Surging COVID-19 cases bring a 2020 feel to the end of 2021

US officials intensified calls Friday for unvaccinated Americans to get inoculated in the face of the new omicron variant that contributed to a record number of infections in New York and threatened to wipe out a second holiday season in Europe.

Though the calendar is about to change, Friday had a distinctly 2020 feel: NFL games were postponed because of COVID-19 infections. The Rockettes Christmas show was canceled for the season. European governments imposed a spate of restrictions that ground travel to a halt and saw travelers lying low.

Much remains unknown about omicron, but officials warn that it appears more transmissible than the delta variant, which has already put pressure on hospitals worldwide. The uncertainty alone was enough for many people to change their plans.

In the United States, President Joe Biden’s administration resisted tightening any restrictions, but also sketched out dire scenarios for the unvaccinated in a plea for hesitant Americans to get the shot.

“For the unvaccinated, you’re looking at a winter of severe illness and death, for yourselves, your families, and the hospitals you may soon overwhelm,” White House coronavirus response coordinator Jeff Zients said Friday, echoing the president’s own comments earlier this week.

The new variant is already in “full force” in New York City, Mayor Bill de Blasio said, with new cases hitting a one-day record of more than 8,300 on Thursday. But new hospitalizations and deaths – so far – are well below their spring 2020 peak and even where they were this time last year, city data shows.

The coronavirus also interrupted sports in the U.S. again. The NFL announced Friday that three games would be pushed from the weekend to next week because of outbreaks. The league has not specified whether the cases came from the omicron variant.

The Radio City Rockettes called off four performances scheduled for Friday because of breakthrough COVID-19 cases in the production, and plans for upcoming shows were still being assessed. The popular holiday program generally has four shows per day in December at Radio City Music Hall in Manhattan.

Dr. Stanley Weiss, a Rutgers University epidemiology professor, said officials need to react faster, citing a willingness to redefine fully vaccinated to include booster shots, for example.

“Everyone wants us to be through with this pandemic, but in order to get us through it, we can’t ignore the realities of what’s going on and what is needed,” Weiss said.

Denmark decided to close theaters, concert halls, amusement parks and museums in response to virus cases. In Spain, friends and classmates canceled traditional year-end dinners.

Scotland and Wales on Friday pledged millions of pounds for businesses hurt in Britain’s latest infection surge, a move that heaped pressure on Prime Minister Boris Johnson’s government to do the same in England.

Treasury chief Rishi Sunak held talks with business representatives who have demanded more support, decrying a “lockdown by stealth” in which government officials recommend people cut back on socializing as much as possible without officially imposing the strict rules of past shutdowns.

Britain reported record numbers of infections three days in a row this week, the latest on Friday with more than 93,000 cases tallied.

Businesses ranging from vacation providers to pubs and theaters saw a wave of cancellations as customers decided to skip merrymaking for now rather than risk being infected and missing family celebrations later.

Even Britain’s Christmas pantos — beloved and raucous holiday performances — are under threat. The Belgrade Theatre in Coventry in western England had to refund 180,000 pounds ($240,000) in ticket sales after customers decided not to go to shows. It was also forced to cancel 12 performances of “Beauty and the Beast” because half the cast tested positive.
