目的了解武汉市14岁以下儿童土源性线虫感染现状,评价防治效果。方法在全市抽取8个区,中心城区和新城区各4个,每区抽取初中、小学、幼儿园各1所,采集14岁以下各年龄儿童粪便标本,采用改良加藤厚涂片法(Kato-Katz法),一粪三检,检测钩虫、蛔虫、鞭虫及其他寄生虫虫卵,计算各虫种感染率和感染度(每克粪便中虫卵数,EPG)。结果全市共检测1 856人,检出蛔虫感染2人,均为轻度感染(EPG分别为48,600),蛔虫感染率0.11%,未检出钩虫、鞭虫等其他土源性线虫感染者。结论武汉市14岁以下儿童土源性线虫感染率较低,健康教育措施起到了重要作用。
Objective To understand the status of soil-borne nematode infection in children under 14 years old in Wuhan and to evaluate the control effect.

Stool samples from children under 14 years of age were collected and analyzed by Kato-Katz Method), a fecal three seizures, detection of hookworm, roundworm, whipworm and other parasite eggs, calculate the infection rate and the degree of infection of each species (number of eggs per gram of feces, EPG). Results A total of 1 856 people were detected in the city. Two people were found as roundworm infection, with mild infection (EPG 48,600, respectively) and roundworm infection rate 0.11%. Other hookworm, whipworm and other soil-borne nematode infections were not detected.
