What the hell kind of racist crap is this? Transmission of the HIV virus has no relation to race. The fact that the virus appears to have originated in Africa is a complete irrelevancy. HIV is transmitted through exchange of fluids; therefore the most common method of transmission is sexual. However, a person may also become infected by using a hypodermic needle which has been previously used by an infected person. That is why incidence of AIDS and HIV infection is so prevalent among intravenous drug users. A third method of transmission is congenital, i.e. a nursing mother who has the infection will almost certainly pass it on to her infant.
At any rate, none of this has anything whatever to do with race.
What other silly questions do you have?
