A 3-month investigation by the scientific journal Science evaluated claims made by UC-Berkeley virologist Peter Duesberg and his supporters, who continue to argue that HIV is not the cause of AIDS.

The four-part evaluation is preceded by an introductory piece entitled The Duesberg Phenomenon which also provides the conclusions of the Science evaluation:

• In hemophiliacs (the group Duesberg acknowledges provides the best test case for the HIV hypothesis) there is abundant evidence that HIV causes disease and death.
• According to some AIDS researchers, HIV now fulfills the classic postulates of disease causation established by Robert Koch.
• The AIDS epidemic in Thailand, which Duesberg has cited as confirmation of his theories, seems instead to confirm the role of HIV.
• AZT and illicit drugs, which Duesberg argues can cause AIDS, don't cause the immune deficiency characteristic of that disease.

Reviewing The Data (Parts I - IV):

1. Duesberg and Critics Agree: Hemophilia Is the Best Test
2. Fulfilling Koch's Postulates
3. The Epidemic in Thailand
4. Could Drugs, Rather Than a Virus, Be the Cause of AIDS?
