Lessons Learned From the Implementation of HIV Biological-Behavioral Surveys of Key Populations in the Caribbean.

In the Caribbean region, HIV prevalence is high among key population (KP) groups, such as sex workers and men who have sex with men. However, there is a lack of high-quality, population-level data estimating HIV prevalence and population sizes of KPs. The President's Emergency Plan for AIDS Relief has funded and completed five bio-behavioral surveillance (BBS) surveys using respondent-driven sampling methodology to target KP in the English-speaking Caribbean region.
