The ongoing Covid-19 pandemic has grappled the world with fear, infecting around 18.2 Cr people and resulting in the deaths of 39.5 L in the span of a mere eighteen months (until July 2021). First identified as the cause of a cluster of pneumonia cases in Wuhan, China in 2019, Covid-19 is now proving to be a complex and long-lasting challenge for everyone. Just as any other virus, SARS-CoV-2 also mutates all the time, it has been acquiring minor random mutations ever since it jumped from animal (bat) to humans. These constant mutations are creating new variants and are posing a challenge to scientific efforts all over the globe. The aftermath is especially felt in the United Kingdom (with the B.1.1.7 variant), India (B.1.617), and Brazil (P1). Despite the extraordinary speed of vaccination and other drug discoveries against the novel corona virus, these variants continue to threaten mass destruction. This article describes SARS-CoV-2, its dominant variants (α, β, γ), associated mortality rate, epidemic, and prevalence factor, how immune system reacted to different variants and the current treatment available.
