The U.S. is facing its second Thanksgiving of the pandemic in better shape than the first time around, thanks to the vaccine, though some regions are seeing surges of COVID-19 cases that could get worse as families travel the country for gatherings that were impossible a year ago.

Nearly 200 million Americans are fully vaccinated. That leaves tens of millions who have yet to get a shot in the arm, some of them out of defiance. Hospitals in the cold Upper Midwest, especially Michigan and Minnesota, are filled with COVID-19 patients who are mostly unvaccinated.

Michigan hospitals reported about 3,800 coronavirus patients at the start of the week, with 20% in intensive care units, numbers that approach the bleakest days of the pandemic’s 2020 start. The state had a seven-day new-case rate of 616 per 100,000 people Monday, highest in the nation.

In the West, New Mexico, Arizona, Colorado, Utah and Montana also ranked high. Some Colorado communities, including Denver, are turning to indoor mask orders to reduce risk, a policy that has also been adopted in the Buffalo, New York, area and Santa Cruz County, California.

The statistics in Michigan are “horrible,” said Dr. Matthew Trunsky, a respiratory specialist at Beaumont Health in suburban Detroit.

“We got cold and moved indoors and have huge pockets of unvaccinated people,” he said. “You can’t have pockets of unvaccinated people who don’t want to be masked and not expect to get outbreaks, not expect to lose parents, not expect to lose teachers.”

During a recent office visit, he encouraged a patient who uses oxygen to get vaccinated. The patient declined and now is in the hospital with COVID-19, desperately relying on even more oxygen, Trunsky said.

He said he continues to encounter patients and their family members espousing conspiracy theories about the vaccine.

“We’ve had several people in their 40s die in the last month — 100% unvaccinated,” Trunsky said. “It’s just so incredibly sad to see a woman die with teenagers. Especially with that age group, it’s nearly 100% preventable.”

In Detroit, where less than 40% of eligible residents were fully vaccinated, Mayor Mike Duggan said hospitalizations have doubled since early November.

“We have far too many people in this country that we have lost because they believed some nonsense on the internet and decided not to get the vaccine,” said Duggan, a former hospital executive.

Despite hot spots, the outlook in the U.S. overall is significantly better than it was at Thanksgiving 2020.

Without the vaccine, which became available in mid-December 2020, the U.S. a year ago was averaging 169,000 cases and 1,645 deaths per day, and about 81,000 people were in the hospital with COVID-19. The U.S. now is averaging 95,000 cases, 1,115 deaths and 40,000 in the hospital.

Airports have been jammed. More than 2.2 million people passed through security checkpoints last Friday, the busiest day since the pandemic shut down travel early in 2020. On some recent days, the number was twice as high as Thanksgiving a year ago.

Sarene Brown and three children, all vaccinated, were flying to Atlanta from Newark, New Jersey, to see family. People close to them have died from COVID-19.

“I’m thankful that I’m here, and I’m not in heaven, and I’m thankful for my family and that God helped me survive,” said Neive Brown, 7, who got her first dose.

More than 500,000 Americans have died of COVID-19 since the last Thanksgiving, for an overall death toll of more than 770,000.

“We would encourage people who gather to do so safely after they’ve been fully vaccinated, as we’ve been saying for months now,” said Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention. “I do think that this is very different because we actually have the tools to prevent the vast majority of cases.”

Dr. Eric Topol, head of the Scripps Research Translational Institute, said his optimism is tempered by the delta variant’s ability to jump from person to person, especially among the millions who are unvaccinated or are due for a booster.

“That equals very high vulnerability,” Topol said.

Denver’s public hospital, Denver Health, is sending people elsewhere because of a lack of beds. Staff members were exhausted from treating COVID-19 patients and others who had postponed other medical needs, chief executive Robin Wittenstein said.

“Our system is on the brink of collapse,” she said.

Arizona reported at least 2,551 COVID-19 patients in hospitals, far below the peak of last winter but still reason for concern. Officials said beds were limited.
