While the spread of the Omicron variant around the world gives hope an imminent end to the coronavirus pandemica new variant of the virus was discovered by American researchers on living rats in the sewers of New York.
It is indeed a study carried out by several American universities and published in the review Nature on February 3, 2022 which brought this discovery to light. Relayed by The Independent, the study argues that no real evidence seems to show that the circulation of this variant occurs in rats, but “one of the amino acid changes that we observe in the virus was not observed in patients Never. But this change has been observed in a rodent-adapted virus“, according to one of the researchers.
According to them, the future variant could certainly emerge in rats first: “The observation is consistent with the possibility that these lines are derived from a animal host such as a rodent“, concludes the study. It must be said that the coronavirus should continue to spread in increasingly contagious but less serious forms, which is why there is no need for concern at the moment.
