Abstract: Objective To identify the spatial distribution of rodents and hantavirus infection in Beijing.Methods Nine sites in Beijng were selected for a survey of HV reservoirs,especially the rodents.The captured hosts were identified.RT PCR was used to amplify the partial M fragments of hantavirus to determine the positive rate.The character of spatial distribution of hantavirus infection of rodents population was analyzed using SPSS software.Results 387 rodents were captured,among which Rattus norvegicus was the dominant species.The significant difference of spatial distribution of HV reserviors community and HV prevalence in selected sites had not been observed.The infection of SEO HV was widely distributed in the area studied,and mainly restricted to Rattus norvegicus and Mus musculus.The results of present study show that rodents from non domestic habitat did not carry HV.There was no significant difference of HV prevalence among sites as well as among 9 different niche.Significant difference in infection rate of HV was observed between domestic habitat and field habitat(include cultivation,brushwood and forest).Conclusion There are to a certain extend differences of rodents community and HV infection among different sites and different habitat in Beijing.The SEO HV infection of rodents was widely distributed in domestic habitat in Beijing and the major host of hantaviruse in Beijing was Rattus norvegicus.The new nature focus of HTN HV was not found.
