(CNN) -- COVID-19 case numbers have begun to edge up in the United States, and nearly all of them are caused by the Omicron subvariant BA.2. According to the latest estimates from the CDC, BA.2 caused 86% of new COVID-19 cases nationwide last week.
COVID-19 cases are rising again in the Northeast, due in part to the omicron's highly contagious BA.2 subvariant — but the White House's new Covid czar isn't too worried about it just yet.
The uptick in new U.S. coronavirus cases in recent days is concerning, Anthony S. Fauci, MD, said Sunday. But he suggested that the rise was not yet cause for alarm and that officials were monitoring it "very, very carefully."
WASHINGTON, April 7 (Reuters) - A U.S. appeals court panel on Thursday reinstated President Joe Biden's executive order mandating that federal civilian employees be vaccinated against COVID-19.
