Sierra Leone has stopped mass drug administration (MDA) for lymphatic filariasis in 75% of endemic districts in the country following interruption of transmission of the causative parasite in 12 districts as of FY21 (October 2020 – September 2021). Prevalence of infection has been reduced significantly in the remaining four districts due to ongoing MDA.
Sierra Leone will conduct a schistosomiasis/soil-transmitted helminthiasis (SCH/STH) impact assessment in nine districts in 2022 following up to ten rounds of high coverage MDA. Data from this survey will enable the country to consider moving to sub-district MDA in 2023.
