Chicago Public Schools has been in talks with teachers over COVID-19 safety.
As the COVID-19 pandemic has swept the globe, more than 5.4 million people have died from the disease worldwide, including over 837,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
About 62.5% of the population in the United States is fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
Sweden's King Carl XVI Gustaf and Queen Silvia tested positive for COVID-19 last night, according to a palace statement.
Both are fully vaccinated and have received a third booster shot.
The king and queen said they have mild symptoms and are feeling well, in the statement.
They are isolating at home and contact tracing is ongoing.
More than 1 million new COVID-19 cases were reported in the United States on Monday, according to Johns Hopkins University.
The 1,082,549 new infections were about double last week's record daily cases, according to the university's data. This is likely due to a reporting backlog of cases from holiday testing.
The US recorded 1,688 deaths related to COVID-19 on Monday, below the record high of 4,442, set on Jan. 20, 2021, according to the university's data.
A record 325,000 children tested positive for COVID-19 last week amid the nation's most significant COVID-19 infection surge yet, according to the American Academy of Pediatrics and the Children’s Hospital Association.
Children accounted for about 17.4% of last week's reported COVID-19 cases, down from previous weeks, when children accounted for more than a quarter of all new cases.
A total of nearly 7.9 million children have tested positive for the virus, since the onset of the pandemic.

New York's hospitals will be required to report a breakdown of how many COVID-19 patients were admitted due to the coronavirus and how many were admitted for other needs and only discovered they were infected during their stays.
During a COVID-19 briefing on Monday, Gov. Kathy Hochul cited anecdotal reports of as many as 50% of patients at some hospitals testing positive for the virus who were actually admitted for other reasons, such as car accidents.
"I just want to always be honest with New Yorkers about how bad this is," Hochul said. "Yes, the sheer number of people infected are high, but I want to see whether or not the hospitalizations correlate with that."
She continued, "And I'm anticipating to see that at least a certain percentage overall are not being treated for COVID."
Hospitals will begin reporting their breakdowns Tuesday, but it's unclear how soon the data will be publicly available.
