Corona Virus mutations and variants—what do we know?

Viruses mutate, and SARS-CoV-2 is no exception. Throughout the current global crisis, SARS-CoV-2 has been mutating at a rate of about 1–2 mutations per month [1]. Some recent emerging variants, however, have accumulated significantly more mutations in short periods of time, causing concern around the globe [2]. Scientists predict that these mutant lineages of the SARS-CoV-2 strain will not be the only concerning variants that emerge, as continued uncontrolled transmission of SARS-CoV-2 in many parts of the world and selective pressures, such as vaccines, are creating ideal conditions for additional, significant virus evolution [3].
