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2052.5 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。

Objective To understand the dynamic of Oncomelania hupensis snail status in Duchang County at north shore of Poyang Lake so as to provide the evidence for formulating the strategy of schistosomiasis control. Methods The data about the snail status in Duchang County from 2005 to 2012 were collected and the change trend of the snail status was analyzed. Re?sults From 2005 to 2012 all the average density of living snails the occurrence rate of frames with living snails the density of infected snails and the area with infected snails showed a trend of sharp decline and stayed at a low level. Compared to 2005 the above 4 indexes in 2008 decreased by 70.06% 90.33% 79.48% and 37.88% respectively and those in 2012 decreased by 99.35% 98.98% 99.33% and 93.84% respectively. The infection rates of snails fluctuated between 0.06%and 0.53%which showed a trend of first decrease and then increase. The snail area maintained at the level of 2 052.5 hm2 since 2007. Con?clusions Most of the indexes of the snail status in Duchang County have decreased to the lowest level in history since 2012 but the snail area is stable and the infection rate of snails shows a fluctuation trend which suggests that the risks of schistosomia?sis transmission still exist and the snail control still should be strengthened.
