Figure 1

Phylogenetic relationships inferred for subtype H3 hemagglutinin genes of 2 distinct lineages (indicated on the right of the tree) from influenza A viruses isolated from swine and humans at agricultural fairs in Ohio and Michigan, USA, 2016. Isolates recovered are shown as squares for swine and circles for humans; colors indicate the fair attended. Scale bar indicates nucleotide substitutions per site; collapsed clades within each lineage are monophyletic clades of swine H3 HA genes.
