Phylogenetic tree of hemagglutinin gene sequences from highly pathogenic avian influenza A(H5N1) virus in cat and rats during outbreak in backyard poultry, United States, 2025. The cat, rat, and chicken from this study (pink squares) are closely related to other avian strains, as well as an isolate from a bobcat (GenBank accession no. PV267488). GenBank accession numbers are provided. Scale bar indicates nucleotide substitutions per site.
