Question about sexually transmitted diseases and HIV?When STD's can only be contracted from sex and needles etc... how did these diseases first start? Like, how did the first person become infected?

Legend has it that AIDS was first contrived when a man had sex with a monkey in Africa... But thats just what I heard and I could be very wrong.

their are to many different myths but i believe it started with sharing needles maybe stemming back from the late seventies and 80's when their was a high demand of drugs

Patient 0? I don't think anyone knows for sure how these things start (except AIDS, there are theories on that). Maybe some type of mutation... viral, bacterial, etc.
