This cross-sectional study was conducted to investigate the prevalence of intestinal parasites among primary school children in Northern Jordan. Stool specimens were collected from 1100 children of both sexes from urban and rural schools. A questionnaire covering relevant informations was completed for each child. Wet mount preparation, formaline-ether concentration technique, and trichrome stain were prepared for the recovery and identification of parasites. Giardia lamblia was observed in 396 (36%) of the stool specimens examined. The infection rates were higher in the younger age group where several of them had diarrhoea and reported variable symptoms. The infection rates declined with age and children were asymptomatic. Rates were higher in children from the rural areas, from low income families, and it was higher in boys than girls. Contaminated drinking water is suspected to be the major potential source of infection. The importance of the asymptomatic cases and the epidemiological factors contributing to the transmission in these areas are discussed.
本横断面研究旨在调查约旦北部小学生肠道寄生虫的流行情况。从城市和农村学校的1100名男女儿童中采集粪便标本。为每个儿童填写了一份涵盖相关信息的问卷。采用湿片制备、甲醛乙醚浓缩技术和三色染色法进行寄生虫的回收和鉴定。在所检查的396份（36%）粪便标本中观察到蓝氏贾第鞭毛虫。感染率在年龄较小的组中较高，其中一些儿童患有腹泻并报告有不同症状。感染率随年龄下降，儿童无症状。农村地区、低收入家庭儿童的感染率较高，男孩的感染率高于女孩。受污染的饮用水被怀疑是主要的潜在感染源。讨论了无症状病例的重要性以及这些地区导致传播的流行病学因素。
