Covid :: mutations, effects, speed of propagation. Here is the new photograph of the virus

It took 300,000 genomes to take the photograph of the real-time evolution of Covid-19. The study by six American researchers published in Pnas, US scientific journal and official organ of the United States National Academy of Sciences, unveils the mechanisms of the virus that, in just over a year, has put the world in check. He discovers its origins through the first mutations, one of which identified in distant Oceania; brings to light evidence that goes beyond the traditional view that the key to defusing it lies only in the Spike protein; it identifies the movements between continents and the phases of growth, stagnation and recovery; suggests a new way to attack him: not just sequencing, but …
