摘要：

目的评价江陵县3个流行村实施以机代牛为主的综合防治措施控制血吸虫病效果。方法选择江陵县金旗、玉古、花章等3个已实施以机代牛的血吸虫病流行村，比较其以机代牛控制传染源为主的综合防治措施实施前后人、畜和钉螺感染情况，并采用问卷形式对居民满意度进行调查。结果金旗、玉古、花章等3个流行村2009年人群血吸虫感染率分别为1.87%、2.72%、2.89%；2010年实施以机代牛控制传染源为主的综合防治措施后，2011年人群血吸虫感染率分别下降至0.67%、1.91%、1.75%，下降幅度分别为29.78%、64.17%、39.45%；完全淘汰耕牛的金旗村和玉古村2011年未再发现感染性钉螺；花章村2011年仍有耕牛35头，未发现耕牛感染，但感染性钉螺面积为0.52 hm2。3个村群众对以机代牛措施的满意度达89.21%。结论以机代牛控制传染源为主的综合性防治措施控制血吸虫病效果明显，但以机代牛政策后期的落实还有赖于必要的配套措施
