of COVID-19, the appearance and spread in the world of variants of the New Coronavirus SARS-CoV-2 have raised further concerns among people around the globe.
All viruses, especially RNA viruses such as SARS-CoV-2, continually tend to mutate their genetic material to form new variants of themselves; this behavior is justified in the fact that varying could give them characteristics that improve their survival, pathogenicity, transmissibility or the ability to circumvent acquired immunity (obtained from a previous infection or through a vaccine).
Clearly, the variations that arise from the tendency to change are not always functional; very often, indeed, the product of the mutation does not bring particular benefits.
This article basically aims to analyze which mutations characterize the current variants of SARS-CoV-2; for a better understanding of the content, of course, within it, it also includes a brief review of the reference structure of the New Coronavirus.
