2012年安徽贵池区钉螺调查报告

Report of snail survey in Guichi District,Antaui Province in 2012

目的了解2012年贵池区钉螺及感染性钉螺分布及变化趋势。方法收集全区近3年有螺环境调查数据,并进行分析。结果贵池区现有钉螺面积2 627.15hm^2,无感染性钉螺。湖沼型流行区有螺面积占89.71%,呈片带状分布,其中以湖滩分布为主;内陆环境点多、散,且环境复杂。钉螺分布主要沿长江、秋浦河、升金湖和九华河流域分布,主要植被是杂草,与居民点距离大多较近,无新发现及复现钉螺。结论贵池区钉螺分布环境复杂,呈逐年下降态势,感染性钉螺首次降为0。要加大螺情监测工作力度,重点打击易感环境,结合综合治理,压缩钉螺及易感环境面积,夯实达标工作。

Objective To understand the distribution and the changing tendency of living snails and infected snails in Guichi District in 2012. Methods The data of snail survey in recent 3 years in Guichi District were collected and analyzed. Results In Guichi District, the area with living snails was 2627.15hm2, and no infected snails were found in 2012. The area with living snails in marshland, which showed a zonal distribution, accounted for 89.71% of the total area with snails, and mainly distributed in the lake areas. Many snail areas were dispersedly distributed in inland with complicated environments. The snails were mainly distributed in the endemic villages located along the Yangtze River, Qiupu River, Shengjinhu Lake and Jiuhua River. The main vegetation was the weed. The environments with snail were mostly close to residential sites. No new or recurrence environments with snail were found. Conclusion The environments with snails in Guichi District were complicated, the snail status showed a declining tendency, and the infected snails were first reduced to 0. It was necessary to strengthen snail surveillance and comprehensive snail control measures to reduce snail areas and susceptible areas, so as to consolidate the achievements of schistosomiasis control.
