Coronavirus: What's happening in Canada and around the world on Tuesday

The latest:

U.S. President Joe Biden on Monday pledged the full support of the federal government to states facing surges in COVID-19 cases from the more-transmissible omicron variant and a run on at-home tests.

Joining a regular meeting between his coronavirus response team and the National Governors Association, Biden said, "My message is: if you need something, say something, and we are going to have your back any way we can."

Biden acknowledged long lines and chaotic scenes as Americans sought out testing amid the case surge and as they looked to safely gather with family and friends over the holiday. He referenced his administration's plan to make 500 million rapid tests available to Americans beginning next month through an as-yet-to-be-developed website.

Meanwhile, Dr. Anthony Fauci, the top U.S. infectious disease expert, said Monday that the U.S. should "seriously" consider a vaccination mandate for domestic travel.

Speaking to MSNBC, Fauci, who serves as Biden's chief science adviser on the COVID-19 response, said, "When you make vaccination a requirement, that's another incentive to get more people vaccinated."

Canada currently requires people who are 12 years and four months or older to be fully vaccinated against COVID-19 to board domestic or international flights leaving from "most airports in Canada" as well as Via Rail or Rocky Mountaineer trains.

The U.S. currently mandates that most foreign nationals travelling to the U.S. be fully vaccinated against the coronavirus, but has not instituted one for domestic travel.
