Covid has mutated

And is now the predominant form infecting people according to the latest.

"Many uncertainties remain about the mutated form of the new coronavirus that has been under study as it quickly spreads. But one question about G614 has been resolved, researchers said Thursday. 'This is now the virus,' said Erica Ollmann Saphire, who worked on a study published in Cell, reports CNN. 'It is now the dominant form infecting people,' she said, having supplanted D614, which first went through Europe and the US. Some earlier impressions of the mutation are unchanged: Genetic sequence work and experiments conducted by an international team, which reported partial findings earlier in the year, support the indications that G614 is more likely to infect people but isn't necessarily more dangerous to them. 'We do know that the new virus is fitter,' said Saphire, of the La Jolla Institute for Immunology. 'It doesn't look at first glance as if it is worse.'"
