Different scenarios explaining the emergence of novel variants of concern (VOC) of the
severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported …

Long-term severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in
immunodeficient patients are an important source of variation for the virus but are …

Although most mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-
CoV-2) genome are expected to be either deleterious and swiftly purged or relatively …
