摘要
目的了解泾县钉螺分布变化趋势，对制订相同类型流行区今后一段时期血吸虫病防治策略具有重要意义。方法收集2000～2009年泾县钉螺分布面积、易感环境钉螺面积及复现和新发现钉螺面积等资料，观察其变化趋势，并分析影响其变化的相关因素。结果2000年以来，受洪涝灾害和青弋江灌区总干渠水位等因素影响．泾县钉螺面积呈上升趋势：新发现钉螺面积出现4个高峰期．分别是2000年、2002年、2004年和2008年，复现钉螺面积出现2000年、2002年和2008年3个高峰期：易感环境面积出现2004年、2009年2个高峰期。结论泾县钉螺分布状况受自然和社会等多方面因素影响，短期内消灭钉螺的目标难以实现．采取传染源控制结合小区域综合治理等措施压缩易感环境钉螺面积．减少人畜感染为现阶段最适宜的防治策略。
Objectiv To understand the trend of snail distribution and make out control strategies in hilly endemic regions. Methods The data of snail distribution from 2000 to 2009 was collected, including the area of snail distribution, newly current and recurrent and the density of snail and infected snail, etc. The influence factors were analyzed. Results Affected by the flooding and water level fluctuations of irrigation canal of Qingyi river, the snail area showed a trend of inclining after 2000. 4 peaks appeared for the area of snail newly appeared in 2000, 2002, 2004 and 2008, respectively. 3 peaks appeared for the areas of snail reappeared in 2000, 2002 and 2008, respectively. 2 peaks appeared in 2004 and 2009 for the areas with high transmission potential. Conclusion The distribution of snails in Jing County was related to natural, social and financial circumstance, and it was hard to control snail in a short time. Therefore, it was reasonable control strategies to reduce the infection of people by taking infection source control and comprehensive measures to reduce snail areas in high transmission regions at present.
