Figure 1

Maximum-likelihood phylogenic analysis of the hemagglutinin gene segment of the first sequenced set of wild bird isolates of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4 virus, United States, 2021. Red indicates US wild bird highly pathogenic detections, and blue indicates closest virus detected in Newfoundland, Canada. MAFFT alignment and RAxML trees were generated in Geneious 11.1.5 (https://www.geneious.com) and visualized in FigTree 1.4.1 (https://tree.bio.ed.ac.uk). Scale bar indicates average nucleotide substitutions per site.
