目的了解四川省肾综合征出血热(HFRS)疫情及宿主动物动态,为HFRS的防制提供科学依据。方法收集全省2011年HFRS疫情资料;在监测点采用夹夜法捕鼠,将鼠肺冷冻切片,用免疫荧光法检测汉坦病毒抗原。结果 2011年全省HFRS累计发病60例,死亡2例;主要发病地区为达州市、凉山州、南充市。各监测点共捕获鼠10种63 1只,总鼠密度8.94%,居民区以小家鼠和褐家鼠为优势鼠种,野外以四川短尾鼩和高山姬鼠为优势鼠种。鼠间汉坦病毒带病毒率为0.27%。结论 2011年四川省监测结果未发现可能引起HFRS发病率上升或引起流行的相关因素,今后应继续加强监测工作。
Objective To understand the epidemic situation and host animal dynamics of hemorrhagic fever with renal syndrome (HFRS) in Sichuan Province and provide a scientific basis for the prevention and control of HFRS. Methods The epidemic data of HFRS collected in 2011 in the province were collected. In the monitoring spot, the mice were caught by the method of catching the night and the rat lungs were frozen and sectioned for the detection of Hantavirus antigen by immunofluorescence. Results In 2011, there were 60 HFRS cases in the province and 2 deaths. The main disease areas were Dazhou, Liangshan and Nanchong. A total of 63 species of 10 species were captured at each monitoring spot, with a total rodent density of 8.94%. The dominant species were Mus musculus and Rattus norvegicus in residential areas. Hantaan virus rate was 0.27%. Conclusion The monitoring results in Sichuan Province in 2011 found no relevant factors that could cause the rising incidence of HFRS or cause epidemics, and the surveillance should continue to be strengthened in the future.
