(A) Time-scaled phylogenetic tree inferred using Bayesian MCMC analysis for HA gene of H5-clade 2.3.4.4 viruses. Nodes and branches are coloured according to clusters formed. North America H5-clade 2.3.4.4 viruses are highlighted in magenta. Nodes are indicated by the solid circles and sized by posterior probability. Fully annotated tree is available in Supplemental Figure 1. (B) Close-up of cluster III (3) from A with name of viruses labeled. British Columbia (BC) H5N2 outbreak viruses are shown in red and Ontario H5N2 outbreak viruses in blue.
