流行性出血热(EHF)是一种以鼠为主要传染源的自然疫源性疾病。我省自1962年在遵义县发现本病以来,疫区不断扩大,病例增加迅速,是国内重发病区之一。疫情资料及血清学调查表明,我省东部、南部及西部边区28县为EHF非疫区。1985～1987年间,我们用直接兔疫荧光技本(DEA)对该28县进行了EHF调查。材料和方法一.标本采集:在人口密集,交通发达村镇采用鼠夹法捕鼠。获鼠后进行鼠种鉴定,剖取鼠肺送实验室待检。
Epidemic haemorrhagic fever (EHF) is a naturally foci of disease with a mouse as its major source of infection. Since the disease was discovered in Zunyi County in 1962, the province has continuously expanded its epidemic area and the number of cases has increased rapidly. It is one of the most frequently reported wards in China. Epidemic data and serological surveys showed that 28 counties in the eastern, southern and western border areas of our province were designated as EFA non-epidemic areas. Between 1985 and 1987, we conducted an EHF survey of 28 counties using the direct immunofluorescence assay (DEA). Materials and methods A. Specimen collection: in densely populated, traffic developed villages and towns using rat-trap method to catch rats. Rat mice were identified after species, dissected rat lung delivery laboratory pending.
