When Will UNAIDS Be Abolished?

When people find used hypodermic needles in areas where children play in Western countries, they are upset. Quite rightly so. They don't like the thought that their children are being exposed to injury and diseases, possibly even serious or deadly diseases.

But even many Westerners seem to believe that HIV 'dies' within seconds, minutes or some fairly short period, outside of the body. This is not what the US Center for Disease Control (CDC) says on the subject, although it may have said that at one time. Their current answer to the question 'How well does HIV survive outside the body?' is difficult to interpret.

But no matter how you interpret the risk, no one wants a possibly contaminated needle piercing their skin or that of their children. As well as the physical injury, there is also a risk that the needle is contaminated with hepatitis and it is almost certainly contaminated with bacteria.

So the CDC's comment about 'incorrect interpretations' of risk causing 'unnecessary alarm' seems injudicious. I know the question is about HIV but the answer really needs to address risk as a whole. Potentially, HIV can survive for days and even weeks, under the right conditions. Contact with contaminated needles and other instruments should be avoided and where this is not possible, medical advice is required.

However, the idea that the HIV does not live outside the body is widely held, by professionals and lay people. And in countries like Kenya, Tanzania and Uganda, it is far more dangerous to be unaware of the risks. The chances of medical or cosmetic equipment being contaminated in countries with high prevalence of HIV, hepatitis and other diseases can be very high.

You might think that there would be a lot of awareness of these risks and how to avoid them but I have rarely spoken to anyone who has considered the risks they face from contaminated instruments in health or cosmetic facilities.

UNAIDS dismisses the importance of any form of non-sexual HIV transmission, let alone transmission in health facilities. They grudgingly accept that a few percentage points of HIV transmission in East African countries may come from such routes. But they hardly mention cosmetic instruments, razors, tattooing equipment and the like, at all.

As a result, such transmission may be occurring at high rates and people are doing nothing about it. When they take their child to the hairdresser, or go themselves, they could be picking up scabies, hepatitis, HIV or some kind of bacterial infection. To help people avoid these risks, the best thing to do would be to inform them.

Risks in health facilities are more difficult to handle. Doctors, nurses and other health personnel can be pressed for time and it is not easy for patients, or those accompanying patients, to intervene. At best, personnel will be annoyed, at worst, they will refuse to treat the patient, give them poorer quality treatment or make them wait a long time.

The WHO has published data showing that as much as 14% of injections in developing countries are contaminated with HIV and they have unpublished data showing that this figure can be a lot higher. A large proportion of hepatitis B and C is transmitted through contaminted needles. And an estimated 70% of all injections are not even necessary.

When there is even the hint that someone in a Western country may have come into contact with contaminated equipment, there is an investigation to establish how procedures could have resulted in such a risk. And anyone who may have been affected, even going back years, and through thousands of records, is contacted and screened.

Not only does this sort of investigation and screening of possible use of contaminated equipment not take place in developing countries but UNAIDS and others seem keen to deny that such things, which happen in the best resourced health systems in the world, could possibly happen in the worst resourced health systems in the world.
