摘要： 【摘要】 目的  通过对2006~2014年枞阳县血吸虫病疫情分析，总结防治经验，为今后的防治对策和措施提供依据。 方法  收集枞阳县2006~2014年防治年度报表等相关防治资料，统计分析逐年的人、牛病情以及螺情指标。 结果  2006年病原学阳性率4.20%，其后降至1%以下，2013、2014连续两年未检出血吸虫感染者，2011年以后未发生急性血吸虫病；耕牛血吸虫感染率2006年为9.34%，其后降至0.95%~3.98%，2012年底28个重点村耕牛全部淘汰。2006~2014年累计新发现、回升钉螺面积228.32hm2、17.86hm2（以江、洲滩环境为主）；净消灭钉螺面积123.87hm2，为2005年实有钉螺面积的5.97%；全县有螺环境的平均活螺密度在0.417 3~1.182 1只/0.11m2之间波动，不同环境类型的活螺密度无统计学差异；2006~2011年感染性钉螺面积呈下降趋势，2013、2014连续两年未检获感染性钉螺。 结论  通过实施以传染源控制为主的综合治理，枞阳县血吸虫病疫情得以有效控制，但螺情依然严峻。今后应在持续加强传染源控制的同时，加大螺情控制力度，以巩固防治成果。

Abstract:

【Abstract】 Objective   To analyze the endemic situation and summarize the experience of schistosomiasis control in Zongyang County from 2006 to 2014, in order to provide evidence for planning appropriate prevention and control measures in the future. Methods  The annual statistical reports and other relative databases on schistosomiasis control were collected in Zongyang County from 2006 to 2014, and analyzed in compliance with yearly human and farm cattle infection with shistosomiasis as well as changes of snail status. Results  Positive rate for pathogen was 4.20% in 2006, which was reduced to below 1%. No infections were detected in between 2013 and 2014, and no acute schistosomiasis occurred since 2011. The infection rate for farm cattle was decreased to 0.95%~3.98% from 9.34% in 2006, and the farm cattle were completely out of service in 28 endemic villages by the end of 2012. Totally, the resurgent and rebounding areas of snails(mainly found in the marshland) were 228.32hm2 and 17.86hm2, respectively, between 2006 and 2014. Snail elimination covered a net area of 123.87hm2, which accounted for 5.97% of the area with snail prevalence in 2005. The average density of live snail habitats varied from 0.417 3 to 1.182 1 snail /0.11m2, and the density of live snails remained no statistical difference in different environments. Infected snails tended to decline from 2006 to 2011, and were not detected in 2013 and 2014. Conclusion  Although endemic schistosomiasis in Zongyang County was effectively controlled after comprehensive management of the infectious sources, yet endemic snails still remain tense. Therefore, it is necessary to strengthen management of the snail sources in following tasks in order to consolidate the present efforts.
