The National Football League is closing all team facilities to in-person activities on Monday and Tuesday.

The ban doesn't apply to teams scheduled to play on those days, including a Steelers-Ravens game on Tuesday that's already been rescheduled twice.

The NFL cited in a league-wide memo rising COVID-19 cases in the U.S. and the "understanding that a number of players and staff celebrated the Thanksgiving holiday with out-of-town guests" as reasons for the closures.

Public and private gatherings with those outside your household will be prohibited in Los Angeles County starting Monday under a new public health order.

Playgrounds and cardrooms will also close, among other restrictions.

Religious gatherings and protests are exempt from the temporary order, which will remain in effect through Dec. 20.

The measures come as the county continues to see "alarming levels" of new COVID-19 cases and increasing hospitalizations, the Los Angeles County Department of Public Health said.

As of Wednesday, outdoor dining in the county is on pause for the next three weeks.

Officials had warned additional lockdown measures would come once the five-day average of cases reached 4,500. On Friday, that number was 4,751.

More than 13 million people have tested positive for COVID-19 in the U.S., according to Johns Hopkins University.

The U.S. crossed 12 million cases six days ago.

Experts have cautioned against reading too much into data reported before next week, as some state updates may be spotty due to the Thanksgiving holiday.

Vermont officials are urging people who had Thanksgiving gatherings with those outside their household to now quarantine.

“My request to Vermonters who may have participated in travel and/or multi-household gatherings is simply this: Please quarantine yourselves at home, and please get tested now and in seven days,” state Health Commissioner Dr. Mark Levine said during a press briefing Friday.

Gov. Phil Scott echoed the health commissioner’s request.

“If you have had one of those gatherings yesterday, then you shouldn't send your kids to school next week," he said. "You should quarantine your kids for at least seven days, get a test, and then we'll move forward."

Scott said earlier in the week that school officials will ask returning students if they attended a Thanksgiving gathering with people outside their household to determine quarantine requirements.

"We did all of this to try and protect Vermont, to try and prevent the rise in the number of cases," Scott said Friday.

A COVID-19 patient whose lungs had been severely damaged by the virus has made a miraculous recovery after undergoing a double lung transplant at a Texas hospital.

Paul Rodriguez, 52, of San Antonio, had no pre-existing conditions when he contracted the novel coronavirus and fell ill with pneumonia in July. Rodriguez was hospitalized at an area hospital in his hometown and required intubation as well as the use of a ventilator. Then in mid-September, Rodriguez was transferred to Baylor St. Luke's Medical Center in Houston for evaluation, "as it became clear that a lung transplant was his only chance of survival," according to a press release from the hospital, which said the patient had "irreversible lung damage."

Rodriguez was approved for a transplant and, within a week of listing, he received a brand-new set of lungs on Oct. 15. After being successfully weaned off the ventilator and oxygen support, Rodriguez underwent rehabilitation at Baylor St. Luke's Medical Center and was discharged on Nov. 24. He is expected to continue the rehabilitation program as part of his recovery, according to the press release.

"Rodriguez is the first double lung transplant the hospital has performed on a coronavirus patient since the pandemic began," Baylor St. Luke's Medical Center said in a statement. "To date, only a handful of transplant centers in the U.S. have performed lung transplants on patients due to irreversible lung damage caused by the virus."
