How did the first case of the AIDS virus get contracted?

There is not such a thing as an AIDS virus. It's the HIV virus, and the title AIDS is the high viral load level of HIV infection. The question has been the subject of quite a bit of discussion. Some claim that it was from sexual contact with other species, some of the more paranoid subscribers to conspiracy theories claim that it was from a government attempt to destroy homosexuals. Pick your theory, I don't think AIDS patient #1 is talking.
