HIV prevalence was found to increase in specific regions of Sierra Leone from 2008 to 2019, highlighting significant geographic disparities.
Prevalence rates recorded were 1.5% in 2008, 1.3% in 2013, and 1.7% in 2019, indicating small fluctuations despite regional differences in trends.
The assessment of spatial distribution using Moran’s I statistic revealed significant hotspots for HIV prevalence in specific districts like Kono and Koinadugu.
Predictors such as age 15-19, urban residence, and lack of formal education were identified through geographically weighted regression, suggesting targeted intervention needs.
