摘要： 目的  了解安徽省怀宁县血吸虫病疫情变化情况，为制订血吸虫病防治策略提供参考依据。 方法  收集2009～2012年怀宁县血吸虫病疫情监测报表、年报表及有关螺情、病情资料，分析血吸虫病流行状况和特点。 结果 2009～2012年，该县省级血吸虫病监测点人群感染率显著下降，2012年全县三类村和四、五类村血吸虫病血检阳性率较2009年分别下降了45.54%和51.41%，2012年现存晚期血吸虫病人为313例，4年间未发现急性感染病人。2009～2012年全县耕牛感染率分别为1.5%、1.48%、0.88%和0.71%，呈逐年下降趋势；4年中全县有螺面积降幅不明显，但感染性钉螺面积和密度明显下降；2012年未查获感染性钉螺。 结论  大力推进以传染源控制为主的综合性防治策略是有效控制血吸虫病疫情的治本之策。

There were 313 advanced schistosomiasis cases in 2012, and no acute cases were found from 2009 to 2012. The infection rate of cattle in the 4 years was 1.5%, 1.48%, 0.88% and 0.71%, respectively, and there was an obviously decreasing tendency. There was no significant decrease on snail areas from 2009 to 2012, while the areas with infected snails and the mean density of infected snails both decreased obviously, and no infected snails were found in 2012.  Conclusion  It was suggested that promoting the comprehensive control strategy with emphasis on infectious source control was an effective measure to control schistosomiasis
