Abstract

The U.S. agency for international development (USAID) Neglected Tropical Disease(NTD)Control Program supports the implementation of Mass Drug Administration (MDA) in 12 developing countries to control five neglected tropical diseases: Lymphatic Filariasis, Onchocerciasis, Soil Transmitted Helminths, Schistosomiasis, and Trachoma. The objective of the Post MDA Survey is to validate the accuracy of the country reported MDA coverage rates. There are unique challenges to designing and implementing household surveys in developing countries. We will present the design effect and the precision of the estimated drug coverage rates of multi-stage surveys from one country: Niger. We will identify effective sampling methodology for program evaluation in developing countries. Specifically, we will focus on the stratification and clustering strategies and identify effective methods to reduce variance
