目的：分析和县血吸虫病疫情变化趋势，为该县制定今后一个阶段血防策略提供科学依据。方法收集和县2008~2013年血吸虫病防治工作年报数据、监测点数据及面上防治管理信息资料，纵向分析全县6年间血吸虫病流行态势、疫情分布和流行特点。结果全县人群血吸虫平均感染率总体呈下降趋势，2013年人群感染率已降至0.27%，较2008年下降了73.3%，晚血病人数降至27例，较2008年下降了55%，2011年以后全县连续3年未出现当地感染的急性血吸虫病病例；全县耕牛感染率下降明显，2013年下降为0，较2008年下降了100%；全县有螺面积总体呈缓慢上升趋势，2013年底全县钉螺面积为802.68hm2，较2008年上升了9.1%，阳性螺面积逐年下降，2012年以后，全县未查出阳性钉螺；钉螺复现与新发现情况一度出现上升，2011年后呈逐年下降趋势；钉螺和感染性钉螺密度2011年后呈逐年下降趋势，2013年活螺密度降至0.16只/0.11m2，较2008年下降了56.8%；有螺村数、有螺环境数及阳性螺环境数呈逐年下降趋势，尤其是阳性螺环境数下降幅度较大；村级和镇级传播控制达标升类工作有序推进。结论和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。

Objective To analyze the trend of schistosomiasis endemic situation in Hexian County for planning upcoming strategies in this area. Methods The data of schistosomiasis control, including annual re?port, surveillance sites and routine management, in Hexian County were collected from 2008 to 2013, and ver?tically analyzed for the endemicity, distribution and characteristics of schistosomiasis in the past six years. Re?sults Overall, the average infection rate of schistosomiasis in whole population of Hexian County tended to decline. The infection rate of population was decreased from 73.3%in 2008 to 0.27%in 2013, and the num?ber of advanced schistosomiasis cases were 27, a 55%decrease compared to 2008. No local acute infection oc?curred since 2011. The infection rate for cattle was also significantly dropped to zero in 2013, with a 100%de?crease compared to 2008. The areas with snail showed upward trend in general, and was 802.68 hm2 by the end of 2013, with 9.1% increase compared to 2008. However, the areas with infected snails were presented with yearly decrease, and no infected snails occurred after 2012. Although there was resurgence and new recur?rence of snail, yet this situation was well managed. The density of live snails and infected snails was dropped by 56.8%in 2008 from 0.16 snails/0.11m2 . Apart from that, villages and environment with live snails and infected snails were declined in yearly fashion, particularly, the habitats with infected snails were grealy decreased. Con?clusion The prevalence of schistosomiasis in Hexian County has been effectively contained, and the endemic situation remains lowest in history.
