Listen to the 27 minutes or so of the audio clip and discover the journey the aids virus has apparently taken since it allegedly jumped from an SIV to an HIV about 1908. It was very difficult to understand just what happened, but this is what I interpreted.
The HIV-Aids virus happened when an African man hunted a chimpanzee for meat about 1908. Little did he know that the chimp had a simian immune virus which the hunter contracted when cutting himself while butchering the chimp. The chimp had contracted the virus when eating monkeys. The hunter may have passed on the new HIV when visiting prostitutes in town.
The HIV could have been contracted in the US as early as 1969. A patient called Patient Zero, but who was most likely not the original patient zero,was a French Canadian homosexual who moved frequently between New York, San Francisco and other cities. It was believed that in the end he knew he had a terminal disease and continued to infect his contacts.
