The Winter of discontent approaches.
NEW YORK (AP) — 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.
CDC’s estimates are based on thousands of coronavirus specimens collected each week through university and commercial laboratories and state and local health departments. Scientists analyze their genetic sequences to determine which versions of the COVID-19 viruses are most abundant.
On Monday, the CDC revised its estimate for omicron cases for the week that ended Dec. 11, after analyzing more samples. About 13% of the cases that week were from omicron, not the 3% previously reported. The week before, omicron accounted for just 0.4% of cases.
CDC officials said they do not yet have estimates of how many hospitalizations or deaths are due to omicron.
Though there remain a lot of new infections caused by the delta variant, “I anticipate that over time that delta will be crowded out by omicron,” Walensky said.
