North American-origin influenza A (H10) viruses in Eurasian wild birds (2022–2024): implications for the emergence of human H10N5 virus

During our surveillance of avian influenza viruses (AIVs) in wild birds across China, H10Nx viruses were isolated from diverse migratory flyways between 2022 and 2024. We identified one wild-bird H10N5 strain that shared a common ancestor with the human H10N5 virus in multiple gene segments. Phyloge...

Description
Summary:During our surveillance of avian influenza viruses (AIVs) in wild birds across China, H10Nx viruses were isolated from diverse migratory flyways between 2022 and 2024. We identified one wild-bird H10N5 strain that shared a common ancestor with the human H10N5 virus in multiple gene segments. Phylogenetic and molecular dating revealed the origin and evolution of H10N5, highlighting the need for continued monitoring.
