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 controlling schistosomiasis by comprehensive prevention and control measures based on infection source control in the endemic areas of schistosomiasis Island. Methods In the relatively isolated island-type schistosomiasis endemic area, Tongling County, Laozhou Township, we implemented full control measures such as “substituting machinery on behalf of cows”, “changing water to flush toilets” and “livestock raising” And supplemented by check and cure disease, snail check, health education and other conventional control measures, comprehensive prevention and control measures after the implementation of the township snail and resident schistosome infection were observed. Results No acute schistosomiasis infection occurred within 2 years after the implementation of comprehensive control measures based on infection source control. After 2 years, the infection rate of schistosomiasis dropped to below 0.5%; the number of positive spirochetes decreased by 75% and the positive spiral density was reduced to 0.0005 /0.1m2, down 96.67%. Conclusion The comprehensive prevention and control measures based on infection source control can effectively control the epidemic of schistosomiasis.
