Coronavirus: the reason behind the continuing mutation of SARS-CoV-2


A virus tends to change constantly and this is well known. This coronavirus instead it caught us off guard by its ability to carry out this process at an astonishing speed. In a short time, different strains have appeared in the world, even quite different from each other and therefore with different peculiarities, the one that had become more contagious and the deadliest one.

The coronavirus SARS-CoV-2, also for this reason, it has become an important object of study and now a research team has tried to understand the reason behind this ability. It has been seen how he manages to accumulate approx two mutation every month, an impressive rate. The main motivation seems to be linked to the system of natural selection caused above all by the difference between vaccinated and unvaccinated population.

Coronavirus: the mutation capacity of SARS-CoV-2

The words of the researchers behind the study: “What we were seeing with the variants of SARS-CoV-2, particularly the disturbing variants, is that they have undergone many more mutations than we would expect with the normal evolutionary pace of similar coronaviruses. The number of mutations observed in these four VOCs is much higher than would be expected based on the phylogenetic estimates of the evolutionary rate of SARS-CoV-2 nucleotides. “

This is an explanation that doesn’t reveal everything, but it is enough to emphasize the importance of constantly monitor this coronavirus. Continuous analysis may actually help to uncover the spread of strains rather than others in advance. If at the moment we only remember a few, Omicron or Delta for example, in reality there have been many more.
