Researchers have often asked themselves during this pandemic: Will mutations make the Sars-Cov-2 coronavirus more adaptable to its host, that is, to the human being, and consequently less infectious or not? The tests are different, and not always in line with each other. Now an extensive study, recently conducted by University College London, on a sample of over 46 thousand viral genomes from around the world, shows that more frequent mutations of the virus do not increase its transmissibility. So for now, they are not responsible for the increase in infections. But the debate on this issue is still open. In general, viruses can show more or less significant changes during their reproduction, and can diversify into distinct viral strains (or subtypes) after many reproductions, especially when they spread widely in a population.
But scientists say that doesn't necessarily Cambodia WhatsApp Number Data mean increased transmissibility or risk. The proof is the result of the latest study: the mutations traced in the many genes of Sars-Cov-2, do not indicate a greater infectivity of the coronavirus. Researchers reached these conclusions after analyzing viral genomes obtained from more than 46,000 patients from 99 countries around the world. The analysis shows that there were different mutations: the authors counted 12,706 of them, of which about 400 are repeated more often. So they appear repeatedly and independently in patients from different countries of the world. Among these, the researchers focused on 185 mutations that were recorded in at least 3 different and independent cases throughout the pandemic.
The authors of the study tried to understand if some of these modifications could have the effect of a greater transmissibility of the infection. For this, they created a model and mapped the evolutionary tree of the virus – which somewhat resembles our family tree – by analyzing whether any of the branches of this tree, starting from the known mutations, had evolved more than the others.

Antibiotics are given as "candy", risking a public health disaster One of the mutations most often observed on a large scale involved the protein that coats the outside of the coronavirus, and has been labeled D614G. But according to the latest study, it is also harmless, and does not appear to have increased the transmissibility of Sars-Cov-2.
