BESURE Study: National HIV Behavioral Surveillance Study in Baltimore


The National HIV Behavioral Surveillance (NHBS) system is a CDC-funded project conducted in 21 cities in the United States, including Baltimore. The purpose is to measure HIV prevalence, HIV risk behaviors, HIV testing behaviors, and exposure to prevention services over time among persons at high risk for infection. NHBS has three cycles focusing on different groups: men who have sex with men (MSM), injection drug users (IDU), and heterosexuals at risk of HIV infection (HET). Information from NHBS guides prevention and HIV counseling and testing services in Baltimore. It also helps guide and improve overall HIV/AIDS surveillance, and provide a better understanding of trends in HIV infection in Baltimore and throughout the United States.
