SARS-CoV-2 variants can rapidly come to dominate the global genomic landscape
The global distribution and estimated country-level proportions of deposited SARS-CoV-2 genomes for eight variants, shown for 1 November 2020 (top), 4.5 months later for 15 March 2021 (middle), and as of 1 August 2021 (bottom). Proportions over time are estimated from GISAID20 genome metadata, using a locally weighted multinomial regression model (see STAR Methods).
