Characterization of circulating RSV strains among subjects in the OUTSMART-RSV surveillance program during the 2016-17 winter viral season in the United States
Fig 3
RSV A and B genotypes of 2016–17 OUTSMART samples by geographic region.
The phylogenetic tree in the left panel was built using the representative G protein sequences from 97%-identity clusters, with the horizontal scale under the tree showing branch lengths derived from the dissimilarity metric. The corresponding bars in the right panel represent the number of samples in each cluster, with horizontal scale under the bar plot showing sample counts.
