National HIV Behavioral Surveillance (NHBS)

The National HIV Behavioral Surveillance (NHBS) is a multisite project funded by the Centers for Disease Control and Prevention (CDC). NHBS was established to monitor selected behaviors and use of prevention services among populations overburdened with HIV infection. NHBS operates through activities designed to monitor HIV risk behaviors to assist in prevention education, service initiatives, and allocation of prevention resources. Nationally, data is collected in 22 metropolitan areas that have the highest prevalence of HIV cases.

Why is NHBS Important?

Case surveillance provides basic information about people who have tested positive for HIV. Behavioral surveillance provides information for those who are at high risk but not yet infected. This helps to better anticipate the populations in which HIV rates are likely to increase in the future. NHBS informs decisions about where researchers and practitioners should focus resources for prevention efforts. At the individual level, participants can benefit from HIV prevention counseling, knowledge of HIV status, and referrals for additional HIV risk information and care.
