Viral metagenomics in wild ducks reveals the presence of seadornaviruses in Siberia

Seadornavirus is a genus of mosquito-borne viruses that includes Banna virus, which was first discovered in human patients with encephalitis and fever, as well as Kadipiro virus and Liao ning virus. In this study, we used metagenomics to investigate the diversity of viruses in wild ducks and detected both Banna virus and Kadipiro virus in wild birds in Siberia. These data suggest that seadornaviruses, which were previously only found in South East Asia, are also circulating in Northern Eurasia. © 2025.
