EPP: Estimation and Projection Package

The Estimation and Projection Package (EPP) is used to estimate and project adult HIV prevalence from surveillance data.

The input to EPP is surveillance data from various sites and years showing HIV prevalence among pregnant women. EPP is used to fit a simple epidemic model to data from urban and rural sites. The prevalence projection produced by EPP can be transferred to Spectrum to calculate the number of people infected, AIDS cases, AIDS-related deaths, etc. The EPP model and manual in English, French, Spanish and Russian can be downloaded from the UNAIDS website.
