Germ theory of disease fails Virus-AIDS hypothesis
... The clinical threshold of viral disease is about 10^9-12 infected cells, depending on the infected tissue. Accordingly, a single blood-borne virus, like HIV or mononucleosis virus, can cause disease by infecting about 10^12 blood cells (1/5 of the total) in only 6 days. 10^12 infected cells = 1 (inf ...
