About 1 in 15 people in England tested positive for COVID-19 in the week ending Dec. 31, 2021, according to new data published Wednesday by the UK's Office of National Statistics -- a jump from 1 in 25 the week before.

This means that an estimated 3,270,800 people in the country caught the virus last week, with the most infections occurring among those between ages 17 and 24, the ONS said.

Additionally, 1 in 20 people contracted COVID last week in Scotland and Wales as did 1 in 25 people in Northern Ireland.

The ONS noted that these estimates do not include people who tested positive in "hospitals, care homes and/or other communal establishments."

COVID-19-related hospitalizations in New York surpassed 10,000 for the first time since the early days of the pandemic.

As of Tuesday, there are 10,411 people hospitalized statewide with the virus, which is the highest figure seen since May 2020.

About 1,300 patients are currently in intensive care units.

Unvaccinated New Yorkers are more likely to be hospitalized than those who are fully vaccinated. During the week ending Dec. 20, unvaccinated people were hospitalized at a rate of 30.01 per 100,000 compared to a rate of 2.08 per 100,000 for fully vaccinated people, according to state data.

Polish President Andrzej Duda tested positive for COVID-19 Wednesday.

This is the second time Duda has contracted the virus. He previously tested positive in October 2020.

"The president is fine, has no severe symptoms and is under constant medical care," Pawel Szrot, Head of the Cabinet, tweeted Wednesday.

Szrot said Duda is fully vaccinated and received a booster shot last month.

Michigan Gov. Gretchen Whitmer was isolating after her husband, Dr. Marc Mallory, tested positive for COVID-19, her office said in a statement.

Whitmer's office said the governor tested negative on Tuesday using a rapid test. She was awaiting the results of a PCR test.

"Thankfully, the entire family is fully vaccinated and boosted, so the governor has not tested positive and is not experiencing symptoms," Whitmer's office said in a statement. "Until the PCR test comes back, the governor is isolating in a separate area of the house and has taken steps to complete contact tracing to keep others safe."

The American Medical Association, the nation’s largest association of physicians, has criticized the Centers for Disease Control and Prevention's new quarantine and isolation guidance for COVID-19, saying the recommendations "are risking further spread of the virus."

The CDC updated its guidelines on Dec. 27, saying asymptomatic people who test positive for COVID-19 should self-isolate for five days rather than 10.

"The American people should be able to count on the Centers for Disease Control and Prevention (CDC) for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities. Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus," the American Medical Association's president, Dr. Gerald E. Harmon, said in a statement Wednesday night.

Harmon referenced data cited by the CDC in its rationale for shortening the isolation period, which estimates 31% of people remain infectious five days after a positive COVID-19 test, suggesting that data proves thousands of Americans could return to their lives while still infected.

"With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands -- potentially hundreds of thousands of people -- could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after five days without a negative test," Harmon said. "Physicians are concerned that these recommendations put our patients at risk and could further overwhelm our health care system."

Harmon said a negative COVID-19 test should be required for ending isolation after a positive test, as reentering society without knowing whether an individual is still positive ultimately risks further transmission of the virus.

Although test availability remains an issue nationwide, Harmon also called on the Biden administration to ramp up production and distribution of tests, adding that "a dearth of tests at the moment does not justify omitting a testing requirement to exit a now shortened isolation."
