Abstract:
SARS-CoV-2, like other RNA viruses, is susceptible to genetic evolution, with mutations forming over time, resulting in mutant strains with differing characteristics from the original strains. With so many variants discovered the CDC and WHO created its own classification system for SARS-CoV-2 variants, dividing them into variants of concern (VOCs) and variants of interest (VOIs). Convalescent plasma, antiviral medicines, dexamethasone, monoclonal antibodies, and immuno modulators, which are currently available to treat SARS-CoV-2 infection, could help manage SARS-CoV2 infection, although their effectiveness is limited. COVID-19 vaccines have been created in a variety of techniques, all of which are briefly discussed in this article. The development of affordable and effective oral anti-COVID-19 drugs along with increased vaccination uptake, will go a long way toward not just reducing COVID-19's progression but also bringing hope for the end of this devastating pandemic caused by Covid 19. The rationale of this study is to give a comparison of the many Covid strains that exist around the world.
