Joe Biden came back from his Thanksgiving break to hold an emergency assembly with his COVID advisors on Sunday evening. Dr. Anthony Fauci suggested that it will be two weeks until the new variant, Omicron, is fully understood and that he believed "existing vaccines are likely to provide a degree of protection against severe cases" from the super-strain variant.
Two cases of Omicron were verified in Canada on Sunday - both in patients in the capital, Ottawa, who had moved to Nigeria. Nigeria is not on the list of countries influenced by Biden's travel ban, announced on Friday, which came into effect at 12:01 ET on Monday.

Updates on those patients' circumstances have not been shared. Upon returning from Massachusetts, Biden was asked whether he was weighing further travel limitations.
"I'm having a meeting with my medical team as I get back to the White House. I'll have more to say," he said.

The White House then published a photo of Biden sitting in the Oval Office with Fauci, his Chief Medical Advisor; his Chief of Staff, Ron Klain; Jeff Zients, White House Coronavirus Response Coordinator; and two others.

"Following up on the regular briefings he had on COVID while traveling, the President met in person today with his Chief Medical Advisor, Dr. Anthony Fauci, and members of his White House COVID Response Team on the latest developments related to the Omicron variant," the White House said.

"Dr. Fauci informed @POTUS that while it will take approximately two more weeks to have more definitive information on the transmissibility, severity, and other characteristics of the variant, existing vaccines are likely to provide a degree of protection against severe cases.

"Dr. Fauci also reiterated that boosters for fully vaccinated individuals provide the strongest available protection from COVID. The COVID Response Team's immediate recommendation to all vaccinated adults is to get a booster shot as soon as possible."

Yet despite the White House's concern, there are no new rules on testing before or after travel.
Airline passengers entering the United States from abroad must prove that they are vaccinated before they board, but are not regularly observed by health officials after they leave flights and are not required to take a COVID-19 test upon entry in the United States.
Americans do not need to be vaccinated to return home, but they must usually provide a negative COVID test, taken no more than 72 hours before, to fly.
Americans can still fly from the "banned" countries.
