Phylogenetic analysis of neuraminidase gene sequences in study of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus infection in domestic dairy cattle and cats, United States, 2024. Colors indicate different subtypes. Red text indicates the virus gene sequences from bovine milk and cats described in this report, confirming those viruses belong to the N1 subtype. The neuraminidase sequences from this report had 99.52%–99.59% nucleotide identities to sequences from viruses isolated from a chicken and wild birds in 2023.
