HIV Prevention Strategies in Diverse Contexts
Summary
HIV prevention underpins global efforts to curb incidence and achieve epidemic control through a range of strategies tailored to diverse epidemic, social and cultural contexts. Biomedical approaches—most notably pre-exposure prophylaxis and antiretroviral therapy—have transformed the prevention landscape by reducing transmission risk at individual and population levels. Behavioural interventions such as peer education, condom provision and targeted communication continue to play a central role, often delivered through community-led networks that empower key populations: men who have sex with men, sex workers, people who inject drugs and transgender communities. Structural interventions address social determinants of health by tackling stigma, discrimination, legal barriers and gender norms that heighten vulnerability. Implementation science frameworks guide the optimisation of combination prevention packages, ensuring interventions are accessible, acceptable and sustainable across low-, middle- and high-income settings. Recent advances include long-acting injectable regimens, topical microbicides and digital health platforms that enable remote support, risk monitoring and adherence reinforcement. Holistic models emphasise integration of prevention with sexual and reproductive health, mental health and substance-use services, reflecting an understanding of intersecting vulnerabilities and the need for equity-oriented, context-specific responses.

HIV Prevention Strategies in Diverse Contexts publication trend
The graph below shows the total number of articles in hiv prevention strategies in diverse contexts across all publications each year (not limited to Nature Index journals).
Technical terms
Pre-exposure prophylaxis (PrEP): Administration of antiretroviral medication to HIV-negative individuals to prevent acquisition.
Antiretroviral therapy (ART): Combination drug regimens that suppress viral replication in people living with HIV.
Key populations: Groups disproportionately affected by HIV due to social, legal or structural factors, including men who have sex with men, sex workers, people who inject drugs and transgender individuals.
Structural interventions: Programmes that modify social, legal or economic environments to reduce HIV vulnerability.
Implementation science: Discipline that studies methods to promote uptake of research findings into routine policy and practice.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
