Changes in nucleotide sequence frequency at five selected SARS-CoV-2 genomic positions during the coronavirus disease (COVID-19) pandemic. The frequencies of 2480A (blue), 2558C (orange), 3037T (grey), 14408T (yellow), and 14805C (green) in England (A), Spain (B), Asia (C), and USA (D) are shown. Lines for nucleotides 2480 and 2554 and those for nucleotides 3037 and 14,408 mostly overlap as they correspond to associated sequence variations. Whole-genome SARS-CoV-2 sequences used in this analysis were downloaded from the GISAID database [48].
