From 2008 onwards, Nepal was able to meet the minimum data requirements to use Estimation and Projection Package (EPP) in a concentrated epidemic setting at national level. This includes availability of good quality HIV surveillance data, with at least three points, from at least three consistent sites amongst the populations that are at increased risk to HIV, and also have at least one data point from ANC attendees. As a result, in 2009, for the first time, the EPP software was used to generate national HIV estimates against the Workbook model used in the previous three rounds of estimates. Using a combination of EPP and Spectrum provided us not only with estimates of the current burden of HIV infections (for example, adult HIV prevalence) in the country, but also future projections that allows us to better design HIV prevention programmes and treatment, care and support interventions for people infected with and affected by HIV. One of the key outputs of this modelling is to identify key programme needs like ART needs, mothers requiring PMTCT services, etc, which guide evidence-informed planning, programming and resource allocation for interventions.
