Results from the HIV/STI Integrated Biological and Behavioral Surveillance in Vietnam: Round II - 2009

From June 2009 to February 2010, Vietnam’s second round of integrated HIV/STI biological and behavioral surveillance (IBBS) was conducted among select population groups in Hanoi, Hai Phong, Quang Ninh, Ho Chi Minh City, Can Tho, An Giang, Da Nang, Nghe An, Yen Bai, Dong Nai, Dien Bien and Lao Cai. 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 populations (MARP). These included injecting drug users (IDU), female sex workers (FSW), and men who have sex with men (MSM).
