2004-2013年公安县血吸虫病监测点疫情分析

Schistosomiasis endemic situation at a national surveillance site in Gong'an County,Hubei Province from 2004 to 2013

目的分析了解公安县血吸虫病国家监测点血吸虫病疫情状况。方法按照《全国血吸虫病监测方案》的要求,每年在张家湖村监测点开展螺情和人畜病情的调查与检测,计算疫情指标并进行统计分析。结果 2004-2013年张家湖村人群血吸虫感染率分别为10.66%、7.86%、4.29%、2.48%、1.09%、1.09%、0.91%、0.56%、0.75%、0.58%,耕牛感染率分别为12.75%、10.22%、9.24%、3.88%、0、2.72%、1.98%、1.86%、0.78%、0,总体均呈下降趋势;与2004年相比,2013年人群感染率下降了94.75%,且完全消除了散放耕牛现象。2004年监测点有螺面积19.3 hm2,2007年以来降至并维持在6.3hm2,有螺面积减少了67.36%,2004年查出感染性钉螺面积0.1 hm2,自2005年起未查到感染性钉螺;2004年活螺平均密度0.99只/0.1 hm2,2013年为0.07只/0.1 hm2,下降了92.93%。结论张家湖村近10年来血吸虫病疫情大幅下降,取得了较好的防治效果。

Objective To understand the schistosomiasis endemic situation at a national surveillance site in Gong＇an County,Hubei Province. Methods According to The Scheme of Schistosomiasis Surveillance in China,the schistosome infectionrates of residents and cattle,and the Oncomelania hupensis snail status were investigated yearly in Zhangjiahu Village,a national surveillance site,in Gong＇an County from 2004 to 2013. Results From 2004 to 2013,the human schistosome infectionrates decreased from 10.66% to 0.58%,and the cattle schistosome infection rates from 12.75% to 0. Meanwhile,the snail areasand densities reduced,and the schistosome infected snails were eliminated. Conclusion The schistosomiasis endemic situation declined dramatically at the surveillance site,and schistosomiasis is well-controlled.
