BACKGROUND Intestinal parasitosis is one of the commonly perceived serious problems often observed in children leading to high mortality. The objective of the study was to identify the intestinal parasites and study their prevalence in the two mostly disadvantaged communities (Musahar and Chepang) of Nepal. METHODS This was a cross-sectional study conducted in the Musahar and Chepang communities of Nepal from April to October 2019. A total of 205 random stool samples were collected in dry, clean and screw-capped plastic containers and mixed with 2.5% potassium dichromate solution. A pre-structured questionnaire was used to collect data on predisposing factors. The laboratory examination of the stool samples was done by direct microscopy and further confirmed by concentration methods (formalin ether sedimentation technique and flotation technique using Sheather's sugar solution), and modified acid-fast staining. Detection of eggs of Enterobius vermicularis was done by cellophane tape method. RESULTS The overall prevalence of intestinal parasitic infection was found to be 36.6%, with a similar prevalence in the Chepangs (39.8%) and in the Musahars (33.3%) (P > 0.05). The most predominant helminth was Ascaris lumbricoides (15.6%), while the most prevalent protozoan was Entamoeba histolytica/dispar (5.4%). The study also assessed a significant association between the prevalence of parasites with socio-demographic factors, types of drinking water consumption and sanitation habits of the people (P < 0.05). CONCLUSION The findings of the study suggest a need for formulating effective preventive and control strategies against intestinal parasitic infections along with the continuity of mass deworming program.

尼泊尔 Makwanpur 和 Nawalparasi 地区 Chepang 和 Musahar 社区居民的肠道寄生虫病。

背景肠寄生虫病是儿童中经常观察到的普遍认为的严重问题之一，导致高死亡率。该研究的目的是确定肠道寄生虫并研究它们在尼泊尔两个最贫困的社区（Musahar 和 Chepang）中的流行情况。方法 这是一项横断面研究，于 2019 年 4 月至 10 月在尼泊尔的穆萨哈尔和切邦社区进行。总共 205 份随机粪便样本被收集在干燥、清洁和螺旋盖的塑料容器中，并与 2.5% 的重铬酸钾溶液混合. 使用预先结构化的问卷来收集有关易感因素的数据。粪便样本的实验室检查通过直接显微镜检查进行，并通过浓缩方法（福尔马林醚沉降技术和使用希瑟糖溶液的浮选技术）和改良的抗酸染色进一步确认。蠕虫卵的检测采用玻璃纸胶带法。结果 肠道寄生虫感染的总体流行率为 36.6%，与 Chepangs (39.8%) 和 Musahars (33.3%) 的流行率相似（P > 0.05）。最主要的蠕虫是蛔虫 (15.6%)，而最普遍的原生动物是溶组织内阿米巴/dispar (5.4%)。该研究还评估了寄生虫流行与社会人口因素之间的显着关联，人们的饮水消费类型和卫生习惯（P < 0.05）。结论 该研究的结果表明，需要制定有效的预防和控制肠道寄生虫感染的策略以及大规模驱虫计划的连续性。
