The control and elimination of schistosomiasis in Nigeria with preventive chemotherapy (PC) require precise mapping of disease endemicity. We used a novel ESPEN schistosomiasis community data analysis tool developed by WHO/ESPEN to disaggregate LGA epidemiological data from 4,773 locations across Nigeria for the period 2000-2018 into ward-level endemicity data. We derived schistosomiasis endemicity for 6,188/9,684(63.9%) wards in the country. The proportion of non-endemic wards compared to the non-endemic LGAs increased from 2,533 (26.2%) to 3,320 (34.3%), and the number of endemic wards requiring PC dropped from 7,151 (73.85%) to 6,364 (65.7%). In addition, the number of persons requiring PC treatment increased from 39,652,252 to 41,196,352 individuals of which 16,478,341 (40.0%) are school-age children. The people requiring PC treatment based on new WHO treatment guidelines increased from 39,652,252 to 53,989,872 individuals, of which 18,896,462 (35.0%) are school-aged children and 35,093.410 (65.0%) are adults. These results demonstrate the usefulness of the ESPEN schistosomiasis community analysis tool for strategic planning to refocus and redirect intervention to endemic wards in need of PC towards the interruption of transmission and elimination of schistosomiasis in Nigeria.
