US coronavirus: ‘A natural disaster … in all 50 states’ is unfolding just as travelers disperse nationwide after Thanksgiving

“Here in Rhode Island, we are currently planning to open our field hospital on Tuesday because our hospitals are so full of sick Covid-19 patients. But not every state has that option,” she said.

“And even if you open a field hospital, if you have hundreds of staff who are sick — which is what many states across the country are currently facing — if you don’t have nurses and doctors and respiratory techs, even a field hospital isn’t going to save you. Our health care system is literally at the breaking point right now, thanks to Covid-19.”

New cases now mean new hospitalizations by Christmas

But it will be weeks before anyone knows how much of a role Thanksgiving gatherings and travel play in new hospitalizations and deaths.

“When you look at people who are hospitalized today, they were infected two weeks ago, maybe more,” said Dr. Jonathan Reiner, a professor of medicine at George Washington University. “And then it takes usually another week for folks to succumb to the illness.”

So infections picked up on Thanksgiving “are going to show up in three weeks and are going to show up in deaths over Christmas and New Year’s and are going to spread in every state,” Ranney said.

Statistics reported in the days after the holiday might show a relative dip in Covid-19 cases, followed by a surge due to a lag in government agencies’ reporting over the long weekend.

Even before then, Covid-19 is killing Americans at a staggering rate. At least 1,189 new deaths were reported on Saturday alone, according to Johns Hopkins University.

Birx: ‘If you’re young and you gathered,’ get tested

“If you’re young and you gathered, you need to be tested about five to 10 days later,” said Dr. Deborah Birx on CBS’s “Face the Nation” on Sunday. “You need to assume that you’re infected and not go near your grandparents and aunts and others without a mask.”

Birx, a member of the White House coronavirus task force, recommended those over age 65 get tested immediately if they develop any symptoms.

“If you’re over 65 or you have comorbidities and you gathered at Thanksgiving — if you develop any symptoms, you need to be tested immediately,” she said.

ER doctor wants people to follow stay-at-home orders

“What I wish is that people would follow those stay-at-home orders,” said Ranney, the emergency medicine physician in Rhode Island.

“I can’t tell you how many patients I take care of who tell me, ‘Well, I just went to an indoor restaurant.’ Or, ‘I just went to a party with a few friends. I didn’t actually think I was going to catch Covid.’ So those stay-at-home orders are critical.”

The Los Angeles County stay-at-home order prohibits all public and private gatherings with people outside a single household.

“Residents are advised to stay home as much as possible and always wear a face covering over their nose and mouth when they are outside their household and around others,” the county’s public health department said.

The order is in effect through December 20. It does not apply to “faith based services and protests, which are constitutionally protected rights,” the health department said.

Essential retail businesses will be limited to 35% occupancy, while the occupancy limit for nonessential retail operations, personal care services and libraries will be 20%, the county said.

“Even if you’re not feeling sick, the simple act of gathering with people outside your household puts everyone at risk,” county health director Barbara Ferrer said.

Ranney said it’s possible some schools and workplaces can operate safely if precautions are met.

“I think it’s really important that you keep safe workplaces and safe schools open,” she said. “We know that in those structured settings, where people are masked, keeping a distance, having adequate ventilation, the spread of the virus is pretty low in those settings,” she said.

“I am hopeful that that type of order will be effective. And we’ve seen in France that it works,” Ranney said. “I sure hope it will be (effective) in L.A., and I hope the rest of the country can follow suit. Because we need to do something, or — again — this virus is just going to just continue to grow out of control.”

That eclipses the previous California hospitalization record of 7,170 people on July 21.
