Formative Assessment on the Feasibility of an Integrated Biological and Behavioral Survey among Key and Vulnerable Populations in Bhutan

A cross-sectional design with qualitative and quantitative methods was used for this formative assessment that was aimed at informing the development of the IBBS survey among key populations, i.e., FSW, MSM, transgender women, Drug Users (DU), and PWID, and vulnerable populations (High-risk women—HRW, truck and taxi drivers, and uniformed services) in priority sites in Bhutan.
