SARS-CoV-2: Genetic variability, mutations and variants of concern for the global world

Since emerging from Wuhan, China, in December of 2019, the novel coronavirus named SARS-CoV-2 has been causing devastating severe respiratory infections in human population worldwide. The new emerging disease was called COVID-19 and, as early as the beginning of 2020, the world found itself in a COV...

The new emerging disease was called COVID-19 and, as early as the beginning of 2020, the world found itself in a COVID 19 pandemic.
