【摘要】：目的了解2016年湖北省血吸虫病重点水域的水体感染性,分析可疑高危环境血吸虫病的传播风险。方法选择长江、汉北河、富河3大水系设立哨鼠监测预警点。采用哨鼠法检测水体的感染性,同时观察滩面人畜活动情况,对出现血吸虫尾蚴感染性水体的区域启动应急响应机制。结果 5-6月在10个哨鼠监测点中,长江流域有2个点检出阳性哨鼠,阳性点检出率为20%,回收的200只小鼠全部解剖,检出阳性哨鼠5只,哨鼠总感染率为2.5%,获得血吸虫成虫5条,阳性鼠平均虫荷为1条/鼠。对2个哨鼠阳性点及时启动了应急响应机制,未出现血吸虫病重大疫情。8-9月8个哨鼠点,160只小鼠全部解剖,未查出血吸虫感染阳性哨鼠。结论哨鼠监测结果对分析湖北省血吸虫病传播风险具有重要意义。
[Abstract]:Objective to investigate the water infectivity of schistosomiasis in key waters of Hubei Province in 2016 and to analyze the risk of transmission of schistosomiasis in suspected high-risk environment. Methods the sentinel monitoring and warning points were set up in the Yangtze River, Hanbei River and Fuhe River. The method of sentinel rat was used to detect the infection of water body, and to observe the human and animal activities on the beach surface, and to initiate the emergency response mechanism for the area infected with schistosomiasis cercariae. Results among the 10 sentinel rat surveillance sites in May and June, there were 2 positive sentinel rats in the Yangtze River valley, the positive rate was 20. All the 200 mice were dissected, 5 positive sentinel rats were detected, the total infection rate of sentinel rats was 2.5, and 5 adult Schistosoma japonicum were obtained. The average worm load of positive mice was 1 / mouse. The emergency response mechanism was initiated for 2 sentinel positive sites in time. There was no significant schistosomiasis epidemic. All 160 Sentinel mice from August to September were dissected, and no positive sentinel mice were found to be infected with Schistosoma japonicum. Conclusion the results of sentinel surveillance are important to analyze the risk of schistosomiasis transmission in Hubei Province.
