Abstract excerpt
High pathogenicity avian influenza viruses (HPAIVs) of the H5N1 and H5N2 subtypes were responsible for 84 HPAI outbreaks on poultry premises in Japan during October 2022-April 2023. The number of outbreaks during the winter of 2022-2023 is the largest ever reported in Japan. In this study, we performed phylogenetic analyses using the full genetic sequences of HPAIVs isolated in Japan during 2022-2023 and those...
