Eurasian clade of the phylogenetic tree for all full-length H6 sequences of avian influenza virus (excluding multiple sequences of the same isolate). Black branches indicate isolates from North America, and gray branches indicate isolates from Eurasia. The 7 subclades that invaded North America and their closest Eurasian related clade and bootstrap values are shown on the right. Abbreviations for strain names are listed in the Technical Appendix Table.
