宁海县学龄前儿童蛲虫感染现况调查及监测效果评价

Infection status of Enterobius vermicularis of preschoolers and evaluation of control effect in Ninghai

目的：研究宁海县学龄前儿童蛲虫感染现况,评价监测效果。方法：2011-2015年每年随机抽取5个镇乡幼儿园的入园儿童（3岁～6岁）,采用肛周粘贴透明胶纸法进行检测,对搜集的资料进行统计分析。结果：2011-2015年共监测入园儿童7 125名,不同年度感染率差异无统计学意义（χ2=6.003,P=0.199）,儿童蛲虫总体感染率为1.68%,男、女童平均感染率为1.62%、1.77%,差异无统计学意义（χ2=0.231,P=0.631）;蛲虫感染地区分布广泛;不同年龄组儿童蛲虫感染率差异有统计学意义（χ2=60.097,P=0.000）,高年龄组感染率最高;公办幼儿园蛲虫感染率低于民办幼儿园（χ2=7.151,P=0.007）。结论：宁海县学龄前儿童蛲虫感染普遍,监测防治成果显著,感染率处于较低水平,但仍需巩固防治效果。

Objective To study the infection status of Enterobius vermicularis of preschoolers and evaluate its control effect.Methods We analyzed the data about the infection of Enterobius vermicularis of preschoolers examined with adhesive cellophane anal swabs which were collected from 2011 to 2015.Results A total of 7125 children were examined from 2011 to 2015.The average infection rate was 1.68%,and the infection rates of male and female children were1.62% and 1.77%.The difference between them was not significant（χ2=0.231,P=0.631）.The difference in the annual infection rate was not significant either（χ2=6.003,P=0.199）.Children in senior class had the highest rate while those in junior class had the lowest rate（χ2=60.097,P=0.000）.Furthermore,the rate in public kindergarten was lower than in private ones（χ2=7.151,P=0.007）.Enterobius vermicularis distributed widely in Ninghai.Conclusions The prevalence of Enterobiasis in preschoolers is general in Ninghai but the infection rate is low due to the effective prevention and control of Enterobius vermicularis.The work on enterobiasis control and prevention still needs to be strengthened.
