2017—2019 年武汉市血吸虫病重点水域哨鼠监测报告

目的 及时发现武汉市血吸虫病重点水域水体感染性,减少血吸虫病传播风险。 方法 选择血吸虫病易感重点水域长江武汉段、府河-沦河水系、东荆河-通顺河水系和金水河水系,采用哨鼠监测法监测水体血吸虫感染风险。 结果 2017—2019 年共开展哨鼠监测 38 点次,涉及全市 8 个区 21 个行政村。 三年共投放哨鼠 760 只,回收哨鼠 742 只,总回收率为 97. 63%;共解剖哨鼠 742 只,未发现阳性,未检获成虫,哨鼠感染率为 0。 结论 武汉市血吸虫病重点水域的水体感染性较低。

Surveillance report on schistosomiasis in the key water area in Wuhan City from 2017 to 2019 using sentinel mice

Objective To identify the high-risk environments of Schistosoma japonicum infection in the key water body in Wuhan area for reducing the risks of schistosomiasis.Methods The key water areas with most prevalence of Schistosoma japonicum in Yangtze River within the section of Wuhan City were selected,including Fuhe-Lunhe river system,Dongjing River-Tongshun River system and Jinshui River system.Sentinel mice were used to monitor the risks of Schistosoma japonicum infection.Results From 2017 to 2019,a total of 38 surveillance and forecast sites were detected in 21 administrative villages of 8 districts.Of the 760 sentinel mice placed,742 were recovered,with a recovery rate of 97.63%.No positive infection and no adult worms were found in the 742 sentinel mice dissected.The infection rate of sentinel mouse was zero.Conclusion The infectivity of Schistosoma japonicum remains relative lower in the key water body in Wuhan area.
