【摘要】：目的了解鄱阳湖北岸都昌县钉螺消长趋势,为制定血吸虫病防治策略提供依据。方法收集2005-2012年都昌县的螺情资料,分析其变化趋势。结果 2005-2012年,都昌县活螺平均密度、活螺框出现率、感染螺密度和感染螺面积均呈大幅下降态势,并维持在较低水平,与2005年相比,2008年上述指标分别下降了70.06%、90.33%、79.48%和37.88%,2012年则分别下降了99.35%、98.98%、99.33%和93.93%。钉螺感染率在0.06%~0.53%间波动,呈先降后升态势。自2007年起,各年有螺面积保持在2 052.5 hm2不变。结论至2012年都昌县多数螺情指标均降至历史最低值,但有螺面积未见减少,钉螺感染率呈波动态势,提示血吸虫病传播风险仍然存在,仍需加强钉螺控制。
[Abstract]:Objective to understand the trend of Oncomelania hupensis in Duchang County on the north bank of Poyang Lake, and to provide evidence for the prevention and control of schistosomiasis.Methods the data of snail in Duchang County from 2005 to 2012 were collected and its changing trend was analyzed.Results from 2005 to 2012, the average density of living snail, the occurrence rate of living snail frame, the density of infected snail and the area of infected snail in Duchang County were all decreased significantly, and maintained at a lower level.Compared with 2005, the above indexes decreased by 70.06% and 37.88% respectively in 2008, and 99.355,98.98% and 93.93%, respectively, in 2012.The infection rate of Oncomelania hupensis fluctuated between 0. 06% and 0. 53%.Since 2007, the area of snail has remained unchanged at 2 052.5 hm2.Conclusion by 2012, most of the snail status indexes in Duchang County have been reduced to the lowest value in history, but the snail area has not been reduced, and the snail infection rate is fluctuating, indicating that the transmission risk of schistosomiasis still exists and the control of snail still needs to be strengthened.
