A Brief Review on Viral Variants of COVID-19 Infection

SARS is a type of acute respiratory syndrome. Coronavirus 2 (SARSCoV2), highly contagious, affecting people worldwide. Coronavirus Disease 19 (COVID19) leads to a rapidly spreading respiratory distress syndrome. It has caused a global pandemic and severe health crisis in most countries. Due to its continual evolution, further research into the virus's pathogenicity and virulence mechanisms and the development of efficient therapy techniques are urgently required. The current paper summarises what is known about the virus's evolutionary and structural features to comprehend better its mutational pattern and probable role in the current pandemic. In December 2019, the Coronavirus Disease (SARSCoV2) began a destructive path toward a global pandemic in Wuhan, China. Since then, several SARS CoV2 variants have been discovered. Despite the speedy development of a COVID19 vaccine and ongoing mass vaccination efforts around the globe, the discovery of the latest SARSCoV2 variants could undermine the substantial success till now in stopping the spread of SARSCoV2.This review aims to characterize the different SARS CoV2 mutations and investigate the associated morbidity and death.

Due to the virus's steady improvement, with its various unmarried nucleotide polymorphism (SNP) versions and lineages, figuring out SARS-CoV-2 infectivity is extraordinarily hard. but, similarly research into the virus's pathogenicity and virulence mechanisms, as well as the improvement of green therapy strategies, is urgent present-day The present day contribution summarises existing expertise regarding the virus's evolutionary and structural homes to clarify its mutational sample and ability function inside the ongoing pandemic.
