As of 2007, it was estimated that there are 33,000,000 people living with HIV. That is equal to the population of Canada.

Science now suspects that AIDS first entered the human population somewhere between 1884 and 1924. There is an excellent article via this link: http://www.avert.org/origin-aids-hiv.htm

To say that HIV is a 'gay' disease is to ignore the research. Period.
