December 21, 2021
NEW YORK - Omicron has raced ahead of other variants and is now the dominant version of the coronavirus in the U.S., accounting for 73% of new infections last week, federal health officials said Monday.
The Centers for Disease Control and Prevention numbers showed nearly a six-fold increase in omicron's share of infections in only one week.
In much of the country, it's even higher. Omicron is responsible for an estimated 90% or more of new infections in the New York area, the Southeast, the industrial Midwest and the Pacific Northwest. The national rate suggests that more than 650,000 omicron infections occurred in the U.S. last week.
