夏季HFRS发病增加与宿主动物带病毒率有关，应加强夏季流行前灭鼠防治工作。
The increase of HFRS incidence in summer is related to the rate of HV carrier of animal host. It is necessary to strengthen control and prevention of HFRS before summer epidemic.
鼠带病毒率最高年度为2002年(8.40%)，2005年以后未发现带病毒鼠。
The highest virus-carrying rate appeared in 2002 (8.40%). After 2005, no virus host animals were observed.
结果：洪涝灾期灾区鼠密度、鼠带病毒率、鼠感染率均明显上升，疫区疫源地传染强度增大，局部灾区已存在HFRS暴发的危险因素。
Results:The density, virus carrying rates, infectious rates were increasing obviously in some flooded areas. Dangerous factors of HFRS outbreak was existed.
