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2010年疫情资料;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 2010年全省累计发病66例,死亡2例,发病率为0.080 6/10万。主要发病地区为南充市、凉山州、成都市。各监测点共捕获鼠10种397只,总鼠密度6.94%,居民区以褐家鼠和小家鼠为优势鼠种,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。结论监测结果未发现可能引起发病率上升或引起流行的相关因素,提示四川省今后2～3年本病可能仍将在低发状态波动,但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 the province in 2010 were collected. At the monitoring point, the rats 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 2010, the cumulative incidence of 66 cases in the province, 2 patients died, the incidence was 0.080 6/10 million. The main areas for the incidence of Nanchong City, Liangshan Prefecture, Chengdu. A total of 397 species of 10 species were captured at all monitoring sites with a total rodent density of 6.94%. Rattus norvegicus and Mus musculus were the dominant species in the residential area, and the dominant species were Brachychilus and Apodemus in the wild. Hantaan virus rate in mice was 0. Conclusion The monitoring results did not find any factors that may cause the rising incidence or epidemic. It suggests that the disease may still fluctuate in the low state in the next 2 ~ 3 years in Sichuan Province, but monitoring work should continue to be strengthened.
