Objective To analyze the epidemic characteristics of hemorrhagic fever with renal syndrome(HFRS), the distribution and virus-carrying status of host animals in Zibo, China in 2015, so as to provide evidences for establishing prevention and control measures. Methods Descriptive epidemiological analysis was conducted on the incidence data of HFRS, Excel 2007 and SPSS 16.0 software were used to analyze the surveillance data of HFRS host animals. Results A total of 84 cases including one death were reported in the entire city in 2015, a decline of 35.88% compared with that in 2014, and the case fatality rate was 1.19%. The cases were distributed mainly in Yiyuan county and Zichuan district,which accounted for 72.62%. Middle and old-aged male farmers were the main victims in these cases. The age group of 45-69 accounted for 70.24% of the cases. Two peak seasons were observed in spring (March-May) and autumn-winter (October-December). The average rodent density was 5.99%, the virus-carrying rate was 8.80%. Rattus norvegicus was the predominant species of rodents in the residential areas. In the farm land, the predominant species was Apodemus agrarius. All the 11 lung samples isolated from R. norvegicus in autumn were positive as Soul virus. Conclusion The incidence rate of HFRS declined in Zibo city, but the rodent density and the virus-carrying rate were still high in some areas, the risk of HFRS outbreaks in these areas remains. It is necessary to strengthen immunization, rodent control and health education in high-endemic areas.
