Omicron variant, in 20 nations, spread sooner than expected – .


Besides the question of the transmissibility of the Omicron, scientists still have no other answers the world is calling for: Are vaccines less effective against it? are treatments? Does Omicron cause more serious illnesses?

Experts have warned not to overemphasize reports that the variant causes only mild illness, as data is still scarce. Early evidence from South Africa indicates that Omicron, more than previous variants, is infecting people who had previously had Covid-19, but that too requires rigorous testing.

“It’s going to take two to four weeks, maybe a little sooner,” before preliminary answers are available, Dr. Anthony S. Fauci, America’s foremost infectious disease expert, said on Tuesday in a speech. briefing at the White House.

As of Tuesday evening, no cases of Omicron had been reported in the United States, although the variant was detected in Canada. U.S. officials say it’s only a matter of time and the goal should be to slow its spread.

Brazilian media reported on Tuesday that the variant has appeared in Brazil, which would mean that it is already present on all continents except Antarctica.

The US Centers for Disease Control and Prevention is sequencing the genomes of 80,000 coronavirus samples each week – about one-seventh of all positive PCR lab tests in the country – and will step up checks on international passengers on arrival , the agency’s director, Dr. Rochelle P. Wollensky, told the White House.
