摘　　要：目的评价在洲岛型血吸虫病流行区实施以传染源控制为主的综合防治措施控制血吸虫病的效果。方法在环境相对孤立的洲岛型血吸虫病流行区铜陵县老洲乡全面实施"以机代牛"、"改水改厕"、"家畜圈养"等传染源控制措施,并辅以查治病、查灭螺、健康教育等常规防治措施,综合防治措施实施后连续对全乡螺情及居民血吸虫感染情况进行观察。结果以传染源控制为主的综合防治措施实施后2年未发生急性血吸虫感染,2年后居民血吸虫感染率降至0.5%以下;阳性螺环境数减少了75%,阳性螺密度降为0.0005只/0.1m2,下降了96.67%。结论以传染源控制为主的综合防治措施可有效控制血吸虫病流行。Objective To evaluate the effect of the comprehensive measures with emphasis on infectious source control for schistosomiasis control in islet endemic regions. Methods Laozhou Township of Tongling County,an isolated islet endemic region,was selected as a pilot area to carry out the comprehensive measures. The snail status and the infection of the residents were surveyed after carrying out the comprehensive measures. Results There were no acute schistosomiasis cases occurred in the next two years after carrying out the comprehensive measures. The infection rate of residents reduced to below 0.5%,the number of spots with infected snails decreased by 75%,the density of infected snails decreased by 96.67% with 0.000 5 snails/0.1 m^2 in the second year. Conclusion It could control schistosomiasis transmission effectively to carry out the comprehensive measures with emphasis on infectious source control for schistosomiasis control.
