Abstract: Objective To know the composition, distribution and HV-carried condition of host animals in national monitoring site of Hebei province. Methods In four national monitoring sites, investigate the host animals in spring and autumn respectively and population density of rat by trap-night method, and detect the condition of HV-carried by indirect immunofluorescennce assay(IFA). Results At monitoring sites, the population density of rat in residential area ranged from 0.50% to 3.19%, and that in the field fluctuated from 0.13% to 0.94% from 2005 to 2007. The density of rat in residential area was higher than that in the field (χ²=45.022,P<0.01). Rattus norvegicus was the dominant host (77.57%), and then Tscherskia triton (13.63%) and Mus musculus (8.81%). In residential area, there were 6 positive HV antigen and HV-carried rate was 1.91%. There were 2 positive HV antigen in the field, and its rate was 1.23%. Of 8 positive rat, there were 7 R.norvegicus and 1 T.triton. Conclusion Hebei province was a mixed epidemic focus and Rattus was the main host animal. We should took an integrated control measure to destroy the Rattus in residential area. Meanwhile, strengthen further the monitoring of epidemic focus in northern area, and control efficiently the occurrence and prevalence of hemorrhagic fever with renal syndrome(HFRS) in Hebei province.
