Figure 1. Markov Chain Monte Carlo (MCC) time-scaled phylogeographic tree and phylogeographic map of global downsampled Influenza A virus (IAV) sequences. (1.a) Phylogeographic tree, color-coded by geographic source region. Grey branches indicate historical sequences between 1978 and 2008 which contributed to the overall tree structure but were masked from phylogeographic analyses (Gass J.D., 2021). (1.b) phylogeographic map of global downsampled IAV sequences, color-coded by geographic source region. 95% HPD tree and posterior value support can be found in Supplementary figure 4.
