目的了解尤溪县肾综合征出血热(HFRS)疫区类型,为防治工作提供依据。方法应用笼夜法捕鼠,计算鼠密度及鼠种构成,对鼠肺进行HFRS病毒抗原检测及病毒分离与鉴定。结果 2008年调查显示褐家鼠为优势种,带病毒率也较高,并从褐家鼠中分离出II型病毒;2010年疫情明显下降。结论尤溪县存在以褐家鼠为主要宿主的家鼠型疫源地,采取了一系列防控措施后,疫情明显下降,说明措施有效。
Objective To understand the types of epidemic area of hemorrhagic fever with renal syndrome (HFRS) in Youxi County, and to provide basis for prevention and treatment. Methods Cage night method was used to catch mice, calculate the density of mice and the structure of mice. The lungs were tested for HFRS virus antigen and the virus was isolated and identified. Results In 2008, Rattus norvegicus was the predominant species with high viral load, and type II virus was isolated from Rattus norvegicus. In 2010, the outbreak was significantly reduced.
