Distribution of SARS-CoV-2 Omicron variant virus isolates clustered into 4 main clades, including viruses identified in this study from New York, New York, USA, November 25–December 11, 2021, and viruses from various regions as obtained from GISAID (https://www.gisaid.org). A) Clade A. B) Clade B. C) Clade C. D) Clade D. For viruses from GISAID, regions were divided into Africa, Asia, Europe, North America (excluding New York state), Oceania, South America, and New York State. Vertical gray dashed lines are to the left of the time at which viruses within the indicated clade were detected in the city of New York during this study.
