Methodology – Understanding the HIV estimates
Modelled HIV estimates are created by country teams using UNAIDS-supported software. The country teams are comprised primarily of epidemiologists, demographers, monitoring and evaluation specialists and technical partners. Country-submitted files are reviewed at UNAIDS, and selected HIV service data contained in the files are reviewed and validated in partnership with WHO and UNICEF. UNAIDS review aims to ensure comparability of results across regions, countries and over time.
