摘要
目的掌握达到阻断血吸虫病传播后流行因素的动态变化情况,为制订防治策略提供依据。方法采用机环结合查螺法实行普查、轮查、设监测点等方法查螺;用血清学方法对当地遗漏传染源以及外来流动人员、外来的耕牛(菜牛)开展查病。结果在4个县区38个村查到226个有钉螺条块(次),面积50.46万m2,捕获并解剖钉螺57620只,无阳性钉螺。查病74万人,查到输入病人3例,当地无病人。结论嘉兴地区血吸虫病疫情稳定,但存在残存钉螺。今后监测的重点应是对未经环境改造的历史螺区及其延伸环境、来自疫区的流动人员以及医疗单位对疑似病人检测和报告。
Objective To understand the dynamic changes of prevalent factors of schistosomiasis after interruption of its transmission and provide basis for formulating control strategies in Jiaxing City. Methods The snail situation was surveyed through general, round, monitoring - site surveys, etc. and schistosomiasis cases were serologically detected from missed sources of infection, mobile population from outside and cattle. Results 57 620 snails were captured and dissected from 38 villages in 4 counties/cities covering an area of 50.46m2 and no positive snails were discovered. Three imported schistosomiasis cases were detected form 740 000 people surveyed without local infections. Conclusion The situation of schistosomiasis in this city is stable and there is residual snails.
