Resumen
The appearance of mutations is a natural and expected event within the evolution of the virus. Since the initial genomic characterization of SARS-CoV-2, the virus has been divided into different genetic groups or clades. In fact, some specific mutations define the viral genetic groups (also called lineages) that are currently circulating globally. La aparición de mutaciones es un evento natural y esperado dentro del proceso de evolución de los virus. Desde la caracterización genómica inicial del SARS-CoV-2, este virus se ha dividido en diferentes grupos genéticos o clados. De hecho, algunas mutaciones específicas definen los grupos genéticos virales (también denominados linajes) que circulan actualmente a nivel global.
