UNAIDS: Mythmakers or Liars?

We have spent the last few days in Bukoba, talking to people about their memories and perceptions of HIV. Unfortunately, after decades of being told that HIV is primarily spread sexually, most people firmly believe that this is the case. They believe that HIV came from ‘somewhere else’ (Uganda, America, Europe, truck drivers, sex workers, men who have sex with men, etc), a widespread belief. In Bukoba, they believe (mostly) that it came from Uganda and this may be true. Alternatively, HIV may have spread from Tanzania to Uganda at the same time as it was spreading from Uganda to Tanzania. It seems likely that HIV spread in waves at various different times and its impact in a particular place depended on many of the conditions extant in that place at the time.

The problem with ignoring non-sexual transmission of HIV, through unsafe medical practices or through cosmetic or other practices where blood or bodily fluids may be involved, is that people end up not looking out for such risks. Even where they recognise their existence, they don't know how to protect themselves. For instance, people know that hairdressers should sterilize their equipment between clients but their neither the hairdressers nor the clients know what is required for equipment to be properly sterilized.

Contrary to widespread belief, HIV does not die after seconds or minutes of being separated from the host. It can live for hours or even days on instruments that dry out. And it can live for weeks if it remains wet. If a hair trimmer is used on a person with a disease that is transmissible through blood contact, it needs to be boiled. Just cleaning it in water is not enough, nor is wiping it with methylated spirits or bleach. Yet, people are convinced that this is enough. They even admit that they don't know one way or another what is done with the instruments. Manicurists just turn up with a bucket of instruments and do their work before going on to another client. They don't have the equipment necessary to sterilize their tools, nor do their clients seem to be aware that this is very dangerous.

One person we talked to said that she uses a hair relaxant that burns the skin and makes it liable to break. Hair relaxants are popular here, to produce straight hair. So combs and anything else used would need to be carefully sterilized, but the facilities for doing this are often not available. As a hairdresser, she was unaware that it is not just blood that can transmit infection. Pus is even more dangerous. She was under the impression that if people had sores on their head, this was not risky unless there was also blood. Decades of warnings about the risk of HIV infection have concentrated almost exclusively on sexual behaviour and sexual risk. So people are not adequately prepared for non-sexual risks.

Similarly, risks from unsafe medical procedures could be much more of a threat than sexual risks. People's perception of medical risks is that they will be taken care of by health professionals. This may be true in some cases, but not all medical procedures are carried out by health professionals or in ideal conditions. You can get injections, and possibly other services, from people who run 'pharmacies', often just stalls that have a few medicines. Needles may well be changed between patients. One certainly hopes so. But are syringes always changed? Many people say they don't know and they don't feel they are in a position to question doctors and other health professionals. And many injectible products are sold in multi-dose vials. But it has long been known that vials can become contaminated. This can easily lead to HIV and other diseases being transmitted to many people.

People may face threats that they don't even realise are there. And they may face threats that they have never been told how to deal with. There are ways to take precautions against non-sexual transmission of HIV (and other blood borne diseases) but HIV education campaigns concentrate almost exclusively on sexual risk. Although some people can trot out a list of other HIV threats, including shared razors, toothbrushes, cosmetic equipment and medical equipment, these are considered to be relatively unimportant compared to the risk of sexually transmitted HIV.

UNAIDS publishes a list of recent HIV related publications, along with the abstracts and some editorial comments. This list very rarely includes papers that discuss non-sexual HIV transmission, concentrating instead on the many articles that look at sexual risk or what is perceived as sexual risk. So, for example, there's an article about sex work and the 2010 World Cup in South Africa. There are warnings about the risk of becoming infected with HIV and other sexually transmitted infections, but none about the risk people may face if they have to go to a medical facility for treatment or if they visit a tattoo parlour or if they get their hair cut. And South Africa is a country with very high HIV prevalence.

Another article that UNAIDS highlights is about sexual behaviour trends in France from 1970 to 2006. Sexual behaviour became more 'risky', especially for women, during the period. The same trends in a high HIV prevalence country would have been blamed for high levels of HIV transmission. But because this is a low HIV prevalence country and European, no such pronouncements are made. Non-penetrative sex also appeared to become more often practiced, which, of course, is less of a risk when it comes to HIV or sexually transmitted infection risk. But in some African countries, sexual risk behaviours are low but HIV prevalence is high.

When the survey takes place in a country like France, people's responses tend to be believed. Similar surveys in African countries can elicit similar results, but the responses tend not to be believed if they don't correspond with the data collected on HIV. When, as is often the case, people in African countries say they have not had sex, they have not had risky sex or that they took precautions against risk, and they turn out to be HIV positive, it is assumed that they are lying, mistaken or forgetful. Yet, many of them are likely to be telling the truth but they were infected by some non-sexual route, medical, cosmetic or the like.

Similarly, women have often been infected with HIV while they are pregnant. They are tested early on in their pregnancy and initially found to be negative. But they are subsequently found to be positive when they are retested later. The earliest period of HIV infection is the most virulent. If a woman becomes infected while she is pregnant, the chances of HIV being transmitted to the infant is far higher than if she seroconverted some time before becoming pregnant. The conclusion of this paper is that couple counselling may reduce unprotected sex during pregnancy. But have the authors considered the possibility that some of the women were infected non-sexually? Did they even test the husbands to see if they were also HIV positive? Of course, if the husbands were HIV negative, the belief that HIV is usually transmitted sexually leads to the conclusion that the woman must have had sex with someone other than her husband. This is one of the reasons HIV has become so stigmatized. Husbands often accept the received view about HIV being mainly sexually transmitted. They believe the ‘experts’, not their wives.

There are many hints that a good deal of HIV is not sexually transmitted in African countries. So it's surprising that UNAIDS, WHO and others still hold on to the view that non-sexual transmission accounts for a very small proportion of all incidence. In most African countries, various prevention programmes have been run, some for many years. But these programmes are almost all aimed at influencing sexual behaviour. Very few are aimed at medical transmission and even fewer at cosmetic transmission. And these programmes have been quite unsuccessful. A number of papers have asked questions about which prevention interventions work and, on finding that none of them make much difference to HIV transmission, they keep looking for new ways of preventing sexual transmission. They don't seem to consider the possibility that at least some transmission is not sexual, though they admit that conditions in medical facilities are too dangerous to allow UN employees to risk using them! These papers are right to conclude that gender, poverty and alcohol consumption are important when it comes to sexual transmission of HIV but they are probably not so relevant when it comes to non-sexual transmission. Or, at least, they would be relevant for quite different reasons.

Similarly, a lot of research has shown that behavioural differences don't explain variations in HIV prevalence among young people in African countries. High levels of sexual risk behaviour can be found in places with low HIV prevalence and low levels of sexual risk behaviour can be found in places with high HIV prevalence.

How much evidence does it take for the 'experts' at UNAIDS to conclude that their long held view is wrong, that most HIV is not transmitted by heterosexual sex? How much evidence do they need to find it worth their effort to investigate places where many young children are found to be HIV positive when their mothers are not? If UNAIDS recognises the dangers of allowing its own employees to use medical facilities in African countries, when will they admit that Africans living in those countries also face risks?


It’s very disturbing to hear people saying that they think HIV was created in a laboratory in America and spread deliberately, for whatever reason this might have been done. But it’s hard to shake people’s beliefs in conspiracies when they are constantly being told things that don’t make sense. Many people here know that Africans are not so different from people in other countries that their sexual habits could be almost wholly responsible for the very high rates of HIV transmission you see in some countries. But those who feel they know most about the disease assure them that this is, indeed, the case.

Those who feel they are HIV experts continue to assert the racist view that some Africans have so much more risky sex than people in other countries, it’s no wonder that HIV prevalence is very high in some places. Africans are being lied to, just not in the ways they think. The people who are tasked with eradicating HIV know that the risk of non-sexual transmission of HIV is so high that they need to protect their own employees. They just don’t tell Africans that. As a result, Africans continue to take risks that they could and should avoid. When people know about the risks they face and they know how to take steps to avoid them, HIV transmission rates will go down. But as long as the sexual behaviour paradigm clouds all HIV prevention activities, several more people will be infected with HIV for every one who receives treatment.
