To determined both prevalence and intensity of Schistosoma mansoni infections among schoolchildren attending primary schools in Jimma town, an urban setting, Southwest, Ethiopia.
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 = 31.587, P value = 0.001; 95% CI), and the infection rate increased as a function of age (χ = 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.
确定在埃塞俄比亚西南部城市吉马镇的小学生中曼氏血吸虫感染的流行率和感染强度。
曼氏血吸虫感染的流行率为8.4%。在所有17所学校均发现了曼氏血吸虫感染，但学校感染率在1.7%至26.7%之间。这种流行率的差异可以通过学校与穿过该镇的河流以及学校附近水体的距离来解释。与女孩相比，男孩感染率更高（χ = 31.587，P值 = 0.001；95%置信区间），并且感染率随年龄增长而增加（χ = 21.187；P值 = 0.001；95%置信区间）。大多数感染强度为低强度（57%），每克粪便中的平均虫卵数为17个。基于流行率（8.4%），吉马镇的学童被认为由曼氏血吸虫引起的发病风险较低（根据世界卫生组织阈值，流行率≤10%），为此建议每3年开展一次大规模药物驱虫，同时应辅以健康信息，以提高对血吸虫病传播的认识。男学生比女学生感染率更高，且大多数感染强度为低强度。
