustered in just a few places in most countries (Kenya is a good example)? Why are rich people more likely than poor people to be infected? Why are employed people more likely to be infected than unemployed people? What difference does religious belief system make?

What is it about location, environment, economic circumstances, employment status and other factors that results in very high HIV prevalence in some countries, but not in others? The stock response from UNAIDS tends to be about differing ‘sexual mores’, differing sexual ‘mixing’ behavior in urban and rural areas, wealth inequalities (which result in more rich people paying for sex and more poor people engaging in paid sex, apparently), etc. It’s as if sexual behavior is the only determinant of HIV exposure and status, uniquely so among diseases, a complete epidemiological anomaly, and only in (some) African countries.

Instead of concentrating on sex alone, perhaps we could examine conditions in health facilities, and differing levels of access to health facilities, differing quality in health facilities, where only those with money, insurance, even transport and good infrastructure, can access? Some people are in a better position to protect themselves from non-sexual exposure to HIV, if only they also had access to accurate health information. Health funding, insurance and access will only improve health if it is high quality and safe healthcare.

The title and overall tone of the Guardian article concludes that 'it's all about sex', before anything else appears. No argument is given for their conclusion. Asia Russell of Health GAP is right to warn that the figures are for prevalence, an indication of how many people are infected with HIV in a population or group. This is not as useful a measure as incidence, which estimates how many people were newly infected with HIV, usually in a period of one year.

But neither prevalence nor incidence figures are relevant to the content of the article because the factoids are either based on opinion, or they are commonly held assumptions (some would say ‘prejudices’). These include assumptions about 'African' sexuality, attitudes towards women, underage sex, intergenerational sex, 'promiscuity', sexual practices, 'African' masculinity, the status of women, etc.

The article is about The Guardian's and its authors' prejudices, not about Uganda, HIV or 'Africans'. Presumably it contributes to, and also concurs with, the prejudices of Guardian readers, what they expect and perhaps enjoy reading about HIV, and sexual behavior in ‘Africa’.
The article does not draw attention to the fact that the health workers (ostensibly, those purveyors of (institutionalized) stigma and discrimination) make no mention of unsafe healthcare, 'informal' or unofficial healthcare, traditional healthcare and similar practices, cosmetic practices (such as tattooing) and others that could, however inadvertently, result in exposure to HIV contaminated blood.

At the end of the article we are told that the Ugandan health ministry has called for “concerted efforts from all stakeholders for scale-up of evidence-based interventions for sustainable HIV epidemic control”. But if those ‘evidence’ based interventions refer to the same prejudices and assumptions as the Guardian article, they will have no impact on transmission rates. What’s the point in scaling up interventions that have failed?

It’s the assumptions that are wrong, not the data. Prevalence rising or falling, incidence rising or falling, female rates higher or lower than male, none of these data can tell us how people are being infected with HIV. There is data suggesting that it’s not all about sex, but this is being ignored or reinterpreted.

The racism of The Guardian has disastrous consequences for people in high HIV prevalence countries. But the realization that HIV is not all about sex can only have positive consequences: people’s exposure can be reduced, perhaps totally eliminated. Accurate health information and health education, to which everyone has a right, can achieve this. Well informed, educated patients and healthcare practitioners can take action, raise awareness and change things for the better.

The Deep Racism of Pathologizing Sex

What are the assumptions behind an article entitled “'Why are you having sex?': women bear brunt of Uganda's high HIV rate”? Firstly, the bulk of HIV transmission is assumed to be a result of ‘unsafe’ heterosexual behavior. Secondly, the number of infected females outnumbers males by almost 2:1, but this is blamed on ‘male sexual behavior’ (white people protecting black women from black men, etc?). Thirdly, all 'Africans' engage in massive amounts of sex. Fourthly, ‘unsafe’ sex is the rule. Fifthly, they start young...the list goes on.

This claptrap is mixed in with pseudo-science: there is no evidence that a majority of HIV transmissions in African countries are a result of ‘unsafe’ heterosexual sex, only a lot of ‘expert’ opinion; indeed, the evidence shows that the majority of transmissions are very unlikely to be a result of ‘unsafe’ sex.

Figures cited for percentages infected, males and females infected, etc, are not incorrect, that’s not why I call them pseudo-science. The sleight of hand lies in the fact that they purport to bear some relation to the levels of sexual activity that would be required for Uganda’s epidemic to be overwhelmingly a result of heterosexual activity.

More than 80,000 Ugandans were said to have been newly infected in 2015. Given estimates that suggest the risk of transmission from a male to a female for penile-vaginal sex is 1/1,250 and the risk for a female to a male is 1/2,500, those 80,000 newly infected people could represent well over 100,000,000 sex acts.

The Guardian further claims that girls between 15 and 24 years old are infected at a rate of 570 per week, reflecting a further assumption, that sexual debut tends to be at an exceptionally young age in Uganda (not true, according to most research). Most young girls have not had hundreds of sexual experiences, even girls in their 20s. Some may have, but most have not.

Most people do not have hundreds of sexual experiences every year. That’s true in every country in the world, even in countries where The Guardian would have us believe they do, countries where HIV prevalence is high. A minority of people may have a lot of sexual experiences, a small minority, according to the copious quantities of data collected by some of the best funded HIV NGOs (hundreds of surveys here).

There are two blatant non sequiturs behind articles like this: one, sexual activity is an indication of HIV prevalence, and two, HIV prevalence is an indication of levels (and perhaps types) of sexual activity. Neither of these are supported by the evidence, only by the assumptions, the prejudices, the deeply held racism of the media and the international HIV industry.

One of the most egregious consequences of these racist views is that a lot of money and effort have been expended on useless ‘abstinence only until marriage’ programs (which could be better referred to as ‘abstinence only until death’). An update to an earlier meta-analysis of such programs concluded that:

“U.S. abstinence-only-until-marriage policies and programs are not effective, violate adolescent rights, stigmatize or exclude many youth, and reinforce harmful gender stereotypes. Adolescent sexual and reproductive health promotion should be based on scientific evidence and understanding, public health principles, and human rights.”

The Guardian article is pure speculation, with a handful of figures thrown in. There is the ever-present ‘expert’ opinion about why more women than men are infected, etc, but the only constant throughout the article is racism, about ‘Africans’, their implied sexual behavior, their attitudes towards women, especially young women...the rightness of the HIV industry and the wrongness of all 'African' people.

If this sort of article is to be believed, all sex is wrong in Africa, it's all 'unsafe', it should all stop. The men are cruel, the women are powerless victims and only non-Africans can diagnose what is going on there, phrenologize the population, profile the groups, strategize their rehabilitation and save them all from damnation ('Shut up and get back in your pigeon-hole, we were right all along!').

The assumption behind this Guardian article is that HIV is almost always heterosexually transmitted in African countries, and the only way this could be true is if ‘Africans’ really are as promiscuous, impervious to reason, cruel and thoughtless to those around them and, frankly, primitive and uncivilized, as the age-old prejudice says they are. As long as it’s about ‘Africans’, you can insinuate these things as often as you want in the mainstream media.

This kind of article can give the impression that apartheid never ended in South Africa. Instead, it spread all over the world, affecting people from African countries and people of African origin. Africans are still apart when it comes to HIV, infected in numbers that are orders of magnitude higher than among non-African people. 'Explanations' of high HIV prevalence tell us that 'Africans' really are different, that non-Africans don't behave the same way when it comes to sex, that there really is something 'other' about heterosexual sex among black people. Pure racism.

Voice of America: Masters of Clickbait

According to an article in Voice of America “Women and girls as young as 12 from Kenya's countryside are being forced into sex work to support families affected by prolonged drought.” The title of the article calls this ‘survival sex’, a popular media trope. The article goes on to claim that the area in question here, Turkana, “suffers from Kenya's second-highest HIV infection rate”, and attributes this to the IRC (International Rescue Committee).

This popular coupling of sex and HIV, spiced up with mentions of sex tourism, underage girls and the ‘survival’ element, is ubiquitous in the media. Even specialist publications about HIV seem obsessed with sexually transmitted HIV, to the exclusion of infections through unsafe healthcare, cosmetic care and traditional practices, which can all run the risk of coming into contact with blood. This can result in transmission of viruses such as HIV, hepatitis C and various others.

Two questions arise from this VOA article alone: first, what proportion of HIV is transmitted through sex, and what proportion is transmitted through other, non-sexual routes? And second, what is the relationship between food shortages and poverty in general on the one hand, and risky sexual behavior on the other?

In answer to the first question, VOA or the IRC, whoever came up with the figure, is wrong about Turkana having the second highest HIV prevalence in Kenya. The highest prevalence figures can be found around Lake Victoria, with Homa Bay having the highest, at 26%. National prevalence is said to be 5.9%. In comparison, prevalence in Turkana is 4%, and is claimed to have halved in the past few years.

Which leads to the answer to the second question: if poverty and food shortages have been increasing in Turkana for the last few years and HIV prevalence has been dropping, that may suggest that the correlation between the two is negative. Of course, what we really need to know is whether incidence, the percentage of new infections, is increasing or decreasing (along with an indication of how all these people are being infected, of course).

The VOA article goes on to mention sex tourism, ‘survival sex’, child sex, how little money those involved make, how they are exploited and often make no money at all. It’s extraordinary how data collectors can know so much, apparently, and yet still know next to nothing about how people are being infected. Immense amounts of data are regularly collected about sexual behavior in high HIV prevalence countries, always showing that the majority of people have sex, but also showing that only a minority have a lot of sex, a lot of partners, engage in practices considered risky, etc (you’ll find hundreds of reports on the DHS website).

The article mentions another dubious figure, this time from UNICEF: “In 2008, the United Nations Children's Fund estimated that 30 percent of girls in coastal Kenya were forced into prostitution.” This makes it sound like 30% of all girls in coastal areas are forced into prostitution; the claim is probably that 30% of people working in prostitution were forced. The second version is still highly questionable, though typical of UN offices, but the first version is simply not credible.

There is no intention to dispute claims that there are food shortages, poverty, prostitution, HIV and many other severe problems in Kenya and elsewhere. But the desperate attempt to connect HIV with sex, and adding in as many shocking practices as possible to help readers swallow the claim, distracts attention from how people are being infected; it distracts attention from unsafe and insanitary conditions in healthcare facilities (and, probably to a lesser extent, from dangerous cosmetic and traditional practices).

This VOA article is disingenuous in not checking its claims against readily available data. The IRC, like all international NGOs, is anxious to increase funding, and reducing HIV transmission, poverty and food insecurity are all laudable aims. But the sloppy sensationalism in the article also leaves the impression that the claimed concerns about the dangers of ‘survival sex’, child sex tourism and child prostitution are being inflated for fundraising purposes. It also raises important doubts about what proportion of HIV is sexually transmitted.

Missing the Point: Bloodborne HIV in Malawian Prisons

Journalists can never resist anything they interpret as being 'evidence' of sexual practices in prisons. For example, an article about HIV prevalence in a prison in Malawi concludes that it must all have been transmitted sexually, and rants on about homosexuality, with prurient rubbish about whether the distribution of condoms does or does not 'promote' homosexuality.

This article cites an odd finding: "A recent screening exercise conducted by the Malawi Prison Services at Chichiri Prison in the commercial city of Blantyre revealed that out of 1880 inmates tested for syphilis, 46 were diagnosed positive. The exercise also revealed that out of the 1,344 inmates screened for HIV, about 100 were diagnosed positive and 62 of them were newly infected."

That means syphilis prevalence stands at 2.5%, yet HIV prevalence stands at 7.4%. As syphilis is generally easier to transmit sexually than HIV, the fact that HIV prevalence is three times higher may suggest that much of it is not sexually transmitted.

For example, there could be some questionable practices in the prison healthcare facility, including unsafe practices among those administering first aid. There could also be traditional or prison related practices that risk bloodborne transmission of HIV, hepatitis and other conditions, such as tattoos, blood oaths, traditional medicine, etc.

There may even be illicit drugs administered in a way that risks bloodborne transmission of viruses and infections. Indeed some could argue that, since HIV prevalence in this prison is lower than prevalence nationally, which stands at 9%, perhaps there are a lot fewer risks in prisons than in the general population, sexual and non-sexual risks?

Constantly associating HIV with sexual and homosexual practices reinforces the view that HIV is always transmitted through sexual contact of some kind. As a result, people fail to take precautions against non-sexual transmission risks, of which there are many.

The article goes on to bemoan colonial-era laws prohibiting homosexuality, the evident influence of some evangelical churches, social 'conservatives' and other misanthropes. But this misses the point that it is the entire HIV industry that goes to great lengths to distract attention from non-sexually transmitted HIV, through unsafe healthcare, cosmetic and traditional practices.
