Figure 2

Time-scaled phylogenetic tree of complete GII.P16 polymerase nucleotide sequences constructed using the Bayesian MCMC method (BEAST v1.10.4) using the GTR + G + I substitution and uncorrelated relaxed clock model. Viruses in the Novel GII.P16 lineage were first detected in 2014 diverging from a common ancestor with Extant B GII.P16 viruses that were first reported in 2010. Viruses in the Extant A GII.P16 lineage were detected from 1975 to 2015. Figure includes all sequences from GenBank (Table S1) and CDC-generated (Table S2) included in this study.
