After plummeting for several weeks, the number of new COVID cases in the U.S. has largely leveled off.

Driving the news: The CDC confirmed this week the Omicron subvariant BA.2, which has been driving surges of COVID elsewhere around the world, has become the dominant strain circulating in the U.S.

By the numbers: The U.S. is now averaging roughly 29,253 new COVID cases per day, a 6% drop from the rolling average of about 31,000 cases two weeks ago (and about even with new cases just a week ago).
