Phylogenetic analysis of U.S. SARS-CoV-2 Delta S:S112L sub-lineage isolates. Maximum-likelihood phylogeny inferred from 34 SARS-CoV-2 genomes analyzed in this study and 33 GISAID representative genomes belonging to the S:S112L sub-lineage using Wuhan-Hu-1 (GenBank sequence MN908947.3) as the reference. CO cluster isolates are highlighted, and branch-defining mutations labelled. Numbers at nodes represent > 80% bootstrap support. The scale bar represents the number of nucleotide substitutions per site
