Background & objectives: Schistosomiasis is one of the major neglected tropical parasitic diseases caused by a group of blood-feeding worms in the genus Schistosoma. Nigeria ranks highest among all countries worldwide, however, there is a paucity of information on the prevalence of the disease in some parts of the country. Therefore, the research aims to augment available data on the prevalence of Schistosoma haematobium infection among school-aged children in ten communities in Edo state, Nigeria. Methods: A cross-sectional survey involving 400 school-aged children was conducted in 10 randomly selected communities in Akoko-Edo Local Government Area, Edo State of Nigeria between November 2016 and April 2017. Demographic data of subjects was collected using a structured questionnaire. Urine samples were collected and examined for haematuria and ova of Schistosoma haematobium using a commercially prepared reagent strip (Medi-Test Combi9TMR) and sedimentation technique respectively. Results: The prevalence of urinary schistosomiasis based on microscopic examination of the urine sediment for the ova of S. haematobium was 17.3%, while haematuria was 22.0%. Mean intensity of S. haematobium oval count ranged between 2.0-4.0/10ml of urine per community. Prevalence was higher among males (24.5%) than females (10.0%) (P<0.05), which was statistically significant. Overall, age group 7-9 years showed the highest prevalence of infection. Farming showed a strong correlation as a parent occupational risk factor in predisposing children to infection as it accounts for 73.9% of all infections. Interpretation & conclusion: Findings indicate that urinary schistosomiasis is still prevalent among school-aged children in Akoko-Edo LGA, which hinders their growth, development and cognitive abilities. Although, mass drug administration is ongoing in some of the communities, re-infection still occurs due to ignorance, occupational factors, lack of portable water and sanitary toilets.
