This is an article challenging the widely accepted theory that the Human Immunodeficiency Virus (HIV) is the cause of Acquired Immune Deficiency Syndrome (AIDS). The author argues that HIV does not meet the criteria to be considered a pathogen and that there is no direct evidence of the virus in people with AIDS. The article also questions why only a small percentage of people with HIV develop AIDS and why there is a latency period of several years before the onset of the disease. The author suggests that there may be other factors at play and that the virus-AIDS hypothesis fails to make a case for sufficiency.
