Why Contact Tracing is Vital in High HIV Prevalence African Countries


A recent blog post I wrote received some comments from ‘Brad’, at The Mosaic Initiative, a grassroots organization based in the US. Although Brad seems to think that what I wrote accords in some way with what he believes, it is quite clear to me that we both think very different things about HIV.

For a start, I believe that HIV epidemics in African countries are NOT like HIV epidemics in the US and other Western countries. The bulk of HIV transmission in Western countries is a result of either male to male sex or injected drug use. The bulk of HIV transmission in African countries is not a result of either of these, in any country.

The very point of the Don’t Get Stuck With HIV website and blog is that no African country has made a convincing estimate of the proportion of HIV transmission that is a result of sexual, as opposed to non-sexual transmission. It is just assumed that about 80% is a result of heterosexual sex and most of the remaining 20% is accounted for by mother to child transmission; these assumptions have been held for more than 20 years and emanate from WHO, the World Bank, UNAIDS and other institutions that control HIV funding, globally and in African countries.

I also disagree with Brad that it is merely “important to know how HIV is spreading”; it is vital to know whether someone was infected through sex, through unsafe healthcare, through some traditional practice or in a tattoo studio. There is no “generalized pandemic” that Brad speaks of. In Western countries, the vast majority of people are not at risk of being infected with HIV. Even in African countries some people are more likely to be infected than others; in Burundi HIV prevalence is low, but in Botswana it is high. In cities, even Bujumbura, prevalence tends to be high.

Prevalence is almost always higher among women than men in high prevalence African countries, higher among employed people than unemployed people, higher among wealthier people than poor people, etc. There is a huge level of heterogeneity, between and within countries. This heterogeneity does not seem to correlate very much with sexual behavior, though you may believe otherwise if you have immersed yourself in HIV industry literature.

For example, birth rates are high in Kenya’s Northeastern Province, condom use is low, education is low, poverty is high, intergenerational marriage and sex rates are high, all things thought to relate to high HIV transmission; but HIV prevalence is the lowest in the country, lower than in some US cities.

The problem with the approach of UNAIDS and others is not that they employ ‘targeting’, as Brad suggests, but that their assumption implies that all sexually active people who engage in heterosexual sex are equally at risk in African countries. You can’t ‘target’ everyone in a population, or even half or a quarter of hundreds of millions of people.

Although UNAIDS and others claim that the bulk of HIV transmission is a result of heterosexual sex between people in long term monogamous relationships, with the implication that one or both partners must have had ‘unsafe’ sex outside of their relationships, they do not carry out contact tracing, that is, investigating ALL the possibilities for how each person was infected.

Most of the emphasis is on sexual transmission, and even then, sexual partners are usually not tested; when they are tested the HIV types are usually not matched. Therefore, it is almost always unknown how each person was infected, even though it is almost always assumed, in the absence of data to prove it, that each infection was a result of ‘unsafe’ heterosexual sex.

Effectively, UNAIDS and others in the HIV industry are not targeting any group because they don’t have a clue where to look. They assume that almost everyone who is HIV positive engages in ‘unsafe’ sex; they also assume that anyone who engages in any kind of sexual activity they consider to be ‘unsafe’ is a ‘risk group’, and that IS every sexually active heterosexual (or heterosexual who has sex with heterosexuals, or whatever nomenclature you care to adopt).

HIV status is not an indication of sexual activity, ‘safe’ or ‘unsafe’; and sexual activity is not an indication of HIV status or HIV ‘risk’. People in the US and other Western countries may object to contact tracing but in African countries it is vital. It has been avoided in African countries precisely because some have decided that it is a ‘bad thing’, that it ‘stigmatizes’ people, but as a result ALL African people in high prevalence countries have been stigmatized. The situation in Africa is not like the situation in Western countries and the sooner the HIV industry realizes that, the better.

Tanzania: HIV Industry Still Failing to Collect Data on Non-Sexual Transmission


One of the many damaging consequences of assuming that HIV is almost always transmitted through usafe sex is that those working with HIV tend not to notice non-sexual transmission, such as through unsafe healthcare, traditional and cosmetic practices. This blog and site is littered with examples of these modes of transmission, and of the HIV industry studiously ignoring every instance of transmission that they can’t explain away as being somehow related to sexual transmission.

High rates of transmission among ‘older’ people, which refers to people who are more than 49 years old (my current age), always comes as a surprise to those working for the industry. The Victorian prudishness that seems to affect people working with HIV means that they believe everyone gives up sex at some arbitrary time in their lives. Bizarre!

But older people, and that means people over 50 in developing countries, where life expectancy is much lower than in Western countries, don’t only continue having sex. They may also require health services more frequently than younger people. While that may not surprise those in the HIV industry, they have had a lot of trouble with the notion that understaffed, underfunded, underequipped health facilities may not be able to provide the safest health services in the world.

Research carried out in Tanzania finds that HIV prevalence among people from 50-98 years was 7.8%, compared to the national figure of 5.1% for people aged 15-49 years. HIV prevalence was higher in urban than rural areas, in common with figures for Tanzania as a whole [note that this is the opposite to what is stated in the abstract but I’m assuming the following text and data are correct]. While prevalence was a very high 12.9% among people 50-59 years old, it dropped to 5.7% among the 60-69 years age group and 3.7% among the 70+ age group.

The two areas for which data was collected, Mufindi and Babati, are in one of the highest (Iringa) and one of the lowest prevalence regions (Manyara), respectively, in mainland Tanzania. Prevalence among 50-98 year olds was 3.7% in Babati and 11.3% in Mufindi. The figure for Mufindi is not so shocking compared to Iringa’s 9.1% prevalence; in contrast, the figure for Babati is more than double the figure for Manyara region, which stands at 1.5%.

But it’s a pity the breakdown for male and female figures for each area is not available. The ratio of female to male prevalence in Iringa is 63%, similar to the national figure of 61%. But the same ratio in Manyara is 11%; there are about 9 HIV positive women for every HIV positive man. Is this shocking ratio maintained among people between 50 and 98 years old?

As is usual with these studies, no data was collected about non-sexual transmission, whether through unsafe healthcare, traditional or cosmetic practices. While the authors conclude that interventions should now target ‘older’ people, they fail to consider non-sexual HIV transmission, which means that some of the most important risk factors will continue to be ignored, and HIV will continue to be transmitted, independent of anything the HIV industry spends its millions on.

Borborygmus: Recent Contributions to HIV Epidemiology


David Gisselquist has already written a critical reaction to Jacques Pepin’s latest attempt to rewrite the history of HIV and unsafe injections. But AidsMap has gone in the opposite direction, by writing a completely uncritical, triumphalist regurgitation of Pepin’s paper, without finding anything strange about this ‘study’.

It’s odd enough that Pepin’s findings happen to match earlier claims from him and others, some made quite a number of years ago, as if simply wishing away HIV transmission through syringe and needle reuse were enough to almost eradicate it completely.

But in the ten year period Pepin is dealing with, sexual transmission has received almost all the attention and funding; yet the contribution of sexual transmission must have increased if Pepin is correct. At the same time, non-sexual transmission, which has yet to be addressed, even acknowledged by the HIV hierarchy, has dropped by almost 90%, a truly etymological decimation.

Pepin’s estimations, the provenance of which are very unclear, fly in the face of data collected by the Kenya Aids Indicator Survey. A paper using data from this survey finds that men who have had one or more injection in the previous 12 months were three times more likely to be HIV positive and women were two and a half times more likely.

The minute number of HIV transmissions that Pepin estimates were a result of unsafe medical injections in a year globally, 17,000-34,000, could be closer to the number of HIV transmissions in Kenya alone that were transmitted through various non-sexual routes.

Vague proportions of HIV transmission through sexual and non-sexual modes are estimated using the thoroughly flawed Modes of Transmission Model, which is well criticized on this site. So it remains a mystery what Pepin is talking about. Kenya is unlikely to be the only country where unsafe healthcare contributes a substantial proportion of HIV transmissions; but it is one of the few countries in Africa that has carried out any research into this phenomenon.

UNAIDS’ Garbage In Garbage Out Strategy Found Fit For Purpose


Although a Journal of the International AIDS Society (JIAS) paper, which ostensibly analyses Modes of Transmission (MoT) data and reports, has been through some kind of peer review process, the term ‘systematic’ in the title is misleading. In fact the review is highly selective. The phenomena of HIV infection through unsafe healthcare, traditional and cosmetic practices have been left out completely. This is despite the ready availability of relevant and up to date papers about these phenomena.

The Don’t Get Stuck With HIV website is a repository for many relevant materials. David Gisselquist also made a paper available last year that they have completely ignored, entitled ‘UNAIDS’ Modes of Transmission Model Misinforms HIV Prevention Efforts in Africa’s Generalized Epidemics‘. The bibliography therein should be very useful for anyone who wishes to carry out a systematic review in the future.

The JIAS study mentions recommendations from a 2012 set of guidelines produced by an MoT ‘study group’ and one of them recommends to “Adopt a bottom-up approach, that is, an approach that ensures that sufficient data is available to parameterize the model before making changes to tailor the MOT to more finely represent the local setting”.

The fact that no data has ever been collected by MoT studies for non-sexual HIV transmission may explain why such modes of transmission are ignored by the JIAS study. But it doesn’t explain why non-sexual transmission receives so little attention in the HIV literature as a whole, aside from peremptory denial of its existence.

Gisselquist recently pointed out some of the most glaring flaws in the MoT methodology in a brief blog post. But even the JIAS paper itself unearths some remaining flaws that make one wonder why such a weak and fragile tool should still be used after about a decade of demonstrations of its uselessness.

Ironically, MoT tools were supposed to contribute to UNAIDS’ ‘Know Your Epidemic, Know Your Response’ strategy. This strategy, like all UNAIDS strategies, is based on the assumption that almost all HIV transmission in African countries is a result of heterosexual transmission. That means that the majority of people in high prevalence countries are said to be ‘at risk’, either of becoming infected or of infecting others. So every African HIV epidemic looks pretty much the same to UNAIDS because of the built in assumptions of their various ‘tools’.

Therefore, a strategy for ‘targeting’ those most at risk ends up not targeting anyone; HIV interventions must aim to cover entire populations. Aside from being a waste of money and time, as well as stigmatizing the most affected populations, UNAIDS have failed to account for the bulk of transmissions in high prevalence countries. The two decade old, phenomenally expensive institution throws up its hands and says that the majority of people at risk of being infected are people who fall into ‘low risk’ categories.

Despite scratching the surface of the Modes of Transmission Model and finding that that’s all there is to it, the JIAS paper concludes that some aspects of it need to be ‘revised’. Which is even more misleading than calling the paper a ‘systematic’ review. But if UNAIDS have achieved anything in the last two decades it is in showing that a garbage in garbage out strategy really does work, and may continue to attract funding for another 20 years, at least. I wonder how many of the authors of the paper will end up working for UNAIDS, if they haven’t already done so.

HIV Transmission Via Unsafe Medical Injections in Kenya – Significant Risk


Congratulations to Kenya on being one of the first African countries with a serious HIV epidemic to investigate the role of unsafe healthcare and reuse of injecting equipment in transmitting HIV. The study finds that “Men who had received ≥1 injection in the past 12 months (adjusted odds ratio, 3.2; 95% CI: 1.2 to 8.9) and women who had received an injection in the past 12 months, not for family planning purposes (adjusted odds ratio, 2.6; 95% CI: 1.2 to 5.5), were significantly more likely to be HIV infected compared with those who had not received medical injection in the past 12 months.

But these findings make the conclusion of the article all the more striking: “Injection preference [my emphasis] may contribute to high rates of injections in Kenya.” If someone is infected with HIV as a result of receiving an injection, then it is the behavior of the health care practitioner that is at fault, not the ‘preference’ of the patient. Health facilities make more money from procedures such as injections than they do from just giving advice or handing out prescriptions, so there may be good reasons why patients ‘prefer’ injections; they may have been led to believe that injections are ‘better’. I’d also be surprised if mere patient preference made much difference to the kind of treatment a patient received in Kenya or elsewhere in East Africa.

Those providing health services need to take responsibility for healthcare associated HIV transmission, and that includes Ministries of Health, professional bodies, and also the WHO, UNAIDS, CDC and other parties who have dominated health and HIV policy in high HIV prevalence countries for decades. Reuse of syringes, needles and other skin piercing equipment carries a very high risk of transmission of HIV, hepatitis and other pathogens. It is not enough to blame patients for their ‘preferences’. Practitioners can decide what treatment a patient needs and what is the best means of administering it, if that means is available to them.

The paper recommends that “community- and facility-based injection safety strategies be integrated in disease prevention programs”. If this is UN-speak for the need to accept that HIV is frequently transmitted through unsafe healthcare and these practices need to stop, then I wholeheartedly agree. This is more than thirty years too late, but it’s good to hear the very mention of non-sexually transmitted HIV in the form of unsafe healthcare being taken seriously in a peer-reviewed journal. I look forward to hearing of other high HIV prevalence countries making the same ‘discovery’ and publicizing it, and also taking steps to reducing such transmission risks.
