NEW YORK (CBSNewYork) — The holiday travel rush is underway as Americans deal with soaring COVID numbers — New York State just set a new record with nearly 22,000 positive tests.

AAA predicts 110 million Americans will ultimately travel this season, many undeterred by the rising coronavirus infections. But health officials warn this is the start of another wave, CBS2’s Christina Fan reported Sunday.

Millions of Americans are headed home for the holidays, packing airports and filling roadways at near pre-pandemic levels. Fears of an Omicron variant surge are not enough to stop people from traveling.

“It makes me nervous, but I’m boosted,” one traveler said.

COVID VACCINE

More than 2.2 million people passed through TSA security at airports across the country Friday, a jump of nearly 110% over last year.

More than one-third of the country is not fully vaccinated, let alone boosted.

“Are you worried about traveling safely with the Omicron variant spreading so quickly?” a traveler was asked.

“No, if I was I wouldn’t be going,” they said.

Delta is still the dominant variant fueling new infections in all but five states.

Health experts say the mutated Omicron variant is spreading fast and will soon overtake Delta. They fear the new strain will overwhelm health care systems in communities with low vaccination rates.

“Even if we have a spike or a surge that’s 25% of what it was last winter, we don’t have the capacity from space or staffing to deal with that,” said Dr. Thomas Yadegar of Providence Cedars Sinai Medical Center.

On Friday, new infections in New York surpassed 21,000. That’s the highest number of reported cases since the pandemic started and set up the second straight day with a new record.
