Here’s a look at today’s COVID-19 news.

CDC estimates 3 in 4 kids have had COVID

Three out of every four U.S. children have been infected with the coronavirus and more than half of all Americans had signs of previous infections, Centers for Disease Control and Prevention researchers estimated in a report Tuesday.

The researchers examined blood samples from more than 200,000 Americans and looked for virus-fighting antibodies made from infections, not vaccines. They found that signs of past infection rose dramatically between December and February, when the more contagious omicron variant surged through the U.S. Get more info here:

Vice President Kamala Harris tested positive for COVID-19 on Tuesday, the White House announced, underscoring the persistence of the highly contagious virus even as the U.S. eases restrictions in a bid to return to pre-pandemic normalcy.

What do we know about the new omicron mutant?

It’s a descendant of the earlier super-contagious “stealth omicron” and has quickly gained ground in the United States.

BA.2.12.1 was responsible for 29% of new COVID-19 infections nationally last week, according to data reported Tuesday by the U.S. Centers for Disease Control and Prevention. And it caused 58% of reported infections in the New York region.

The variant has been detected in at least 13 other countries, but the U.S. has the highest levels of it so far. Scientists say it spreads even faster than stealth omicron. Get more info here:

What is Title 42 and why is it sparking debate?

The Biden administration’s plans to lift Title 42 are raising concerns in border communities and sparking fierce debate in Washington.

Politicians have been sparring over whether it’s the right time to repeal the pandemic public health restrictions. And a federal judge’s decision may have just thrown a wrench in the government’s plans.

But what is actually happening? How is this different from the way things were handled in the past? And what could happen next? Read more here:
