Another way that SIV was transferred to humans was hunting of the monkeys (http://unhavas.hartford.edu). Hunting monkeys often caused blood to get on the hunters and therefore increasing the chances of them getting it. This doesn't bode well because there may well be a continuing transfer of the disease from monkeys to humans which means the disease could never really die out. .
In the late 1970's there was the beginning of gay uprising. Finally homosexual were starting to come out and live their lives and demand respect. The uprisings were the largest in New York , San Francisco, and Los Angeles (http://unhavas.harford.edu). This new found freedom caused everyone to take advantage that they didn't have to hide anymore. From that time forward gay sexuality was in the open. As the rate of casual sex skyrocketed, so did the rates of sexually transmitted diseases. Gonorrhea reports tripled and syphilis reports quadrupled between 1965-1975 (http://unhavax.harford.edu). To give and example of how horrific the spread of STD's was getting this quote was taken from Michael Callen, "I calculated that since becoming sexually active in 1973, I had racked up more than three thousand different sexual partners in bathhouses, back rooms, meat racks, and tearooms. As a consequence I also had the following sexually transmitted diseases, many more than once: hepatitis A, hepatitis B, non-A/B hepatitis; herpes simplex Types I and II; venereal warts; giardia lamblia and entamoeba histolytica; shigella flexneri and salmonella; syphilis; gonorrhea; nonspecific urethritis; chlamydia; cytomegalovirus (CMV), and Epstein-Barr virus (EBV) mononucleosis; and eventually cryptosporidiosis. " (Surviving AIDS) With this new liberated sense many bathhouses were created in the New York City area along with San Francisco and Los Angeles. Bathhouses were places where homosexual men would go and engage in different sexual acts with other men.
