Improving Mass Drug Administration After Pre-Transmission Assessment Survey (Pre-TAS) Failure

Nepal has been implementing Mass Drug Administration (MDA) program since 2003. The program was initiated in all 75 districts in 2013 and later in 2017, it was discontinued in more than half of the districts. Nepal is one of the first countries in the global program to achieve 100% geographical coverage, reaching all 63 districts out of 77 districts with MDA. About 48 out of 63 have stopped MDA and are on post-MDA surveillance. The remaining 15 districts have failed the pre-TAS/TAS at least once. This study gathers insights into factors associated with MDA coverage and compliance. This study evaluates new program changes on the effectiveness of MDA for Lymphatic Filariasis (LF) in two districts of Nepal that have repeatedly failed pre-TAS surveys over more than 10 years. This study also evaluates changes to MDA caused by the COVID-19 pandemic in 2021.
