Awareness and use of HIV pre-exposure prophylaxis among attendees of a seattle gay pride event and sexually transmitted disease clinic.

We surveyed a convenience sample of 215 HIV-negative men who have sex with men (MSM) recruited at a Gay Pride event and in an STD clinic about their willingness to use pre-exposure prophylaxis (PrEP). Overall, 44% reported that they would take PrEP every day if it helped prevent HIV. There was no association between sexual risk behavior and interest in taking PrEP.
