Figure. Phylogenetic reference tree of clade IIb monkeypox virus sequences as of October 2023 from study of real-time use of mpox genomic surveillance, King County, Washington, USA, 2022–2024. The tree shows the viral strain of sublineage A.2.1 identified from a King County, Washington, resident in August 2023 (in red) is highly diverged from the B.1 lineage. Colors correspond to the location of the case from which a viral isolate was sampled and are either a region, the United States, or King County, Washington, for the specific isolate of interest in this case report. Phylogenetic tree generated in NextClade (https://clades.nextstrain.org) as the global reference tree for monkeypox viruses in clade IIb. The reference sequence used in the tree is the clade IIb National Center for Biotechnology Information reference sequence NC_063383.1. Additional annotation added using Auspice version 2.49.0 (https://github.com/nextstrain/auspice.us).
