Abstract:To summarize the monitoring results of hemorrhagic fever with renal syndrom(HFRS) host animals in Jingzhou from 2017 to 2020, and provide a basis for scientific prevention and control of HFRS. HFRS host animal monitoring was carried out in 8 counties (cities, districts) in Jingzhou City. In spring (April-May) and autumn (September-October), rat traps were placed indoors and in the field by night trapping method. The common habitats in Jingzhou City were selected indoor and field. The captured rats were identified, and the lungs of the identified rats were detected and typed by RT-PCR. From 2017 to 2020, the average rodent rate in Jingzhou City was 4.83% (1106/22910), and the rodent Hantavirus carrier rate was 9.83% (58/590). The top 3 areas of rodent rate were Jiangling County (9.61%), Shashi District (6.44%) and Shishou City (4.92%). The carrier rate of rodent Hantavirus in descending order was Shashi District (17.31%, 27/156), Jiangling County (8.51%, 16/188), Jianli County (8.42%, 8/95) and Honghu City (7.29%, 7/96), no hantavirus was detected in rats caught in other areas. The rodent rate in spring and summer was 5.47% (578/10 566), of which the indoor habitat rodent rate was 6.15% (146/2 374), the rodent hantavirus carrying rate was 1.89% (1/53), and the positive rodent was the Mus musculus captured in the kitchen. The habitat rate of rodents was 5.27% (432/8 192), and the rodent hantavirus carrying rate was 11.76% (16/136). The positive rodent were mainly Apodemus agrarius and Rattus norvegicus captured in wheat fields and shrimp rice fields. The rodent rate in autumn and winter was 4.28% (528/12 344), of which the indoor habitat rodent rate was 6.06% (198/3 269), and the rodent hantavirus carrying rate was 0.78% (1/129). The positive rodent was Flavipectus caught in the miscellaneous room. The rodent rate in the wild habitat was 3.64% (330/9 075), and the rodent hantavirus carrying rate was 14.71% (40/272). The positive rodents were mainly Apodemus agrarius and Rattus norvegicus caught in vegetable fields, shrimp fields, shrimp rice fields, and rice fields. The host animals of HFRS in Jingzhou are mainly Apodemus agrarius and Rattus norvegicus captured in the wild, which carry HNTV and SEOV hantaviruses respectively. The rodent rate and rodent hantavirus carrying rate were higher in Jiangling County and Sand City.
