The omicron variant is accounting for the lion’s share of new coronavirus cases as Americans return to work and school following the holiday season, according to estimates from federal health officials.

Omicron made up 95% of all sequenced Covid-19 cases in the U.S. in the week ending Jan. 1, up from a revised 77% in the previous week, according to a model by the Centers for Disease Control and Prevention. Previously, the CDC estimated that the variant accounted for 58.6% of cases in the week ending Dec. 25.
