From: Comparison of genome replication fidelity between SARS-CoV-2 and influenza A virus in cell culture

Number of mutations including deletions and insertions per 105 nucleotides/passage. The average number of mutations after 15 serial passages of IAV and SARS-CoV-2 are shown. The vertical axis represents the number of mutations per 105 nucleotides per passage. IAV nucleotides include HA and NA gene sequences, and SARS-CoV-2 refers to S gene sequences. The bar plot represents the mean ± SD. ****p < 0.0001 (Mann–Whitney-U test).
