SARS-CoV-2 variants arise during individual infections

Early in the COVID-19 pandemic, SARS-CoV-2 genome variation appeared to be low, with an average of 10 base differences in the 30,000 base genome between any two isolates. Late in 2020, as many more people were infected, variants were isolated that had more changes than previously seen. A study of variation at the genome level […]
