National HIV Behavioral Surveillance System
The primary purpose of the National HIV Behavioral Surveillance System (NHBS) is to conduct behavioral surveillance among a representative group of people at high risk for HIV infection in the U.S. in order to assess prevalence and trends in (1) risk behaviors for HIV infection; (2) HIV testing behaviors; and (3) exposure to, use of, and impact of HIV prevention services. The survey focuses on the three populations at highest risk: men who have sex with men, injecting drug users, and high-risk heterosexuals. The project collects information from these three populations in rotating 12-month cycles.
