OBJECTIVE
To make an inquiry into method of typing of hemorrhagic fever with renal syndrome (HFRS).
METHOD
Average monthly rates were calculated on the basis of data from 1995 to 1999, then cluster analysis was carried out to type out endemic areas.
RESULTS
Compared 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%).
CONCLUSION
HFRS 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.
目的
探讨肾综合征出血热（HFRS）的分型方法。
方法
根据1995年至1999年的数据计算月平均发病率，然后进行聚类分析以划分流行区域。
结果
与1980年至1992年36个监测点的结果相比，24个监测点结果相同（66.7%）。23个监测点与1999年原始数据结果相同（82.1%）。
结论
HFRS发病率在春季或夏季升高，而在秋季或冬季降低。聚类分析似乎是区分HFRS流行类型的一种辅助方法。
