An increasing number of governors and mayors across the U.S. are ratcheting up COVID-19 restrictions ahead of Thanksgiving for fear that holiday travel and family gatherings will only worsen the record-breaking, coast-to-coast resurgence of the virus.

In states like New Mexico and Washington and cities such as Philadelphia and Chicago, leaders are ordering or imploring residents to stay home and keep their distance from others to help stem a rising tide of infections that threatens to overwhelm the health care system.

“I must again pull back the reins,” New Jersey Gov. Phil Murphy said Monday. “It gives me no joy.”

The tightening came as Moderna Inc. announced that its experimental coronavirus vaccine appears to be over 94% effective, based on early results. A week ago Pfizer disclosed similar findings with its own formula.

The news raised hopes that at least two vaccines against the scourge could win emergency authorization and become available in the U.S. before the end of 2020.

A record-breaking nearly 70,000 people were hospitalized with the coronavirus in the U.S. as of Sunday, 13,000 more than a week earlier, according to the COVID Tracking Project. Deaths in the U.S. are running at more than 1,100 per day on average, an increase of over 50% from early October.

The virus is blamed for more than 246,000 deaths and over 11 million confirmed infections in the the U.S.

Murphy on Monday said he is tightening the limits on indoor and outdoor crowds. The Democrat acknowledged that restricting indoor gatherings to 10 people, down from 25, will lead to frustration but said that little about this year has been normal.

New Mexico Gov. Michelle Lujan Grisham’s stay-at-home order went into effect Monday. Only essential businesses, including grocery stores and pharmacies, will be open.

Washington’s Democratic Gov. Jay Inslee ordered gyms, bowling alleys, movie theaters, museums and zoos to shut down indoor operations. Stores must limit capacity to 25%.

People from different households will be barred in Washington from gathering indoors unless they have quarantined. There is no enforcement mechanism. Inslee said he hopes people obey anyway.

Chicago Mayor Lori Lightfoot called on residents in the nation’s third-largest city to restrict social gatherings to 10 people starting Monday. In instructions that were advisory, not mandatory, she urged residents to stay home except for essential activities, like going to work or grocery shopping.

Philadelphia banned all indoor dining at restaurants and indoor gatherings of any size, public or private, of people from different households, starting this Friday.

In Michigan, Democratic Gov. Gretchen Whitmer warned she has the authority to issue a second stay-at-home order to curb the spiking coronavirus if necessary and said it was “incredibly reckless” for President Donald Trump’s science adviser Scott Atlas to urge people to “rise up” against Michigan’s latest restrictions.

Over the weekend, Whitmer announced that Michigan high schools and colleges must halt in-person classes, restaurants must stop indoor dining and entertainment businesses must close for three weeks. Gathering sizes also will be tightened.

Fourteen men were charged earlier this fall in an alleged plot to kidnap the governor in anger over her COVID-19 restrictions.

Atlas later tweeted that he “NEVER” would endorse or incite violence.

Even North Dakota Republican Gov. Doug Burgum, who has resisted a mask mandate for months, put one in place over the weekend, amid a severe outbreak in the state.

Still, several other GOP governors were taking incremental steps, or resisting even those — continuing to emphasize “personal responsibility” rather than government edicts.

Texas Gov. Greg Abbott in recent days has been emphasizing that new treatments and vaccines are expected to become available soon.

Vice President Mike Pence sounded an upbeat tone Monday on a call with governors, saying that the government is ready to help states where hospitals are nearing capacity and emphasizing that vaccines are coming.

“America has never been more prepared to combat this virus,” he said.
