*The virus isolate came from a dead chicken in the backyard of a patient with confirmed infection in Chongqing, China. The host, subtype, and similarity of reference sequences were obtained from the National Center for Biotechnology Information (https://www.ncbi.nlm.nih.gov). HA, hemagglutinin; NA, neuraminidase; NS, nonstructural; M, matrix. PA, polymerase acidic; PB, polymerase basic.
