Sexual HIV/HSV-2 risk among drug users in New York City: an HIV testing and counseling intervention.

Undiagnosed and untreated sexually transmitted infections are highly prevalent among users of heroin, crack, cocaine, and amphetamines. Between 2008 and 2009, 58 heroin, cocaine, and crack users in New York City who reported unprotected vaginal and anal sex with more than one partner in the past 30 days were enrolled in an HIV testing and counseling intervention. Four weeks post intervention, increases were found for condom use and STI knowledge. Reductions were noted for safe-sex risk fatigue, number of same-and opposite-sex partners, and days when drugs were injected. Brief but intense counseling interventions can reduce HIV risk among high-risk populations.
