(A) MCC tree inferred for the five concatenated Eurasian origin gene segments (PB2, PA, HA, M, and NS) of the North America H5-clade 2.3.4.4 viruses containing H5N8 and H5N2 subtypes. The closest Eurasian strains inferred from supplemental Figure S2 are included in the analyses. (B) MCC tree inferred for the eight concatenated gene segments of North America H5N2 viruses of H5-clade 2.3.4.4. In both A and B, nodes are indicated by the solid circles and sized by posterior probability. The Canadian H5N2 outbreak viruses are coloured in the same manner as shown in (B).
