Intestinal parasitoses are among the most commonly encountered infections among school children in poor regions of the world. Up to 600 million school children are living in areas where there is high transmission of parasitic worms. Intestinal parasitic infection has been found to have a great effect on nutritional and cognitive status, school absenteeism and dropouts among school age children. This study aimed at determining the prevalence of intestinal parasites infections and associated factors among children in a rural primary school, Northwest Ethiopia.
A cross-sectional study was conducted in May 2016 among Gob Gob Primary School children. The study participants were provided with labeled stool cups to give stool specimen. The stool samples were processed via direct wet mount and formal-ether concentration techniques. A structured questionnaire was used to collect demographic data and data on factors associated with intestinal parasitic infection through face-to-face interview.
Out of the 273 school children, 84(30.8%) were infected with at least one parasite species. Higher proportion of intestinal parasitic infection was recorded for boys (38.9%), the age group 6-10 years (38.9%), children with untrimmed finger nails (36.4%) and among those whose drinking water was from a stream (56.1%). The predominant species identified were A. lumburicoides 28(33.3%), H. nana 12(14%), E. histolytica/dispar 11(13%), G. lamblia 9(11%), hookworms 7(8.3%), Taenia spp 6(7%), E. vermicularis 6(7%), T. trichuria 4(4.8%) and S. stericoralis 1(1.2%).
This study showed that intestinal parasites were prevalent among the school children in focus. Ascaris lumbricoides was the predominant species.
肠道寄生虫病是世界贫困地区学童中最常见的感染之一。多达6亿学童生活在寄生虫高发地区。已发现肠道寄生虫感染对学龄儿童的营养和认知状况、缺课和辍学有很大影响。本研究旨在确定埃塞俄比亚西北部一所农村小学儿童肠道寄生虫感染的患病率及相关因素。
2016年5月对戈布戈布小学的儿童进行了一项横断面研究。为研究参与者提供了有标签的粪便杯以采集粪便标本。粪便样本通过直接湿片法和改良加藤厚涂片法进行处理。通过面对面访谈,使用结构化问卷收集人口统计学数据和与肠道寄生虫感染相关因素的数据。
在273名学童中,84名(30.8%)至少感染了一种寄生虫。男孩(38.9%)、6至10岁年龄组(38.9%)、指甲未修剪的儿童(36.4%)以及饮用水来自溪流的儿童(56.1%)中肠道寄生虫感染比例较高。鉴定出的主要虫种为蛔虫28例(33.3%)、微小膜壳绦虫12例(14%)、溶组织内阿米巴/迪斯帕内阿米巴11例(13%)、蓝氏贾第鞭毛虫9例(11%)、钩虫7例(8.3%)、带绦虫属6例(7%)、蛲虫6例(7%)、鞭虫4例(4.8%)和粪类圆线虫1例(1.2%)。
本研究表明,所关注的学童中肠道寄生虫感染普遍存在。蛔虫是主要虫种。
