However, when it was discovered that AIDS did not only occure in homosexual men, these gradually fell out of use. The [[Centers for Disease Control]] noticed an increase in requests for drugs needed to treat this illness and launched an epidemiological investigation.   

Although the first cases of the disease probably go back to the 1950s, the epidemic was not recognized until the early 1980s [http://www.avert.org/his81_86.htm].  The early epidemic occurred in two main branches; in the US and other developed countries, and in sub-Saharan Africa.  In the US, the early epidemic was primarily spread by homosexual sex, intravenous drug use, and blood transfusions (prior to the introduction of testing).  In Africa, transmission was almost exclusively by heterosexual sex.  Currently, most new infections worldwide are spread by promiscuous heterosexual sex and prostitution.
