The delta variant of COVID-19 also known as B.1.617.2 is more contagious than the alpha variant and henceforth this variant has led to a sudden spike in the cases of COVID-19 all over the world. It is indeed a matter of surprise that in countries where most of the population were vaccinated, still there was an upturn in the number of COVID-19 infections. Though some of the vaccine companies have reported that their vaccine can effectively provide shielding against this variant too, but still we need to understand why is this variant more transmissible and how did it became a dominant strain in such a short span of time and what are the measures that can be taken to prevent the most widely spread delta-variant of this virus. An overall review regarding the delta B.1.617.2 variant along with its pathogenicity is done in this article.
