World Health Organization estimates one-fourth of world's population harbors one or more intestinal parasites. Intestinal parasites are among the most common infections of school age children causing-nutritional deficiency, chronic dysentery, rectal prolapse, poor weight gains, retarded growth and mental retardation.
The stool samples were collected from school going children and examined for intestinal parasite by normal saline wet mount, formalin ether sedimentation technique was performed for the concentration.
Among 360 school age students, the prevalence of intestinal parasite was found 40%. Among the positive cases of which 60% were female. It was observed that the rate of parasitic infection among positive cases, Newar was 35(36.84%), Chettri 31(32.97%) and Brahmin and others 29(33.72%) respectively. The study detects an association between intestinal parasitic infection and drinking tape water.
The findings of this study showed that intestinal parasitic infections remain prevalent in the study area. The high prevalence of parasitic infections seems directly related to the unhygienic living conditions. This strongly indicates a need for intervention measures likely-to take up sustained health education, provision of safe drinking water and improvement in environmental sanitation and to provide the school student with health education.
世界卫生组织估计，世界四分之一的人口感染了一种或多种肠道寄生虫。肠道寄生虫是学龄儿童最常见的感染之一，可导致营养缺乏、慢性痢疾、直肠脱垂、体重增加缓慢、生长发育迟缓以及智力发育迟缓。
从学龄儿童中采集粪便样本，通过生理盐水湿片法检查肠道寄生虫，并采用福尔马林乙醚沉淀技术进行浓缩。
在360名学龄学生中，肠道寄生虫感染率为40%。在阳性病例中，60%为女性。观察发现，在阳性病例中，尼瓦尔族的寄生虫感染率为35（36.84%），切特里族为31（32.97%），婆罗门及其他族为29（33.72%）。该研究发现肠道寄生虫感染与饮用自来水之间存在关联。
本研究结果表明，肠道寄生虫感染在研究区域仍然普遍。寄生虫感染的高发生率似乎与不卫生的生活条件直接相关。这强烈表明需要采取干预措施，可能包括开展持续的健康教育、提供安全饮用水、改善环境卫生，并为在校学生提供健康教育。
