For more than two years since the COVID-19 pandemic began, we have lived through different stages of it, as well as through different waves of infections which have usually been caused by variants of the original strain.

To know more about the variants it is very important to know their origin, that is why we will talk about in which countries they have emerged the most contagious variants and dangerous COVID.

Each of the variants has a series of mutations that are distinguished from each other, which has put scientists around the world in check and is that each one represents a different challenge. The most notorious and considered variants with a faster level of contagion are the Delta and Omicron, although now Centaurus is also being talked about.

Without a doubt, SARS-CoV-2 HAS had a large number of variants; nevertheless, we are going to focus on the origin of Delta, Omicron and the most recent, Centaurus.
