In all settings, however, the rate of heterosexual
transmission of
HIV is low. The high
rates in African Americans largely are due to heterosexual transmission, but even there it's very much a reflection of hidden homosexual exposure, injection drug use, and prior incarceration (with jail and prison time largely reflecting sex among men). Of course there are portions of white, Asian, and other population groups with high rates of HIV related to injection drug use, sex between men, etc.
