National HIV​ Behavioral Surveillance System

The National HIV Behavioral Surveillance (NHBS) System is a national health survey that collects information on sexual risk, drug use, HIV testing behaviors, and HIV seroprevalence from populations at highest risk for HIV infection—men who have sex with men, people who inject drugs and  low-income heterosexual people. NHBS collects data from these populations each year on a rotating basis. NHBS is designed, coordinated, and funded by the Centers for Disease Control and Prevention (CDC). San Diego County is one of approximately 20 areas across the nation currently participating in NHBS, with data collection conducted by the California Department of Public Health, Office of AIDS with assistance from Family Health Centers of San Diego. In California, Los Angeles and San Francisco counties also conduct NHBS through the local health departments.​
