Does HIV cause AIDS?

Does HIV cause AIDS?

Yes, of course HIV is the cause of AIDS. There is, in my judgment, more evidence that HIV is the cause of AIDS than we have for the cause of any human disease, virtually, with perhaps the exception of a particular genetic disease where one protein abnormality like sickle cell anaemia, where you know the gene, you know the protein. You know how the protein is abnormal, and you know what that does to a red blood cell to cause the anaemia. But in terms of an infectious disease I don't know any that we have any better data. The bulk of that evidence was known by 1984 to 85. And since then it's been enormously complemented by the therapy data.
