The Epidemiology of HIV Among Sex Workers Around the World: Implications for Research, Programmes, and Policy

Excerpt

Globally, sex workers of all genders and identities continue to face disproportionately high burdens of HIV, demonstrating the need for programmes better tailoring services to their unmet needs. The reasons for this high burden are complex, intersecting across behavioural, social, and structural realities experienced by sex workers. Here, we build on systematic reviews of HIV among sex workers and case studies rooted in sex workers’ lived experience to describe: (1) the global HIV burden among sex workers; (2) the factors and determinants that influence the HIV burden; (3) intervention coverage and gaps to reduce HIV-related inequities faced by sex workers, over the past decade.

Sex workers living with HIV have not benefited enough from significant increases in HIV treatment among the general population. Engagement in this HIV treatment cascade is hindered by structural factors including stigma, migration, policing, criminalisation, and violence, as well as substance use, which present increasingly concurrent risks with HIV among sex workers.

Emerging biomedical HIV prevention innovations exist to support the health and human rights of sex workers and reduce onward transmission risk, but persistent data gaps remain, and should be addressed via community-driven implementation research. Epidemiologic research engaging sex workers who are cismen and transgender persons is similarly crucial. Community empowerment approaches have reduced the odds of HIV infection, highlighting the case for greater investments in structural interventions. These investments, combined with filling data gaps and national action towards sex work decriminalisation alongside legal protections, are critical to achieving reductions in sex workers’ HIV burden.
