Surveillance on the HFRS had been carried out during the period of 1986-1993. Rodent density ranged from 4.6%-12.2% with R.norvegicus exceeding 60% in all kinds of rodents. HV antigen carrier rate of R.norvegicus was 1.3%-7.5%, much higher than that among other rodents. A significantly positive correlation had been observed between the HFRS morbidity and the R.norvegicus density. Of 129 specimens from HFRS patients, 89% belonged to the type of SEOV. In the eastern and centre Parts of Hebei plain, HTNV occupied 1.6%. A total number of 9,609 HFRS patients had been identified during the period of 1980-1993. The plain area in Hebei province was recognized as the major epidemic area. The key measure for decreasing the HFRS morbidity was deratizationin in the residential area in January and February and immunization with HFRS inactivated vaccine.
1986 - 1993年期间开展了肾综合征出血热（HFRS）监测。鼠密度为4.6% - 12.2%，其中褐家鼠在各类鼠中占比超过60%。褐家鼠汉坦病毒抗原携带率为1.3% - 7.5%，远高于其他鼠类。观察到HFRS发病率与褐家鼠密度之间存在显著正相关。在129份HFRS患者标本中，89%属于汉城型汉坦病毒（SEOV）。在河北平原东部和中部地区，汉滩病毒（HTNV）占1.6%。1980 - 1993年期间共确诊9609例HFRS患者。河北省平原地区被认定为主要疫区。降低HFRS发病率的关键措施是在1月和2月对居民区进行灭鼠以及接种HFRS灭活疫苗。
