GONE webinar report: Malawi close to the finish line of eliminating onchocerciasis

Overview

The Malawi Onchocerciasis Control Programme began in 1984 in collaboration with the Tea Association of Malawi, initially focusing on assessing disease prevalence, infection rates, and vector identification. Following successful ivermectin trials, mass drug administration (MDA) began in 1991 in select districts and expanded over time, with the current strategy involving annual or biannual MDA in ten districts. Evaluations between 2011 and 2015 confirmed progress toward elimination, and in 2024, a national elimination mapping survey showed low prevalence (overall 0.28%). Based on these results and expert committee recommendations in 2025, Malawi will continue MDA, prioritize data analysis, and enhance entomological monitoring. Challenges remain, particularly regarding cross-border transmission with Mozambique due to shared river breeding sites and uncoordinated efforts between the two countries.
