The idea that this is a lab-created virus run amuck is not new. I heard the entire WHO and Military theory 10 or more years ago. It was bad science.
Viruses do transfer from species to species.
There are no documented cases anywhere that AIDS is a contagious airborne virus. This may be hard to accept, but sometimes something is not documented not because of a cover-up, but simply because there is no evidence of it actually occuring. Never heard of a saliva test for AIDS before this posting. Perhaps I'm ignorant to this one. If so, I apologize.
