Nepal is categorized as a country facing a concentrated HIV epidemic. The National Centre for AIDS and STD Control (NCASC) has estimated that there were 39,249 PLHIV in Nepal in 2014 with adult HIV prevalence of 0.20% (NCASC, 2014).The spread of Human Immunodeficiency Virus (HIV) is concentrated among Key Affected Populations (KAPs) comprising of people who inject drugs (PWIDs), men who have sex with men (MSM), labor migrants and spouses, and Female Sex Workers (FSWs). The transmission of HIV is largely driven by KAPs and consequential health-risk behaviors. The Integrated Biological and Behavioral Surveillance (IBBS) survey is a descriptive serial cross-sectional survey conducted to monitor trends in HIV and STI prevalence and to assess behavioral information from high-risk groups. Behavioral surveillance is the systematic and ongoing collection of data about risk behaviors related to disease and health conditions, with the purpose of correlating trends in behavior with changes in disease over time.
