Phylogenetic analysis of SARS-CoV-2 viral genomes from domestic and international travelers. The 12 cases with sufficient viral genome coverage for phylogenetic analysis (≥90%) are highlighted by colored circles overlaying a global phylogenetic tree of 983 viruses, including 762 viruses in GISAID as of 20 March 2020 and the most recent viral genomes sequenced from California patients. The G, S, and V clades and the lineages dominated by genomes in Europe are highlighted. Abbreviations: GISAID, global initiative on sharing all influenza data; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
