摘要： 目的 了解南水北调东线工程高邮段血吸虫病疫情现状。 方法 采用系统抽样结合环境抽样法对南水北调东线工程高邮段大运河、三阳河及毗邻的湖区进行钉螺监测调查;采用网捞法和稻草帘诱螺法对大运河和三阳河监测点进行水体钉螺监测;采用 DDIA 和 IHA 对相关监测区居民及家畜进行血吸虫病筛查,筛查阳性者采用粪便孵化法或 Kato-Katz 法进行病原学检测。 结果 2016-2019 年大运河和三阳河河道累计调查钉螺面积 309. 66 hm2,未发现钉螺;毗邻的湖区累计调查面积 11 402. 74 hm2,查出有螺面积 27. 55 ~ 77. 51 hm2。 监测点打捞漂浮物 125 kg,投放稻草帘 160 块,均未发现钉螺。 人群查病 31 311 人次,其中 DDIA 阳性 226 人次;病原学查病 10 736 人次,未发现阳性。 家畜调查 1 083 头次,未发现病畜。 结论 南水北调东线工程高邮段未发现血吸虫病疫情和钉螺扩散,但开展血吸虫病和钉螺监测仍然十分必要。

Abstract: Objective To understand the epidemic of schistosomiasis in Gaoyou sections of Eastern Route of the South-to-North Water Diversion Project. Methods  The Oncomelania snails were monitored by means of systematic sampling combined with environmental sampling in the Grand Canal, Sanyang River and the adjacent lake areas. Net salvage and rice straw curtains were used to capture the snails for survey of their prevalence in the surveillance sites of the Grand Canal, Sanyang River. Dipstick dye immunoassay( DDIA) and indirect hemagglutination ( IHA) were used to screen residents and livestock in the monitoring area. Both population and livestock with positive findings further underwent pathogen detection using stool hatching or Kato-Katz technique. Results The Oncomelania snails were not found in the Grand Canal and Sanyang River from 2016 to 2019. Investigation of a total area of 11 402. 74 hm2 in the adjacent lake area revealed that areas with snails were between 27. 55 hm2 and 77. 51 hm2. Totally, 125 kg floating debris was refloated and 160 pieces of rice straw curtains were placed in the surveillance sites, in which no snails were detected. Of the 31 311 residents (person-time) underwent detection, positive for DDIA was found in 226, yet infection was free in the 10 736 residents( person-time) received pathogen detection. No infection was seen in the 1 083 livestock detected. Conclusion Although there is no spreading of the Oncomelania hupensis and schistosomiasis prevalence in Gaoyou sections of Eastern Route of the South-to-North Water Diversion Project, yet surveillance over the snails and schistosomiasis remains necessary in those areas.
