Abstract
COVID-19, a trending thread to the present world is not a single type of virus, instead it's a group of virus which genetic material is single stranded RNA molecules that can easily make more and more copies which help the virus particles to be spread out in a large population. Starting its journey in December, 2019 from China as SARS-CoV-2 it have already showed several strains with various type of infectivity and till today it is running its Kingdom. Coronavirus contain various strains such as Alpha, Beta, Gamma, Delta, Epsilon, Eta, Zeta, Iota, Theta, Kappa and Lambda in which Alpha, Beta, Gamma and Delta are variant of Concerns (VoCs) which means they are more developed in transmissibility, infectivity and decreasing the effectiveness of vaccines and other strains are known as Variant of Intarest (VoIs) which means this strains are in dormant state but anytime they can be converted into VoCs. These variants Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1) and Delta (B.1.617.2) had already run over their kingdom and now it's the of omicron the trending (B.1.1.529). Though all of this strains are of coronavirus but they are not similar in character, they are different either in transmissibility or in severity. This present study is all about the comparison of the VoCs of COVID-19.
