Abstract: Objective By analysing the characteristics of transmitting hemorrhagic fever with renal syndrome(HFRS) of Rattus in Changchun district to provide scientific basis for controlling HFRS in Changchun. Methods Rat density was investigated by trap-night method and indirect immunofluorescence technique was used to detect the pulmonary viral antigen of the rat. Results The community of the rats in Changchun was composed of 8 species,Rattus norvegicus,Apodemus speciosus,Mus musculus,Apodemus agrarius,Cricetulus triton,Microtus fortis,Microtus fortis and Cricetulus babrabensis. The average density of the rodents was 7.0%,R.norvegicus was the dominant species,and it's virus carrying rates were the highest in Changchun district. Conclusion R.norvegicus was the dominant species and was the main autoeciousness animals of HFRS,which should be controlled both in the urban areas and in the countryside environment.
