Transmission of HIV and AIDS

Transmission in Prostitutes

Prostitutes should be at grave risk of HIV/AIDS infection, but there is some evidence that they are not, unless they abuse drugs (which many do). They often have unprotected sex with many men of unknown HIV status. In places like Africa with a high fraction of men HIV-positive, this must mean that they are having unprotected sex with tens or hundreds of HIV-positive men, yet many of them are not becoming HIV-positive.
