[Serotyping of hemorrhagic fever with renal syndrome in Hubei province].
Ninety-two serum specimens, positive for antibodies against hemorrhagic fever with renal syndrome (HFRS) virus in initial screening with immunofluorescence assay technic (IFAT), were serotyped with micro cell pathogenic effects neutralization test based on preliminary epidemiological classification of epidemic foci of HFRS throughout the province to find out serological evidence of HFRS typing in Hubei Province. It was found that 48 of the specimens were belonged to Type I (HTN) accounting for 52.18 percent, 29 Type II (SEO) for 31.52 percent, and 15 undefined for 16.30 percent. Hubei Province was classified serologically as a mixed prevalent area with Type I as its major component, but all serotypes in different sub-areas have their own features and those in the old epidemic foci were more complex. It indicated that it was better to use a bivalent HFRS virus vaccine, or a single-valent vaccine consistent with local serotype. Serotyping of local HFRS conformed basically to that of epidemiological classification. Local HFRS should be serotyped periodically due to continuous changes in types of foci. Attention to reactions of vaccine immunization should be paid during observation of the effectiveness of the vaccine.
