Comparing with Previous data, especially those of 1980s,the morbidity declined from the highest level in the history(49.68/100000)to 2.72/100000 in 1992,which was the relatively low level since 1960s.The epidemic situation in old epidemic areas was controlled, however,new epidemic areas appeared from time to time. In view of the trend of the changes of the seasonal distribution, the rat. density, the virus-carrying rate and the inapparent infection rate of healthy population, the type of epidemic areas of HFRS in this province is a mixed type.
