Okay, back to this. Duesburg is a crank. Do you what the defining attribute of a crank is in my eyes? A “scientist” (as more often than not these people are not actually scientists, such as Gary Null or Kent Hovind) who has a pet theory that they refuse to change or adjust on the basis of evidence, whose pet hypothesis then goes on to define everything they do in their scientific field. In Duesburg’s case, back when he started out, there was reason enough to give his hypothesis credence. He was Sure, the evidence was piling up that every single case, AIDS was caused by HIV, but his hypothesis wasn’t unthinkable. So what happened? It was tested.

The results were fairly overwhelming. In a cohort study of 715 individuals, all with similar risk behavior profiles, all 136 who developed symptoms of AIDS were in the group that had HIV-positive markers. All other factors being virtually the same, the difference was 38% vs. 0%. Unless the results were found to be falsified (they weren’t) or confounding factors were found (they weren’t), this study alone should completely destroy Duesburg’s hypothesis. And that’s not the only one. The National Institute of Allergies and Infectious Diseases, NIAID, had two different major studies in a similar time frame, the Multicenter AIDS Study and the Women’s Interagency HIV Study. The results?

In those studies, the risk of discovering an AIDS-like illness among those with HIV was 1,100 times higher than the likelihood of finding such a disease among those who were not HIV positive. From over 40,000 samples, only 16 samples ever tested lower than 200 CD4 cells per cubic mililiter of blood. This is the kind of slam-dunk, completely clear evidence that is rare in medical science. Then, in 2008, another study came out, this one examining more closely the link between various recreational drugs and CD4 and CD8 counts:

And found absolutely no effect. Of course, this was rather redundant, as a 1993 study had already shown this:

Same story - those who are HIV positive get AIDS, those who aren’t don’t, despite the same degree of risk. And of course, you also have every other virus in the genetic family of HIV - FIV, BIV, Swamp Fever, et cetera - all with the same pathology, meaning that if HIV is a conspiracy, you’ve either got one bizarre black sheep of the evolutionary family, or the vets are in on it too.
There is hardly a hypothesis in medical science today which has been more soundly refuted by the evidence than Duesburg’s. He gave up a promising career in oncology to opine on a field he was not an expert in, and once his hypothesis was examined and falsified not by some shadowy conspiracy but simply by an extremely long line of observations, he dug his heels in and did everything from adding ad-hoc explanations to the theory to flat-out accusing those who disagreed with him of conspiracy to deny the evidence. Everything except actually producing evidence of his own. That is why he is considered a crank. That is why you will not find a single scientific organization in the world which endorses him or his work. That is why he hasn’t published a paper in a peer-reviewed journal in decades.
