摘要： 【摘要】 目的  分析2009~2014年安徽省繁昌县血吸虫病疫情变化趋势，为今后一个阶段血防工作策略制定提供科学依据。 方法  收集该县2009~2014年血吸虫病防治工作年报数据、疫情监测点数据及全县面上防治资料，进行纵向分析。 结果  人群血吸虫平均感染率呈逐年下降趋势，2014年人群感染率已降至0.27%，较2009年下降了55.7%，2008年以后全县未出现当地感染的急性血吸虫病例；全县耕牛血吸虫平均感染率总体呈逐年下降趋势，2012年以后未查出阳性。全县有螺面积呈逐年下降趋势，2014年全县钉螺面积下降至103.2hm2，较2009年下降了16.4%；阳性螺面积总体呈逐年下降趋势，2012年以后全县未查出阳性螺面积。活螺密度2009~2011年呈波动状态，2011年以后呈逐年下降趋势，2014年活螺密度降至0.14只/0.1m2，较2009年下降了65.0%；阳性螺密度总体呈逐年下降趋势。 结论  繁昌县血吸虫病流行得到了有效遏制，血吸虫病疫情降到了历史最低水平。

【Abstract】 Objective  To analyze the change trend of schistosomiasis in Fanchang county of Anhui province from 2009 through 2014 for scientific basis to plan following prevention strategies. Methods  The data on schistosomiasis were collected based on the annual reports, information generated from individual monitoring site and objective data across the county from 2009 to 2014, and analyzed in longitudinally fashion. Results  The infection rate of schistosomiasis in population and in farm cattle as well as areas with infected snails tended to decline year by year in general. The average rate in population was 0.27% in 2014, with an decrease by 55.7% compared to 2009. No acute schistosomiasis case and no infected cattle were reported since 2008 and 2012, respectively. The areas with snails were reduced to 103.2 square meters in 2014, with a decrease by 16.4% compared to 2009, and areas with infected snails were free since 2012. The density for living snails waved between 2009 and 2011, and the density was descended after 2011. In 2014, the density for living snails was declined to 0.14 pcs/0.1 m2, with a decrease by 65.0% compared to 2009.
