The purpose of the model is to understand the sources of new HIV infections for better programme planning and support of programme pillars. The model results, together with existing epidemiological data and the conclusions of recently completed studies on the factors driving Sierra Leone’s HIV epidemic are compared with data on HIV funding allocations, to derive recommendations for strengthening Sierra Leone’s HIV prevention response and also for improving HIV prevention based on evidence on what works to prevent new infections.
