HIV Prevention Strategies for Sex Workers

HIV prevention among sex workers encompasses biomedical, behavioural and structural approaches designed to reduce transmission and enhance wellbeing in a population at heightened risk. Biomedical strategies centre on consistent condom provision, pre‐exposure prophylaxis (PrEP) for HIV‐negative individuals and antiretroviral therapy (ART) for those living with HIV, thereby lowering viral load to undetectable levels. Behavioural interventions include peer education, risk‐reduction counselling and skills training to promote condom negotiation and safer work practices. Structural measures address legal and policy frameworks, stigma reduction and economic empowerment to create supportive environments for service access. Community‐led outreach, drop‐in centres and mobile clinics expand testing, counselling and linkage to care, while tailored messaging and social network approaches foster trust and uptake. Together, these strategies form an integrated HIV response that combines individual protection with systemic reform—recognising that decriminalisation, stigma mitigation and collective empowerment are as crucial as medical tools in achieving sustained reductions in incidence and improving health outcomes for sex workers worldwide.

Recent studies have highlighted the impact of legal and societal factors on prevention service uptake. Analyses across multiple sub‐Saharan settings demonstrate that punitive sex work laws and intersecting stigmas correlate with higher HIV prevalence by driving sex workers underground and reducing access to condoms, testing and PrEP. Conversely, rights-affirming, decriminalised frameworks are associated with increased routine screening, greater ART adherence and stronger community solidarity. A national survey of clients in East Africa further reveals that targeted education and voluntary testing campaigns can reduce demand for unprotected encounters, underscoring the necessity of engaging both sex workers and their partners in comprehensive prevention programmes.
