为探讨肾综合征出血热 (HFRS)流行规律与疫源地类型 ,以制定有针对性的防制措施。采用直接免疫荧光法 (FAT)检测鼠肺汉坦病毒 (HV)抗原 ;采用间接免疫荧光法 (IFAT)检测EHF病人血清中抗体 ,血凝抑制试验 (HI)进行血清学分型。结果表明 ,全省 2 2 30例病人 ,主要分布在浙东和浙西丘陵区 ,1月和 5、6、7月为二个发病高峰 ,青壮年农民发病最多。对以姬鼠型为主的混合型疫区 ,应选择双价疫苗进行预防接种 ,以控制疫情。
In order to explore the epidemic of HFRS and the types of foci in the area of hemorrhagic fever with renal syndrome (HFRS), aiming to make targeted prevention and control measures. Hantavirus (HV) antigen was detected by direct immunofluorescence (FAT); Serum antibody and hemagglutination inhibition (HI) were detected by indirect immunofluorescence assay (IFAT) for serotyping. The results showed that 2,230 patients in the province were mainly distributed in the hilly areas of eastern Zhejiang and western Zhejiang, with the peak incidence in January and May, June and July, and the highest incidence among young and middle-aged peasants. To the agar-based mixed-type epidemic area, should choose bivalent vaccine for vaccination, in order to control the outbreak.
