The role of body fluids in the transmission of infections is now well-known. Intimate contact between males and females during sexual intercourse has been held responsible for transmitting HIV/AIDS.

HIV/AIDS almost resulted in stigmatising African Americans who were most affected when the epidemic started and even now. Other racial minorities were also affected. It was largely due to male-to-male sexual contact among both Africans and Hispanics. Heterosexual sexual contact was only secondary but it was the primary factor for infection among females. Such a racial trend led to stigmatisation and even discrimination of Blacks and commercial sex workers. However, further progress of the disease was somehow contained due to a well-organised campaign, which included the use of condoms during sex.
