2007-2009年三峡库区湖北段血吸虫病监测

Surveillance of schistosomiasis in Hubei section of the Three Gorge Reservoir areas,2007-2009

采用流行病学方法,监测三峡库区血吸虫病传染源及钉螺孳生情况。结果表明,监测点内未发现本地居民感染血吸虫,但有4例输入性慢性血吸虫病人;未发现钉螺孳生及输入。提示应针对可能引起三峡库区血吸虫病传播的危险因素,加强监测并采取相应的干预措施,有效预防和降低血吸虫病在库区流行的风险。

The source of infection of schistosomiasis and snail situation in Hubei section of the Three Gorge Reservoir areas from 2007 to 2009 were investigated by combined epidemiological, immunological and field survey. The results showed that there were no local residents and livestock infected with shchistosome, and no Oncomelania snails were found, but 4 cases of imported patients with chronic schistosomiasis were checked out. It is suggested that the surveillance and intervention should be strengthened pointing to the risk of schistosomiasis transmission in the Three Gorge Reservoir areas, so as to prevent schistosomiasis being endemic in these areas.
