Omicron subvariants that more easily dodge immunity are causing more than 70% of U.S. infections

(CNBC) The BQ.1 and BQ.1.1 Covid subvariants are now responsible for 68% of new cases, while the XBB subvariant is causing 4.7% of new infections. Covid infections and hospitalizations are rising after Thanksgiving, with Christmas and the New Year holidays still around the corner. These subvariants are resistant to key antibody treatments, and studies indicate they are better at evading antibodies from vaccination and infection.
