【Abstract】 Objective To investigate the situation of the natural infection of Hantaviruses (HV) in rodents and provide the guidance for the control and prevention of hemorrhagic fever with renal syndrome (HFRS) in Haidian district, Beijing. Methods Rodents were captured by night trap, and lung tissue samples were taken out and stored in liquid Nitrogen. HV was detected by indirect immuno?fluorescence assay (IFA). Results There were 225 rodents captured in different habitats of Haidian district,  which belonged to 3 species and 2 Genera. Rattus norvegicus was the dominant species in the habitats investigated. The total natural infection rates of HV in rodents ranged from 4.60% to 20.00%, and the average was 6.22%. Different species had different natural infection rates. The rate of infection among R.norvegicus and Mus musculus was 6.96% and 6.06% respectively, while Apodemus agrarius was not infected. Conclusion The rodents were infected by HV in Haidian district commonly, and its main host was Rattu Genera.
