Community-led mapping achieved high validation rates (86.8%) and identified substantial unmet needs in digital and concealed hotspots. Routine hotspot mapping, combined with engagement with SW communities, is essential for data-driven, equitable, and adaptive HIV responses in rapidly changing contexts.en-USHIV prevention service coveragesex workoutreachvirtual hotspotmappingvalidation rateSYREXarticleArticle
