Abstract: Objective To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome(HFRS) in Hebei province in 2005,to analy the data by surveillance and to provide scientific evidence for its control and prevention. Methods The pestilence situation data of HFRS was collected. Host animals of monitoring site were monitored. The recessive infection rate of the crowd was investigated. The genotype of positive lungs of the mice was identified. Results The 1741 cases of HFRS and 7 deathes had been reported in Hebei province in 2005. The morbidity was 2.54/100 000 and the mortality was 0.40. All the cases were distributed in 139 counties (cities,districts) and the main attacked areas were Qinhuangdao city and Tangshan city. Dominant peak was found in spring. Besides,the 57.96 of all the cases occurred from March to June. Young people were the major crowd of the disease,1351 cases were among the age of 20-59,amounting to 77.60,and the ratio of male vs female was 2.77∶1.Peasants amounted for 69.50.The rat density in populated area was 1.48,the hantavirus-carrying rate was 4.62; and which in the open country was 0.99,the hantavirus-carrying rate was 0.97.The predominant species of rats were Rattus norvegicus. The recessive infection rate of the crowd was 5.36.The typing of positive lungs by PCR showed that belonged to rattus type (type Ⅱ). Conclusion Hebei province is a mixed epidemic area and rattus type (type Ⅱ) is the major type. We should place emphasis on the eight counties (districts) with more cases,carry out complex prevention and control strategy scientifically for HFRS.
