摘要
目的 评价生态环境变化对血吸虫病疫情的作用。方法 统一调查方案并连续观察 6年 ,监测病情、螺情变化。结果 6年来 ,7种环改方法对降低疫情均有作用。人群患病率、急感发病率、钉螺面积、易感地带面积、钉螺密度、感染性钉螺密度分别降低 86 .7%、10 0 %、70 .1%、92 .0 %、96 .5 %和 10 0 %。结论 改变钉螺孳生的生态环境是阻断血吸虫病传播的一种长效的环保型灭螺措施。
ObjectiveTo evaluate the imp ac t on schistosomiasis endemic through the changes of ecological environment in Hu bei Province. MethodsThe snail conditions and the population prevalance rate of schistosomiasis was supervised for six years a ccording to investigation scheme of the project. ResultsThe prevalance rate of schistosomiasis in residents, the rate of acute infection, snail areas, high risk areas, snail density and infected snail densi ty reduced by 86 7%, 100%, 70 1%, 92 0%, 96 5%, and 100% respectively after the en vironmental modification project was carried out for six years. C onclusionEcologically environmental modification of snail habi tat areas is one of long environmental protection measures for interrupting schi stosomiasis transmission.
