The National HIV Behavioral Surveillance System (NHBS) collects HIV prevalence and risk behavior data from three populations at high risk for HIV infection: men who have sex with men, injecting drug users, and heterosexuals at increased risk for HIV infection. This report summarizes data from the second NHBS data collection cycle among heterosexuals at increased risk for HIV, which was conducted during June–December 2010.
