目的了解福建省人体肠道线虫的流行现状。方法采用分层整群随机抽样的方法,对13个中签县市39个村(点)进行调查。应用Kato-Katz涂片法,检查粪便中肠道线虫卵;胶带纸肛拭法,检查12岁以下儿童的蛲虫感染。结果粪检20 195人,感染者7 272人,总感染率为36．01％。其中,男性感染率34．39％,女性感染率37．53％;蛔虫、钩虫、鞭虫感染率分别为9．55％、19．73％与11．48％,蛲虫为22．06％(817／3703)。年龄组以60～65岁组感染率最高占48．98％,职业分布以农民最高占41．56％,地区分布以闽北片区的凹头村最高占 79．09％。结论各地区、各种寄生虫感染率、感染度呈总体下降趋势,但各地起伏较大,部分县市钩虫感染率居高不下,肠道线虫感染仍然是当前农村地区普遍存在的公共卫生问题之一。
Objective To understand the prevalence of human intestinal nematode in Fujian Province. Methods A stratified cluster random sampling method was used to investigate 39 villages (spots) in 13 Zhongbian counties. The Kato-Katz smear method was used to examine intestinal nematode eggs in the stool; anal tape was used to examine pinworm infections in children under 12 years of age. Results 20 195 fecal seizures, 7 272 people infected, the total infection rate was 36.01%. Among them, the infection rate of males was 34.39% and the infection rate of females was 37.53%. The infection rates of roundworm, hookworm and whipworm were 9.55%, 19.73% and 11.48%, respectively, and the infection rate was 22.06% (817/3703). In the age group, the highest infection rate was 48.98% in the group of 60-65 years old, occupational distribution was 41.56% of the peasants, and the highest in the concave village in the northern Fujian was 79.09%. Conclusions The prevalence and infectivity of various parasites in various regions and regions are generally declining, but fluctuant in all parts of the country. The infection rate of hookworm in some counties and cities is still high. The infection of intestinal nematodes is still a common public health problem in rural areas at present one.
