Phylogenetic analysis of SARS-CoV-2 sequences. In total, 858 sequences, including 286 sequences from isolates from Korea, were used to construct the tree. All sequences were aligned to the Wuhan-Hu-1 reference sequence using Geneious Prime software (https://www.geneious.com/) and then manually trimmed to equal lengths. A maximum-likelihood phylogenetic tree was reconstructed using FastTree under the GRT+γ nucleotide substitution model, and the phylogenetic tree was visualized using iTOL (https://itol.embl.de/).
