Abstract: Objective To evaluate the effect of schistosomiasis control strategy with emphasis on infection source control in the Yongxiu County promotion zone of Poyang Lake region. Methods The Wucheng Township of Yongxiu County was selected as the observation site， and the effect of the comprehensive control strategy was evaluated by using the method of field surveys combined with retrospective investigations. Results In 2010， there were 17 persons whose stool tests for schistosome infection were positive， and the number of calculated schistosomiasis patients was 2 331. The infection rate of cattle was 4.5%， and the area with infected Oncomelania hupensis snails was 10.00 hm2. In 2011， the comprehensive control strategy was carried out， and in 2012， there were no cattle in the promotion zone. In 2013 and 2014， there were no schistosomiasis patients with positive stool tests. In 2014， no schistosome infected snails were found.

摘要： 目的 评估鄱阳湖区血吸虫病传染源控制策略在永修县推广区的实施效果。方法 选择永修县吴城镇为推广区观察点，采用现场调查和回顾性调查相结合的方法，评估该区实施血吸虫病传染源控制策略后的防治效果。结果 2010年吴城镇有粪检血吸虫阳性病人17人、推算病人数2 331人，耕牛血吸虫感染率4.5%，感染性钉螺面积10.00 hm2。2011年推广区实施传染源控制策略，2012年起淘汰了全部耕牛和羊，2013年和2014年未再查到粪检阳性病人，2014年未再查见血吸虫感染性钉螺。结论 永修县推广实施血吸虫病传染源控制策略后，有效地控制了血吸虫病的流行传播，取得了显著的防治效果。
