From: Maast: genotyping thousands of microbial strains efficiently
Application of Maast to track SARS-CoV-2 diversification from Dec 2019 to July 2020. a Genetic distances of SARS-CoV-2 strains over time compared to one of the earliest SARS-CoV-2 strains (Accession #: NC_045512). b Median genetic distance of SARS-CoV-2 in a country is strongly correlated with average sampling day gap. c Subspecies structure of SARS-CoV-2 over time. Each dot is a SARS-CoV-2 strain, colored by sampling month with other time points in gray. Dimension reduction and visualization were performed with UMAP. Nearby samples in UMAP space have similar genotypes
