Article Synopsis
- The study aimed to identify hosts of hantavirus (HV) and understand its molecular epidemiology to aid in preventing hemorrhagic fever with renal syndrome (HFRS).
- Researchers captured 1,421 rodents in Chuxiong prefecture, finding that 5.15% tested positive for HV, predominantly belonging to Rattus norvegicus and Rattus flavipectus.
- The sequencing of positive specimens revealed that they were primarily Seoul type hantavirus, with significant genetic similarities to existing strains, indicating its widespread presence and potential risk in the local environment.
