The aim of this study was to determine the prevalence of soil transmitted helminthes among primary school children. School based cross-sectional study design was employed. A total of six hundred study subjects were selected by a multistage sampling method. Fresh stool specimens were collected using clean, dry and wide mouthed labeled stool cups. It was processed by Kato-Katz technique. The data were analyzed using SPSS version 20 and p-value < 0.05 was considered statistically significant.
The overall prevalence of soil transmitted helminthes was 57 (9.5%). Hookworm was the most prevalent helminthes species isolated (4.2%) followed by A. lumbricoide (3%). The prevalence of Taenia species, T. trichiura, H. nana and E. vermicularis were; 1.2%, 0.5%, 0.7% and 0.8% respectively. The prevalence of the Soil transmitted helminthes infection was low and all cases of Soil transmitted infections in this study were with low infection intensity. This might be due to the preventive chemotherapy given to the school children.
本研究旨在确定小学生中土源性蠕虫的流行率。采用基于学校的横断面研究设计。通过多阶段抽样方法共选取了600名研究对象。使用干净、干燥且带有标签的广口便杯收集新鲜粪便样本。采用加藤厚涂片法进行处理。使用SPSS 20版对数据进行分析，p值<0.05被认为具有统计学意义。
土源性蠕虫的总体流行率为57例（9.5%）。钩虫是分离出的最常见蠕虫种类（4.2%），其次是蛔虫（3%）。绦虫属、鞭虫、微小膜壳绦虫和蛲虫的流行率分别为1.2%、0.5%、0.7%和0.8%。土源性蠕虫感染的流行率较低，本研究中所有土源性感染病例的感染强度均较低。这可能是由于对学童进行了预防性化疗。
