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。

Methods The data onschistosomiasis were collected based on the annual reports, information generated from individual monitoringsite and objective data across the county from 2009 to 2014, and analyzed in longitudinally fashion.

The average rate in population was 0.27% in 2014, with an decrease by55.7% compared to 2009. No acute schistosomiasis case and no infected cattle were reported since 2008 and2012, respectively.

The density for living snailswaved between 2009 and 2011, and the density was descended after 2011. In 2014, the density for living snailswas declined to 0.14 pcs/0.1 m2, with a decrease by 65.0% compared to 2009.
