2014年云南省鹤庆县血吸虫病监测村疫情分析

Epidemic Analysis on Village Under Schistosomiasis Monitoring in Heqing County,Yunnan Province in 2014

目的了解云南鹤庆县血吸虫病疫情现状。方法采用随机抽样法在鹤庆县达到血吸虫病传播控制(高原峡谷)和阻断(高原平坝)的地区,各抽取2个行政村,在抽样行政村中选择近期疫情最重、易反复的1个自然村,开展血吸虫病疫情监测。结果 4个监测自然村进行病情监测,没有查到血吸虫患者病畜;对监测村野外收集野粪进行孵化,没有发现血吸虫毛蚴;对查到活螺进行解剖,没有发现阳性钉螺。结论鹤庆县今后的血吸虫病防治应突出以控制传染源为主的血吸虫病防治新模式,有效控制主要的传染源,加强流动人畜的监测与管理,加大控制钉螺的力度。

Objective To understand the current status of schistosomiasis in Heqing county, Yunnan province. Methods Random sampling method was used to select two administrative villages in each area that had a- chieved schistosomiasis transmission control（ plateau canyon）and block （plateau flatland）area in Heqing. One natural village that was with the most server epidemic and repeating was selected in each administrative vil- lage. Results There was no positive snail found in above two types of regions. Four natural villages were moni- tored and there was no schistosomiasis found in human or livestock. Moreover, there was no miracidia found when wild stool hatching in the monitored village as well as no positive snail found after the autopsy to living snails.
