Maximum-likelihood phylogenetic tree for the hemagglutinin genes of a highly pathogenic avian influenza A(H5N8) virus isolated from a seal in the Baltic Sea region of Poland (underlined) and reference sequences. Different clades and the subclades of 2.3.4.4 are marked. Accession numbers for reference sequences are provided; numbers beginning with EPI are from the GISAID EpiFLU database (https://www.gisaid.org), others from GenBank. Scale bar indicates nucleotide substitutions per site.
