Abstract: Objective By analysing the epidemic characteristics of host animals of hemorrhagic fever with renal syndrome(HFRS) in Hebei province to provide scientific evidence for its prevention and control.Methods Rodents density was investigated by trap-night method and immunofluorescence technique was used to detect the virus antigen.Results At residential area the rodent density was 1.84%,and the hantavirus-carrying rate was 3.33%,the species of rodents include Rattus norvegicus,Mus musculus,Cricetulus triton.R.norvegicus had the highest hantavirus-carrying rate that was 3.35%;In farring area the density was 1.13%,and the hantavirus carrying rate was 2.44%,the community was composed of R.norvegicus,M.musculus,Apodemus agrarius,C.triton,Microtus fortis,Ap.peninsulae,and R.confucianus.Ap.agrarius had the highest hantavirus-carrying rate that was 6.67% among these rodents.R.norvegicus distributied in different communities of rodents in different districts,and it was the dominant species.The next ones were the M.musculus and C.triton,distributed in 9 cities,constituent ratio was at the second position.The others,including,Ap.agrarius and M.fortis,distributed in few districts.R.confucianus and Ap.peninsulae were captured only in the mountain area of Chengde located in the north of Hebei province.Conclusion R.norvegicus was the main host animals of hantavirus in Hebei province,which take an important role in transmitting of HFRS.Therefore,we should take composite control measures to the community of rodent,to control the epidemic of HFRS.
