OBJECTIVE: To determined both prevalence and intensity of Schistosoma mansoni infections among schoolchildren attending primary schools in Jimma town, an urban setting, Southwest, Ethiopia.
RESULTS: The prevalence of S. mansoni infections was 8.4%. S. mansoni infections were found in all 17 schools, but the school prevalence ranged from 1.7 to 26.7%. This variation in prevalence could be explained by the proximity of the schools to the river crossing the town and water bodies near the schools. Boys were more infected compared to girls (χ 2 = 31.587, P value = 0.001; 95% CI), and the infection rate increased as a function of age (χ 2 = 21.187; P value = 0.001; 95 %CI). The majority of the infection intensities were of low intensity (57%), the mean number of eggs per stool equal to 17 eggs per gram of stool. Based on the prevalence (8.4%) school children in Jimma Town is considered as a low risk of morbidity caused by S. mansoni (prevalence ≤ 10% according to WHO threshold), for which it is recommended to implement MDA once every 3 years which should be supplemented with health information to create awareness about Schistosomiasis transmission. Male students were more infected than females with majority of the infection intensity were low.
