The shift reflects the spread of the omicron variant.
As the COVID-19 pandemic has swept the globe, more than 5.3 million people have died from the disease worldwide, including over 816,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
About 61.7% of the population in the United States is fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
Florida's COVID-19 positivity rate has soared to 13.8% this week, up from 5.3% the week prior, according to state data. One week before that, the positivity rate was just 2.6%.
Florida hit a record high of 31,758 daily cases on Thursday, surpassing the previous record set in August, according to ABC Miami affiliate WPLG.
This comes as the nation sees an increased demand for testing for the holidays.
When the University of Southern California's spring semester begins on Jan. 10, classes will be remote for the first week due to the spread of omicron, university officials said Friday.
In-person classes are set to start Jan. 18.
Students must show a negative test before attending in-person class, and all faculty, staff and students are required to get the booster shot, officials said.
Three of the seven boy banders in K-pop group BTS have tested positive for COVID-19, said their agency, Big Hit Music, according to The Associated Press.
One member, Jin, has a mild fever, while the other two to test positive, RM and Suga, are asymptomatic, the AP said, citing the agency.
Suga and RM tested positive while in quarantine in South Korea following trips to the U.S., the agency said, according to the AP.
The Centers for Disease Control and Prevention has issued an alert to health care professionals across the country to prepare for a possible major surge in infections of COVID-19 due to the high transmissibility of the omicron variant.
Among the CDC's contingency options is shortening the amount of time health care workers must self-isolate following a COVID-19 infection.
Under “conventional” conditions, health care facilities can allow asymptomatic personnel who were infected with COVID-19 to return to work after seven days and a negative test, regardless of vaccination status, according to the new CDC guidance. For health care personnel who were symptomatic, fever should have resolved without medications.
Under “crisis” conditions, health care workers can return to work after five days, if asymptomatic or mildly symptomatic, as a last resort, without testing, the alert states. These health care personnel should wear a respirator or well-fitting face mask, even when they are in non-patient care areas, and facilities should consider assigning them duties that do not include care of immunocompromised patients.
The plan was put into place to mitigate potential staff shortages, according to the CDC.
