Abstract: Objective Objective To understand the infection status and variation tendercy of Enterobius vermicularis infection among children at national monitoring spots of soil?transmitted nematodosis from 2006 to 2010，and master the epidemic regularity，so as to provide the evidence for making control strategy and evaluating the control effect. Methods Methods A total of 22 national monitor? ing spots of soil?transmitted nematodosis were established according to the National Surveillance Program of Soil?Transmitted Ne? matodiasis（Trial），and the children aged 3-12 years were examined through adhesive cellophane anal swabs，then the infec? tion rates of children with different ages，genders，nationalities and education levels were analyzed. In addition，the advantage， disadvantage，opportunity and threat of the monitoring work were analyzed by SWOT analysis. Results Results A total of 17 068 chil? dren were examined in 22 monitoring spots from 2006 to 2010，and 1 363 of them were found being infected with E. vermicu? laris，the average infection rate was 7.99%，and the infection rates of male and female children were 7.39% and 8.70%，respec? tivel；the average infection rates in each year were 10.01%，9.68%，7.41%，6.96% and 6.57%，respectively. From 2006 to 2009，the infection rates of E. vermicularis in children in Fujian Province was the highest，which were 56.15%，53.42%， 37.82% and 49.53%，respectively，but in 2010，the infection rate in Guangdong Province（46.06%）was the highest. The fur? ther analysis demonstrated that the female children， 3-6 age group，Li nationality and children at kindergarten stage had relative? ly high infection rates. The SWOT analysis showed that the advantage of E. vermicularis monitoring in China was its wide cover? age and continuity，and the disadvantage was the relatively small investment from the government，the opportunity was that the national monitoring spot could drive the monitoring work at the provincial，county and other levels，and the threat was that the work was paid less and less attention to in recent years. Conclusion Conclusion Though the infection rate of E. vermicularis in children at national monitoring spots of soil?transmitted nematodosis has been decreased year by year，high?endemic areas still exist，and thus the work on enterobiasis control and prevention still needs to be strengthened.

摘要： 目的 目的 了解2006-2010年我国土源性线虫病国家级监测点儿童蛲虫感染情况及变化趋势， 掌握流行规律， 为制 定蛲虫病防治对策和评价防治效果提供科学依据。方法 方法 根据 《全国土源性线虫病监测方案 （试行）》， 在全国设立了22 个土源性线虫病国家级监测点， 2006-2010年对监测点受检人群中3~12岁儿童用透明胶纸肛拭法检测蛲虫卵， 对不同性 别、 年龄、 民族、 受教育程度儿童感染率进行分析。此外， 采用SWOT法分析蛲虫感染监测的优势、 劣势、 机遇和挑战。结 结 果 果 2006-2010年， 22个监测点共检查儿童17 068名， 检出蛲虫感染者1 363人， 蛲虫平均感染率为7.99%， 其中男、 女童 平均感染率分别为7.39%和8.70%； 逐年平均感染率分别为10.01%、 9.68%、 7.41%、 6.96%和6.57%。2006-2009年均以福 建省感染率最高， 逐年分别为56.15%、 53.42%、 37.82%和49.53%， 而2010年以广东省感染率最高， 为46.06%。对感染情 况进一步分析显示， 女童、 3～6岁组、 黎族、 托幼儿童感染率较高。SWOT分析显示我国蛲虫监测所面临的优势在于监测 点覆盖面广、 监测连续， 劣势为政府投入相对较少； 机遇为可以利用国家级检测点推动省级、 县级等监测工作的开展， 威 胁为受重视程度降低。结论 结论 虽然土源性线虫病国家级监测点儿童蛲虫感染率呈逐年下降趋势， 但高感染地区仍然存 在， 防治工作有待加强。
