安徽省血吸虫病传染源控制策略研究Ⅰ内陆水网地区以传染源控制为主的综合防治措施预防血吸虫病效果

Effect of the comprehensive control measures with emphasis on infection source control for schistosomiasis in inland water network areas

目的评价内陆水网地区以传染源控制为主的血吸虫病综合防治措施的防治效果。方法 2006～2010年,在南陵县奚滩村实施以传染源控制为主的血吸虫病综合防治措施,观察综合防治措施实施前后螺情、人畜病情变化情况,评价综合防治措施的效果。结果 2010年试区人群平均血吸虫感染率、感染性钉螺密度、钉螺感染率、家畜感染率较实施前分别下降94.2%、100%、100%和100%,连续4年未出现急性感染病例。结论在内陆水网型地区实施以传染源控制为主的综合防治策略能有效控制血吸虫病疫情。

Objective To evaluate the effect of the comprehensive schistosomiasis control measures with emphasis on infection source control in inland water network areas.Methods The comprehensive measures were implemented in Xitan village of Nanling County from 2006 to 2010,the changes of snail status and schistosome infection status of residents and domestic animals were observed,and the effect of the comprehensive measures was evaluated.Results Compared 2006 with 2010,the schistosome infection rate of residents reduced by 94.2%,the density of infection snails reduced by 100%,the infection rate of snails reduced by 100%, and the infection rate of domestic animals reduced by 100%,respectively.There were no acute schistosomiasis cases from 2006 to 2010.Conclusion The comprehensive measures with emphasis on infection source control for schistosomiasis can effectively control the transmission of schistosomiasis in inland water network areas.
