Abstract:
OBJECTIVETo make an inquiry into method of typing of hemorrhagic fever with renal syndrome (HFRS).
METHODAverage monthly rates were calculated on the basis of data from 1995 to 1999, then cluster analysis was carried out to type out endemic areas.
RESULTSCompared with the results of 36 surveillance spots from 1980 to 1992, twenty-four surveillance spots had the same results (66.7%). Twenty-three surveillance spots had the same results with the original data in 1999 (82.1%).
CONCLUSIONHFRS incidences increased in spring or in summer, but decreased in autumn or in winter. Cluster analysis seemed to be a supplementary method in distinguishing the epidemic types for HFRS.
