The global HIV epidemics among sex workers

Since the beginning of the epidemic sex workers have experienced a heightened burden of HIV across settings, despite their higher levels of HIV protective behaviors (UNAIDS, 2009). Unfairly, sex workers have often been framed as 'vectors of disease' and 'core transmitters' rather than workers and human beings with rights in terms of HIV prevention and beyond. By gaining a deeper understanding of the epidemiologic and broader policy and social context within which sex work is set one begins to quickly gain a sense of the complex backdrop for increased risk to HIV among sex workers. This backdrop includes the critical role of stigma, discrimination and violence faced by sex workers, as well as, the importance of community empowerment and mobilization among sex workers to address these regressive forces. The eight country case studies work to highlight the experiences of diverse populations of and contexts for sex work across settings. Given the limited epidemiologic and intervention evaluation data available among male and transgender sex workers, however, our collaborative team (Johns Hopkins University, or JHU, World Bank, United Nations Population Fund (UNFPA), and Global Network of Sex Work Projects, or NSWP) determined that the systematic review, mathematical modeling and cost-effective analyses would focus on female sex workers. Throughout the process of this analysis as a whole, the participation of sex worker perspectives and sex worker organizations such as NSWP and their regional partners has been critical by providing documents and resources, input and consultation throughout the analytical process.
