摘要： 目的  描述并分析临澧县血吸虫病疫情出现两次回升前后螺情与病情的动态变化，找出变化规律，为血吸虫病防治工作提供科学依据。 方法  采取回顾性调查方法，搜集、记录临澧县从1960年到2013年的血吸虫病疫情资料，建立调查资料数据库，分析螺情、病情变化趋势及规律。 结果  临澧县两次血吸虫病疫情回升过程中，均有螺情回升，且钉螺密度与人群，牛感染率均呈正相关（1982~1997年：r人=0.879，P<0.01：r牛=0.898，P<0.01。2003~2013年：r人=0.791，P<0.01；r牛=0.845，P<0.01）。 结论  螺情是血吸虫病疫情回升的重要预警指标，有效控制螺情是减少血吸虫传播的重要手段。血吸虫病防治工作为一项长期性的工作，当血吸虫病疫情降低到一定水平时，应加强疫情监测预警，防止疫情反弹。

Abstract:

Objective  To analyze the dynamic changes of schistosomiasis infection and Oncomelania snails before and after the twice rebounds in history of schistosomiasis endemic in Liling county, in order to find the prevalence rules for scientific evidence in following prevention and control of schistosomiasis. Methods  Retrospective investigation was conducted through collection and review of the schistosomiasis endemic data in Liling county from 1960 to 2013. Then the database was established for analysis of the trends and rules of changes of snail status and infections in humans and cattle. Results  Twice rebounds of schistosomiasis endemic in history in Linli county were associated with rebounded snail prevalence, and positively correlated with snail density, infection rate in population and cattle(1982~1997: rhuman=0.879, P<0.01; rcattle=0.898, P<0.01; 2003-2013: rhunan=0.791, P<0.01; rcattle=0.845, P<0.01). Conclusion  Snail prevalence status can be critical indicators for estimation of epidemic situation, and effective control of snails may reduce the schistosomiasis transmission. Nevertheless, prevention and control of schistosomiasis should be long-term efforts, and monitoring and warning systems should be strengthened to prevent the endemic schistosomiasis from rebounding even the endemic remains in lower level.
