In Haiti, a study was conducted in 2012 to assess the prevalence of HIV and condom use among sex workers. The study was funded by USAID and implemented by Population Services International (PSI) Haiti. The research aimed to provide data on the prevalence of HIV and sexual behaviors among sex workers, as well as to identify factors associated with these behaviors. The study used a cross-sectional design and measured the prevalence of HIV and sexual behaviors among sex workers in Haiti. The study found that the prevalence of HIV among sex workers was 8.4%, with varying rates across different departments. The study also found that the majority of sex workers used condoms consistently with clients, but less consistently with non-paying partners. The study identified several factors associated with HIV risk among sex workers, including lack of access to condoms, lack of knowledge about HIV prevention, and experience of violence. The study also found that sex workers who had been exposed to HIV prevention messages were more likely to use condoms consistently. The study’s findings have implications for HIV prevention programs targeting sex workers in Haiti. The results suggest that increasing access to condoms, improving knowledge about HIV prevention, and addressing violence against sex workers are critical to reducing HIV risk among this population.
