COVID-19 and mutations a threat level assessment

31 Mar 2021

Abstract excerpt

A mutation is defined as an alteration in the DNA or RNA sequences of a genome which may consequently confer a new phenotypic and or genotypic advantage both increasing the virulence as well as the survival of a virus or pathogen. At this current point in time there are 4 known major variants of the original SARS-CoV-2 virus, namely the English variant (B.1.1.7), the South African variant (B.1.351), Brazilian...
