COVID-19 updates: Elizabeth Warren tests positive
The senator says she's experiencing "mild symptoms."
As the COVID-19 pandemic has swept the globe, more than 5.3 million people have died from the disease worldwide, including over 806,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
About 61.4% of the population in the United States is fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

CDC studies find schools can test kids rather than quarantine
The Centers for Disease Control and Prevention on Friday endorsed a practice in schools called “test-to-stay,” which allows unvaccinated kids and staff to test instead of quarantine after being exposed to COVID-19.
The CDC says the practice can be employed in addition to other mitigation measures, such as vaccination and at least 3-feet of physical distance among students wearing masks.
The new guidance follows two studies out of Los Angeles County, California, and Lake County, Illinois. Both studies found no significant transmission in school when test-to-stay was used.
The studies were conducted before the omicron variant was detected in the U.S.

Hospitals stretched thin in Wisconsin, Michigan
In Wisconsin, only 4% of ICU beds are available.
"This is getting really scary," Dr. Jamie Hess, an emergency physician at the University of Wisconsin, told ABC News.
"We're really reaching a crisis point where we have more patients to take care of then we have beds in the hospital or staff to care for them," Hess said.
Michigan has been struggling through a similar surge for nearly three months, with the state reporting more than 6,500 new cases each day. On average, more than 500 patients are being admitted to hospitals each day.
"Where we are right now feels a lot like the first surge back in March of 2020," Erin Dicks, a nurse manager at MICU Henry Ford Hospital, told ABC News. "We don't have enough beds to be able to manage this."
Dicks said so many patients are young.
"I think one of the biggest frustrating pieces for my staff is that they look at this as, this is preventable -- people don't have to die here," Dicks said.

CDC committee recommends opting for Pfizer or Moderna over J&J if given choice
The CDC's advisory committee recommended Thursday that people who have a choice should get an mRNA vaccine, either Pfizer or Moderna, over the single-shot Johnson & Johnson vaccine after a review of new CDC data on rare blood clots linked to J&J.
The vote was unanimous.
The rare blood clots are not a new safety concern and the vaccine has already become far less common in the U.S. after it was given an FDA warning label about the clotting condition. But more data that confirmed a slightly higher rate of clotting cases and deaths than was previously reported caused the CDC and FDA to take another look at the data this week.
The CDC has confirmed nine deaths and 54 cases from the severe clotting event, thrombosis with thrombocytopenia.
There could also be more cases and deaths because TSS is under-diagnosed and could be underreported, the CDC said.
The clotting is more common among women in their 30s and 40s but has been seen in adult men and women of all ages.
The experts said J&J should not be taken off the shelves and is still far more beneficial than not getting any vaccine at all.
