The HIV denial movement has for the most part been a silly sideshow, an irritating distraction, to the massive international research effort into preventing AIDS. That’s in the West, though, where public health officials tend to be appointed on their merits. In Africa, the HIV denial movement is not limited to a handful of shonky scientists, but includes the President and the health minister of South Africa. The South African government just announced a major change of heart: it will now be looking at scientific approaches to the prevention of AIDS, including anti-retroviral drugs for the poor and credible sex education. Of particular note is that this announcement has come from the deputy president, not the President himself or the health minister, so it is hard to gauge how seriously to take it. But even if it is genuine, it is far too late for millions of Africans. Depending on the study, the prevalence of HIV in South Africa ranges from 11% to 25% of adults. And by denying the scientific basis of AIDS, the South African government has given credibility to folk medicine, which includes the contemptible belief that having sex with a virgin will cure men of HIV — the result being a surge in child rape cases by HIV-positive men.
Well, you might say, that’s Africa. It couldn’t happen here…
But it could. In fact, it’s happening right now, albeit on a much, much smaller scale. A West Australian man convicted of risking women’s lives through sexual contact will base his appeal on HIV denial. According to ABC Online:
Andre Chad Parenzee is awaiting sentence for having unprotected sex with three women who were unaware he was carrying the HIV virus.
But his lawyer, Kevin Borick, today argued that Parenzee’s conviction should be quashed because there is no scientific proof that HIV actually exists.
Mr Borick will call evidence from two Western Australian based scientists, who will argue that the virus has never been isolated, current testing regimes are inconclusive and that there is no proof HIV is transmitted sexually.
Australia is never going to face the disaster that is facing South Africa. When I say this is on a smaller scale, it’s like a teaspoon to South Afrrica’s ocean. We have a public health system that, whatever its flaws, strives to implement the best available scientific evidence, without political or financial corruption, and the Australian population is reasonably knowledgeable about HIV so rogue opinions are unlikely to gain a beachhead. But even if HIV denial never takes hold in the wider community, as long as there are damn fool scientists prepared to dress up their unfounded opinions as courageous skepticism, there will be a small number of individuals who will seize on those opinions and act as if they were true because they want them to be true.
It is, I hope, unlikely that Mr Parenzee’s appeal will succeed. But even if it fails, it appears that at least one lawyer is prepared to make the case and at least two scientists are prepared to testify in support, and this is all it takes to create a seed of doubt. The MMR-autism crisis in the UK was sparked by a single scientist despite the rapid and forceful debunking by every medical expert and public health body in England.
Next time you think HIV denial is a big problem for Africa but a mere lunatic fringe in Australia, you may be interested to know that even into the 1920s it was a common belief among British and European men that having sex with a virgin would cure sexual infections. As the saying goes, old fallacies never die. They just change their spots. Ask yourself how you would feel about HIV denial if you or your daughter were in the same position as the three women of Mr Parenzee’s acquaintance.

Imagine that a multi-million dollar drug company secured a deal with a local council to trial a product on schoolchildren. Imagine that the drug is marketed as improving children’s concentration and learning, but has no reliable evidence behind it. Imagine that the “trial” turns not to have a control arm, which means the study can’t actually measure the effect of the drug. Imagine, further, that the company arranged the trial as part of a major marketing drive aimed at parents keen to improve their children’s school grades.
In 1999 Canadian author Peter Watts made a big splash with Starfish, his ‘New York Times Notable Book of the Year-listed’ debut thriller about a group of misfit bio-engineered humans sent deep underwater by a multinational corporation to harness the geothermal energy of Channer vent on the Juan de Fuca Ridge. This time Watts turns his attention upwards, tackling the starscapes of outer space rather than undersea, bringing with him the biologist’s eye view that made the Starfish trilogy so compelling, disturbing and utterly fascinating.
