Epidemic situation and control of soil-transmitted nematodiasis in Jiangsu Province

目的分析总结江苏省土源性线虫病20年来的流行趋势和防治措施,评价防治效果,探讨适合当前流行特点的防治策略和措施。方法收集1990-2009年江苏省土源性线虫病监测、控制措施及防治效果等资料,分析不同阶段的流行特点,评价其防治措施及效果。结果江苏省在不同的防治阶段采取了不同的防治方案。20年来,累计服药防治10 691.66万人次,监测查病204.29万人次。2009年土源性线虫感染率为1.31%,比1990年的59.32%下降了97.79%,表明防治成效十分显著。结论江苏省土源性线虫病流行已得到有效控制。为巩固已取得的防治成果,防治策略应以健康教育、改水改厕和改善环境卫生为主,并继续做好监测、重点人群服药工作以及加强对外来人口土源性线虫病的防治。

Objective To analyze the prevalence changes and the control measures of soil-transmitted nematodiases in Jiangsu Province in the recent 20 years and evaluate the control effect,so as to explore the control strategies and measures appropriate to current epidemic characteristics.Methods The data on surveillance,control measures and control effect of soil-transmitted nematodiases in Jiangsu Province from 1990 to 2009 were collected and analyzed.Results Different control programs were taken in different control stages in Jiangsu Province.A total of 106 916.6 thousand person-times accepted chemotherapy and 2 042.9 thousand person-times were surveyed in the last 20 years.The infection rate of soil-transmitted nematodiases was 1.31% in 2009,which decreased by 97.79% comparing with 59.32% in 1990.The results showed that the control effectiveness was significant.Conclusions The epidemic situation of soil-transmitted nematodiases has been controlled effectively in Jiangsu province.In order to consolidate the control achievements,the control strategies should put emphasis on health education,water supply and sanitation and environment sanitation improvement,meanwhile,the surveillance and medication in key population should continue to be strengthened,as well as soil-transmitted control among migrant population.
