目的分析三峡库区湖北段血吸虫病监测结果,并提出相应防治对策。方法采用流行病学、免疫学和现场调查相结合的方法,调查三峡库区传染源及钉螺情况。间接血凝试验(IHA)筛查库区居民440人(其中外出打工返乡人员36人)及流动人口45人;在监测点调查耕牛并对全部耕牛进行间接血凝检测;在库区长江支流、两岸洲滩、沟渠等适合钉螺孳生的危险环境进行查螺;调查钉螺输入情况。结果监测点未发现血吸虫病病人和病牛;未发现钉螺孳生及输入。结论针对可能引起三峡库区血吸虫病传播的危险,应加强监测和采取相应的干预措施,防止血吸虫病在库区发生和流行。
Objective To analyze the monitoring results of schistosomiasis in Hubei in the Three Gorges Reservoir Area and to propose corresponding control measures. Methods The methods of epidemiology, immunology and field investigation were used to investigate the source of infection and snail in the Three Gorges reservoir area. Indirect hemagglutination test (IHA) Screening 440 residents (including migrant workers return home 36) and the floating population of 45; survey of cattle at the monitoring point and all cattle indirect hemagglutination test; in the reservoir area The tributaries of the Yangtze River, beaches and ditches across the Taiwan Strait, which are suitable for snail breeding. Results No schistosomiasis patients and diseased cattle were found at monitoring sites; snail breeding and input were not found. Conclusion In view of the risk of schistosomiasis transmission in the Three Gorges Reservoir area, we should strengthen the monitoring and take corresponding intervention measures to prevent the occurrence and prevalence of schistosomiasis in the reservoir area.
