Rampant Omicron becomes U.S.’s dominant strain: 377,014 Americans are diagnosed with COVID in 24 HOURS – one day after a record 512,553 caught the virus

The chart showed that the Omicron variant accounted for 59 percent of all new cases for the week ending on December 25, meaning the Delta variant has been accounting for far more infections than the agency initially thought, though Omicron is gaining ground quickly. ‘There’s no way around it, it is a huge swing that makes it seem like something went really wrong,’ Dr. Shruti Gohil, the associate medical director for epidemiology and infection prevention at UC Irvine’s School of Medicine, told NPR.
