From October 2005 to June 2006, integrated HIV biologic and behavioral surveillance (IBBS) was conducted among selected population groups in Hanoi, Quang Ninh, Hai Phong, Da Nang, Ho Chi Minh City (HCMC), An Giang, and Can Tho. The IBBS utilized community-based sampling to estimate the prevalence of HIV and other sexually transmitted infections (STI) and to provide indicators of risk behaviors and intervention exposure among most-at-risk population groups. These included female sex workers (FSWs), injecting drug users (IDUs) and men who have sex with men (MSM).
