BackgroundDespite encouraging declines in the overall rate of new transmission globally, HIV prevention efforts targeting individuals in the criminal legal system continue to significantly lag behind rates identified in the general population. Prevention efforts targeting this group worldwide remain geographically uneven and differ across the continuum of legal system involvement (diversion, arrests, community supervision, and post-release), which is attributed to social, structural, and systemic barriers. These gaps are noted to disproportionately impact minoritized and other transmission-burdened populations within the criminal legal system (e.g., men who have sex with men).ObjectiveGiven these challenges, this literature review examines HIV prevention efforts targeting individuals in the criminal legal system across the globe.MethodsThis review identifies current reach and gaps in prevention care and proposes strategies for improvement.ResultsRecommendations include updating and utilizing long-term platforms for sustained HIV prevention interventions, developing a global compendium for regions outside the U.S., enhancing targeted interventions in high-risk areas, and integrating HIV prevention with other health services while addressing stigma.ConclusionsThese actions are critical for ensuring that interventions remain up-to-date, sustainable, and culturally responsive, effectively addressing the unique needs of diverse populations and criminal legal system contexts. These measures are also vital for meeting the U.N. 95-95-95 targets for HIV testing, treatment, and viral suppression, ultimately contributing to the goal of ending the HIV epidemic among this high-need population.
