Post-Validation Surveillance District Prioritization Tool

This tool is designed to help Lymphatic Filariasis (LF) programs prioritize areas for post-validation surveillance (PVS).  The indicators used in this tool were identified by an international group of LF experts through a collaborative consensus process.  These indicators are believed to be associated with the likelihood of ongoing  or recrudescent transmission in a given area. Once completed, this tool will give LF programs a priority ranking of implementation units (IUs) to target for PVS.
