<p>We conducted a cross sectional study at school. We reviewed Out-patient register at Otjimuhaka clinic. We screened learners using urine reagent strips. We collected urine and blood samples randomly from learners with hematuria, for laboratory investigations. Learners with hematuria were treated with Praziquantel tablets. A case was any learner at Otjimuhaka Primary School with hematuria, by urine reagent strip. We interviewed staff and community members.</p>
