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.
The United Kingdom recorded 91,743 cases over the last 24 hours, according to government numbers.
That brings the U.K.'s weekly total to 584,688 – a 60.8% increase from the previous week.
Government ministers are holding a cabinet meeting to discuss potential new measures to curb the spread.

Eighteen states have an ICU capacity of 15% or less. Michigan in particular has been struggling through its latest COVID-19 surge for nearly three months.
Henry Ford Hospital in Detroit is seeing an increased number of ventilators in use and the "overwhelming majority" of patients on ventilators are unvaccinated, Dr. Jayna Gardner-Gray told ABC News.
Sarah Rauner, a chief nurse practitioner at Beaumont Health, told ABC News, "I have seen and witnessed things in the last two years that have forever changed me."
"I remember thinking to myself when we were going through the third surge, 'What are we going to do if there's a fourth?' And here we are in the middle of a fourth surge in the holidays. I am very concerned," she said. "We are burnt out. We are tired and we are disheartened. So much of what we see on a daily basis is preventable. However, we are still living this every day."
Rauner has one ask of all Americans: "Get your family vaccinated."

The Israeli government on Monday passed a resolution adding the United States and Canada to its "red list," banning its citizens from traveling to those countries.
The ban, which would also stop visitors from those countries from entering Israel, is scheduled to go into effect Tuesday night at midnight local time, the prime minister's media advisor said in a statement following Monday's vote.
The Knesset Constitution, Justice and Law Committee has to approve the measure, which was recommended by the Health Ministry State Classification Committee.
Israeli citizens returning from "red list" countries must quarantine. Israelis are now barred from travelling to Belgium, Germany, Hungary, Italy, Morocco, Portugal, Switzerland and Turkey.
