I don't know if AIDS was man-made or not, but I was reading an essay a few days ago, and it mentioned that the AIDS virus may have mutated from one that had infected monkeys. Being that the AIDS virus doesn't kill the host immediately and people with HIV can live for years while contagious before finally developing full blown AIDS and dying, it made spreading the virus easier. There are stories of people like Gaetan Dugas, who some claimed was patient zero, having like 2500 sexual partners in his lifetime... each person that ends up infected by him can go and infect others, and it just keeps on repeating and spreading. If someone gets herpes or some other STD and gets a rash, they'll most likely go to the doctor to see what is going on. But with HIV, they may not even know they are infected so they go on doing whatever they've been doing.
