President Joe Biden said he’s directing his team to procure 500 million additional tests to meet future demand -- bringing the total to 1 billion.

Biden said the White House is on track to roll out a website next week allowing Americans to order tests shipped to their homes.

The administration will also announce next week how it's making high-quality masks available for free, Biden said.

Biden also made a plea to social media companies and media outlets.

"Please deal with the misinformation and disinformation that’s on your shows -- it has to stop," he said. "COVID-19 is one of the most formidable enemies America has ever faced. We’ve got to work together."

The U.S. is now reporting an average of 1,650 new COVID-19-related deaths each day -- up by about 50% since Christmas, according to federal data.

Indiana currently has the highest death rate, followed by Delaware and New York City.

Twenty-six states are now averaging more daily cases than at any point in the pandemic, according to federal data.

Surging national case numbers, however, may not be indicative of what is happening in every region of the country. Some areas could see a decline or a plateau in cases, according to some experts.

President Joe Biden will deploy military medical teams to hospitals in six states where COVID-19 infections are surging.

Teams of doctors, nurses and clinical personnel will be sent as early as next week to New York, New Jersey, Ohio, Rhode Island, Michigan and New Mexico, Biden is expected to announce on Thursday alongside Secretary of Defense Lloyd Austin and FEMA Administrator Deanne Criswell.

Biden in December directed the defense secretary to ready 1,000 military medical personnel to deploy to hospitals across the country as needed in January and February. The teams now being readied will be the first to start arriving at hospitals.

They'll be sent to Cleveland Clinic in Ohio, Coney Island Hospital in Brooklyn, Rhode Island Hospital in Providence, Henry Ford Hospital near Detroit, University of New Mexico Hospital in Albuquerque and University Hospital in Newark, New Jersey.

Biden, Austin and Criswell on Thursday will also "be briefed on the administration’s efforts to send resources and personnel to hard-hit communities across the country that are experiencing a surge in hospitalizations due to the Omicron variant,” according to a White House official.

The labs shouldering much of the nation's PCR COVID-19 testing are getting slammed with demand again during omicron's surge, and now they're grappling with a new challenge: their workforces are getting hit by the virus they've been tasked with tracking.

The American Clinical Laboratory Association, the national trade association representing some of the leading clinical labs responsible for COVID diagnostics, is warning that their members' workforce is strained as more workers call out sick.

"Labs are now facing a wave of new issues brought on by a fast-spreading variant that has not spared the laboratory care work force," an ACLA spokesperson told ABC News.

COVID-19 infections have increased laboratory staff sick leave -- a "significant factor in determining overall capacity" at an industry-wide level, the spokesperson said.

"We have been pressured to get our capacity where we believe it can be because of the labor problems we see," Quest Diagnostics CEO Steve Rusckowski said Wednesday at the JPM Healthcare Conference. "Some of this is just getting the labor to do our work, but secondly, is because of callouts because of the virus have been considerable over the last two weeks."

British Prime Minister Boris Johnson apologized Wednesday for attending a party during England's strict lockdown in 2020.

It was the first time that Johnson acknowledged he went to a garden party at his official residence and office on London's Downing Street in May 2020. He is facing growing anger and calls for his resignation over claims he and his staff flouted COVID-19 restrictions by holding a "bring your own booze" party. At the time, Johnson's government had imposed restrictions barring people in England from meeting more than one individual outside their household.

During the weekly Prime Minister’s Questions session in the House of Commons in London on Wednesday, Johnson said he had considered the garden party to be a work event to thank his staff for their efforts during the pandemic.

"I want to apologize," Johnson told lawmakers. "With hindsight, I should have sent everyone back inside."

The prime minister urged people to await "the full conclusion" of an investigation by senior civil servant Sue Gray into several alleged parties by government staff. Gray will report her findings by the end of the month.

Opposition Labour Party leader Keir Starmer said Johnson's defense was "the pathetic spectacle of a man who has run out of road" and demanded he "do the decent thing and resign."

The prime minister declined to resign and didn't explicitly admit that he had broken any rules, but said he understood "the rage."

"I know that millions of people across this country have made extraordinary sacrifices over the past 18 months," he added. "I understand the anger, the rage that they feel at the thought that people in Downing Street were not following those rules."
