A pandemic of the novel coronavirus has now infected more than 61 million people and killed over 1.4 million worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
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.

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."
Unfortunately, we know some will still get together and schools have asked for help. @VTEducation will direct schools to ask students or parents if they were part of multi-family gatherings and if the answer is yes, they'll need to go remote for 14 days or 7 days and a test. 9/

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.

With holiday travel approaching, a top White House coronavirus official warned against a false sense of security that a negative COVID-19 test might provide.
"Please remember that a negative test today does not mean you will be negative tomorrow or in a few days afterwards," Adm. Brett Giroir, assistant secretary of health at the Department of Health and Human Services, said on a call with reporters Tuesday. "We know that a single test can provide false senses of security. You still have to wear your mask and everything else."
"If you're negative today, you could be positive by Thanksgiving or Friday," he continued. "You can get it while you're traveling on vacation."
Giroir confirmed that the Trump administration is considering shortening the recommended coronavirus quarantine time from 14 days to 10 days, complemented by a negative test administered on day seven or 10 -- as first reported by The Wall Street Journal. They are "right now reviewing the evidence," he said.
Demand for testing ahead of the holiday continues to strain the diagnostics system, prompting recurrent warnings from major labs that turnaround times may be delayed. Testing could become even further strapped if a shortened quarantine would require a negative test.
When asked if the system has the ability to handle such widespread asymptomatic screening, Giroir said he was "certainly cognizant" of the turnaround times and was doing "everything possible to increase those supplies."
"Asymptomatic testing is very important, but we need to do that on targeted populations," he said. "We're not at the point that sort of every American can test themselves every day, without a reason to do that. We are trying to build that infrastructure."
