Community-based HIV/AIDS interventions have been implemented in Nairobi to address high-risk areas affected by the disease. A mixed-methods approach combining quantitative surveys with qualitative focus group discussions was employed across Nairobi's high-risk neighborhoods. During the study, it was observed that participation in intervention programmes increased by 30% among community members compared to baseline levels. The findings suggest that tailored community engagement strategies are crucial for the success of HIV/AIDS interventions in these areas. Healthcare providers and policymakers should prioritise training community leaders and integrating health education into daily life practices.
