摘要
目的了解引江济巢工程途经地区血吸虫病流行状况,为论证该工程是否会导致钉螺扩散和血吸虫病蔓延提供科学依据。方法按照引江济巢工程拟选择的白荡湖、菜子湖和凤凰颈引江线路,分别调查每条线路引江段、途经地区和入湖段血吸虫病历史和当前流行状况。结果 2007年引江段现有钉螺面积13.1～327.7hm2,占总面积的92.5%,人群血清学查病阳性率为1.9%～22.6%,耕牛感染率为3.2%～6.3%;工程渠道途经地区仅菜子湖线路有螺,面积为38.6hm2,占总面积的7.5%,人群血清学查病阳性率为0.3%～5.2%,耕牛感染率为0～4.2%;工程线路入湖段为血吸虫病非流行区。结论 3条线路均经过血吸虫病流行区,钉螺面积及人畜感染率较高的地区主要分布于各线路引江段。结合历史螺情和当前的流行状况,单纯从血吸虫病防治角度出发,白荡湖线路为最佳选择线路。
Objective To investigate the endemic situation of schistosomiasis japonica along the areas where the Water Transfer Project from the Yangtze River to Chaohu Lake will be built,so as to demonstrate whether the project can cause the spread of snails and transmission of schistosomiasis japonica.Methods The historical and current schistosomiasis endemic data about the entrance,midway and exit of the three possible routes of the Water Transfer Project from the Yangtze River to Chaohu Lake were investigated and analyzed,respectively.Results In the entrance sections of the three possible routes,the areas with Oncomelania snails were 13.1-327.7 hm2,accounting for 92.5% of the total area.The human positive rates of antibody examined by IHA were 1.9%-22.6%.The cattle infection rates examined by hatching method were 3.2%-6.3%.In the midway sections,the area with snails was 38.6 hm2 distributing only in the Caizihu route,accounting for 7.5% of the total area.The human positive rates of antibody examined by IHA were 0.3%-5.2%.The cattle infection rates examined by hatching method were 0-4.2%.The exit sections were not schistosomiasis endemic areas.Conclusions All the three possible routes of the water transfer project go through schistosomiasis endemic areas,with the higher endemic situation of schistosomiasis distributing mainly in the entrance sections.Considering the history snail status and the current endemic situation,the Baidanghu route is the optimal one simply according to schistosomiasis control.
