Abstract:

Objective To evaluate the effect of a comprehensive control model for soil?transmitted nematodiasis. Methods Danling County was selected as a demonstration county carrying out the comprehensive prevention model centering on health edu? cation, nematode deworming, and drinking water and lavatories changing. On the other side, Hejiang was selected as a control. The effects were evaluated by comparing some indicators such as the infection rates of soil ? transmitted nematodiasis and so on. Re? sults The infection rates of soil?transmitted nematodiasis declined obviously from 2006 to 2009 in the demonstration county. The infection rates of Ascaris lumbricoides, hookworms, Trichiuris trichiura decreased by 91.14%, 81.65% and 65.77%. In the control county, those rates did not have downward tendency. In 2006, those rates in the demonstration county were higher than those in the control, but in 2009 those rates in the demonstration county were lower than those in the control. Conclusions Through the three? year comprehensive prevention, the infection rates of soil?transmitted nematodiasis declined obviously in the demonstration county. The epidemic situation of soil?transmitted nematodiasis could be controlled effectively by the comprehensive prevention model.

摘要：

目的 评价综合防治模式控制土源性线虫病的效果。方法 方法 在四川省选择土源性线虫感染率较高的丹棱县 （示范县） 和合江县 （对照县） 为观察县， 2006-2009年在示范县全面实施以健康教育、 药物驱虫、 改水改厕等为主要内容的综合防治措施； 对照县未组织实施综合防治。通过人群土源性线虫感染率等指标评价综合防治效果。结果 结果 2009年示范县人群土源性线虫感染率较2006年显著降低， 随年份上升感染率呈下降趋势， 其中蛔虫、 钩虫、 鞭虫感染率分别下降了91.14%、 81.65%和65.77%； 对照县人群蛔虫、 钩虫、 鞭虫感染率均不具有下降趋势性。2006年示范县蛔虫、 钩虫、 鞭虫感染率均高于对照县， 2009年均低于对照县。结论 结论 示范县通过3年的综合防治， 土源性线虫感染率显著降低； 综合防治模式可有效控制土源性线虫病流行。
