Maximum clade credibility trees for co-circulating influenza A virus H7 subtype genetic lineages, eastern Asia. A) Clade A. B) Clade B. Values along the branches are posterior probability values >0.8. Gray bars indicate 95% highest posterior density for times of the most recent common ancestors; blue indicates viruses isolated in Asia; green indicates  viruses isolated in Europe (details on locations and associated posterior probabilities are shown in the online Technical Appendix, wwwnc.cdc.
