A retrospective cohort study was conducted. Interviews were conducted to identify learners who have been passing bloody urines. We collected urine samples from learners in each grade using random sampling and for microscopic analysis. An environmental analysis was conducted, and water samples were from sites along the river. A case of Schistosomiasis was defined as any learner with blood-stained urine and laboratory confirmed microscopic Schistosoma ova in the urine at Mupini Village, June – August 2022. We computed descriptive statistical analysis, proportions and averages.
