Maximum likelihood tree constructed using Mega 5.0 under GTR‐GAMMA model of nucleotide evolution, displaying phylogeny of concatenated full‐genome WCP A(H5N8) virus sequences (n = 13) in reference to publically available A(H5N8) sequences representative of the global A(H5N8) diversity between 2016 and 2017. Branch with the WCP is indicated by the arrow, and duplicate sequences that formed part of an inter‐laboratory comparison are indicated with correspondingly colored symbols
