目的观察鄱阳湖湖沼型流行区以传染源控制为主的血吸虫病综合防治策略试点的长期防治效果。方法选择鄱阳湖血吸虫病重度流行区爱国、新和、光辉3个村为试点,全面实施以机代牛、封洲禁牧等控制传染源为主的综合防治策略,收集2009-2014年人群病情和螺情数据,比较人群血吸虫感染情况、钉螺感染率和水体危险性的变化。结果 2009-2014年,3个试点村均未发现粪检血吸虫阳性者;牛洲草洲活螺平均密度呈下降趋势,六○圩草洲活螺平均密度基本持平略有下降,2个洲滩均未发现感染性钉螺;解剖哨鼠未发现血吸虫成虫。结论实施以控制传染源为主的血吸虫病防治策略可以使血吸虫病疫情在较长时间内保持稳定。
Objective To observe the long-term prevention and cure effect of pilot programs of integrated control and prevention of schistosomiasis in the endemic areas of Poyang Lake marsh. Methods A total of 3 villages, Patriotic, New and Bright, were selected as pilot projects in the severe epidemic area of Poyang Lake, and comprehensively implemented the integrated prevention and control strategies based on the control of infectious diseases such as machine-driven cattle and ban on animal husbandry, and collected the population from 2009 to 2014 And snail data to compare the population of schistosomiasis infection, snail infection rate and changes in water risk. Results From 2009 to 2014, none of the three pilot villages were found to be positive for stool-seized schistosomiasis. The average density of live snails in the grassland of the Catharanthus roseus tended to decrease. Infectious snails were not found, and no adult schistosomiasis was found in the dissected oestrus. Conclusion The implementation of the strategy of controlling schistosomiasis with predominant infection sources can keep the epidemic of schistosomiasis stable over a long period of time.
