As I write this, in the late winter of 2006, we are more than twenty years into the AIDS era. Like many, a large part of my life has been irreversibly affected by AIDS. My entire adolescence and adult life – as well as the lives of many of my peers – has been overshadowed by the belief in a deadly, sexually transmittable pathogen and the attendant fear of intimacy and lack of trust that belief engenders.

To add to this impact, my chosen career has developed around the HIV model of AIDS. I received my Ph.D. in 2002 for my work constructing mathematical models of HIV infection, a field of study I entered in 1996. Just ten years later, it might seem early for me to be looking back on and seriously reconsidering my chosen field, yet here I am.

My work as a mathematical biologist has been built in large part on the paradigm that HIV causes AIDS, and I have since come to realize that there is good evidence that the entire basis for this theory is wrong. AIDS, it seems, is not a disease so much as a sociopolitical construct that few people understand and even fewer question. The issue of causation, in particular, has become beyond question – even to bring it up is deemed irresponsible.

Why have we as a society been so quick to accept a theory for which so little solid evidence exists? Why do we take proclamations by government institutions like the NIH and the CDC, via newscasters and talk show hosts, entirely on faith? The average citizen has no idea how weak the connection really is between HIV and AIDS, and this is the manner in which scientifically insupportable phrases like “the AIDS virus” or “an AIDS test” have become part of the common vernacular despite no evidence for their accuracy.

When it was announced in 1984 that the cause of AIDS had been found in a retrovirus that came to be known as HIV, there was a palpable panic. My own family was immediately affected by this panic, since my mother had had several blood transfusions in the early 1980s as a result of three late miscarriages she had experienced. In the early days, we feared mosquito bites, kissing, and public toilet seats. I can still recall the panic I felt after looking up in a public restroom and seeing some graffiti that read “Do you have AIDS yet? If not, sit on this toilet seat.”

But I was only ten years old then, and over time the panic subsided to more of a dull roar as it became clear that AIDS was not as easy to “catch” as we had initially believed. Fear of going to the bathroom or the dentist was replaced with a more realistic wariness of having sex with anyone we didn’t know really, really well. As a teenager who was in no way promiscuous, I didn’t have much to worry about.

That all changed – or so I thought – when I was twenty-one. …….

The rest is here.
