Biden told it will take two weeks to have definitive data on Omicron variant

WASHINGTON, Nov 28 (Reuters) - The top U.S. infectious disease official, Dr. Anthony Fauci, told President Joe Biden on Sunday it will take about two weeks to have definitive information on the new coronavirus variant Omicron that has sparked new travel restrictions and shaken financial markets.

Biden, returning to Washington following the Thanksgiving holiday weekend, was briefed in person by his coronavirus response team on Sunday afternoon as officials expect the new variant to reach the United States despite an impending ban on travelers from Southern Africa, where it was first detected.

Fauci said he believes existing vaccines are likely to provide "a degree of protection against severe cases of COVID", and officials reiterated their recommendation for vaccinated Americans to get booster shots, according to a readout of the briefing.

Biden was due to update the public on the new variant and the U.S. response on Monday, the White House said.

Omicron https://www.reuters.com/world/new-coronavirus-variant-omicron-keeps-spreading-australia-detects-cases-2021-11-28, which was first detected in Southern Africa, has now been confirmed in Australia, Belgium, Botswana, Britain, Denmark, Germany, Hong Kong, Israel, Italy, the Netherlands, France, South Africa, and the United States' neighbor to the north, Canada.

Earlier on Sunday, Fauci told ABC News' "This Week" that the new variant would "inevitably" reach the United States.

U.S. health officials were to speak with counterparts in South Africa to get "more information in real time," Fauci told NBC, adding the flight curbs would give them more time to gather information and weigh possible action.

"It clearly is giving indication that it has the capability of transmitting rapidly. That's the thing that's causing us now to be concerned," he added on NBC.

Its appearance in the United States, where 30% of the population has not received a single dose of vaccine https://tmsnrt.rs/3FSkZ03, could threaten to undermine the nation's recovery nearly two years after COVID-19's emergence and further pressure local healthcare systems already taxed by the recent Delta variant.

Rising cases as colder weather forces more people indoors has also caused some hospital systems and U.S. states, including New York, to declare emergencies.

So far, nearly 782,000 people have died in the United States from COVID-19 since early 2020, the most of any country in the world, amid over 48 million infections, Reuters data show.

TRAVELERS BANNED, NOT FLIGHTS

The United States is joining other nations in seeking to block transmission by imposing travel restrictions.

Beginning at 12:01 a.m. ET (0501 GMT) on Monday, it will bar entry of nearly all foreign nationals who have been in any of eight southern African countries within the last 14 days and has warned Americans against traveling to those nations. U.S. citizens who have traveled to the countries will still be able to enter the United States.

Flights by Delta Air Lines (DAL) and United Airlines have continued https://www.reuters.com/business/aerospace-defense/delta-united-not-revising-south-africa-flights-amid-variant-concerns-2021-11-26 from South Africa to the United States since the variant was discovered. Passengers interviewed by CNN as they arrived on flights from southern Africa at two U.S. airports - one in Atlanta and the other at Newark - said they were not subject to any specific checks or restrictions.

Fauci and other top officials said the sudden burst of cases made Omicron worrisome and it remained unclear how current vaccines or therapeutics could be impacted.

"We need more data there before we can say confidently that this is not a severe version of the virus, but we should find that out in the next couple weeks," outgoing National Institutes of Health Director Dr. Francis Collins told "Fox News Sunday."

Vaccine makers Pfizer/BioNTech and Moderna (MRNA) have said they expect more information soon.

"We have to go through a couple of weeks yet of uncertainty," Moderna (MRNA) Chief Medical Officer Dr. Paul Burton told CNN, saying Omicron's transmissibility and severity were also still unknown along with current vaccines' effectiveness against it.

'CLARION CALL' FOR SHOTS

Fauci pressed Americans to continue to get COVID-19 vaccines and boosters while experts evaluate Omicron.

"This is a clarion call...(to) get vaccinated," he told NBC.

The United States has recorded over 1.1 million new COVID-19 cases in the last 14 days, up 9% from the prior two weeks, Reuters data shows, with Michigan and Minnesota leading the nation in new cases, based on infections per 100,000 residents.

The governor of one hard-hit state, Arkansas' Asa Hutchinson, expressed worry over another blow from the latest variant, telling CNN's "State of the Union" program: "Delta has been tough on us. And so we don't welcome a new variant. And it is a great concern."

The variant could cast a pall over the rest of the U.S. holiday season and potentially impact companies' return-to-office plans depending on what officials discover in coming weeks. A number of banks and other firms have said they planned for workers to come back in January.

On Wall Street, sources at major U.S. banks and European banks with large U.S. operations said they were not yet changing their policies but were monitoring the situation.
