The impact of the termination of Lymphatic Filariasis mass drug administration on Soil-transmitted Helminth prevalence in school children in Malawi

An overall resurgence in A. lumbricoides infections after LF MDA was estimated in SAC, despite ongoing annual STH PC. This suggests STH PC could not sustain the prevalence levels achieved in SAC under community-wide LF MDA. The potential role of drug resistance in this resurgence calls for urgent investigation. Understanding how this resurgence corresponds to prevalence of moderate and heavy infections should be a priority for future research.
