HIV/AIDS remains a significant public health concern in Nairobi slums, where community engagement is crucial for effective prevention efforts. A mixed-methods approach combining quantitative data from surveys and qualitative insights through interviews to evaluate community engagement levels and effectiveness. Among participants, there was a significant increase (p < .05) in HIV knowledge awareness post-social media intervention, with an average of 78% improvement across the study group. Community participation via social media platforms can significantly enhance HIV prevention efforts in Nairobi slums; further research is warranted to refine strategies. Healthcare providers should integrate tailored social media campaigns into their prevention programmes, focusing on youth demographics with higher engagement rates.
