登封市2016年土源性线虫流行现状调查

Survey of current epidemiological situation of soil-transmitted nematodes in Dengfeng city in 2016

目的:调查登封市2016年土源性线虫的流行现状。方法:抽取登封市东、西、南、北、中5个乡镇(办事处)的1 051名群众作为观察对象。采用改良加藤厚涂片法检测土源性线虫;对3~9周岁的儿童采用透明胶纸肛拭法检测蛲虫卵。统计土源性线虫感染率,分析性别、年龄和地区对感染率的影响。结果:登封市土源性线虫总感染率为1.33%(14/1 051),均为蛲虫感染;男女感染率差异无统计学意义(P>0.05);儿童感染率明显大于成人(P<0.05);不同片区感染率差异有统计学意义(P<0.05)。结论:登封市不同地区土源性线虫感染率有较大差异,儿童仍是蛲虫感染的高危人群。

Objective： To survey the current epidemiological situation of soil-transmitted nematodes disease in Dengfeng cityin 2016. Methods： 1051 people of five villages of Dengfeng city （ east, west, south, north and the middle） were chosen as the objects. The soil-transmitted nematodes were detected by the modified Kato-Katz method, and the pinworm eggs were detected with thecellophane and swab for the children of 3-9 years old. The soil-transmitted nematodes infection rate was statistically analyzed, and theeffects of sex, age and districts were analyzed. Results： The total infection rate of the soil-transmitted nematodes was 1. 33% （14 /1051）, which was caused by the pinworm. The infection rate between male and female was not statistically significant （P〉0. 05）;however, those among different districts were statistically significant （P〈0. 05）. Further, the children＇s infection rate was significantlyhigher than that of the adult （P〈0. 05）. Conclusions： There are great differences in the soil-transmitted nematodes infection rate among different districts of Dengfeng city, and the low age groups are still at a high risk.
