U.S. COVID cases surge ahead of holidays

New cases of the Omicron variant are spreading rapidly in the U.S. ahead of the holidays. People are dealing with long lines at testing sites across the nation. At-home testing kits are also short in supply and pharmacies are limiting how many customers can buy. CBS News correspondent Nancy Chen reports from New York City. Then critical care physician Dr. Lakshmana Swamy joins CBSN's Debra Alfarone to discuss the latest on the pandemic.

The FDA also authorized a new antiviral pill to treat COVID-19. CBS News' Nancy Chen reports on the latest, and then Dr. Amesh Adalja, an infectious disease expert at Johns Hopkins University Bloomberg School of Public Health, spoke with Jessi Mitchell on CBSN about the Omicron research and how some patients are experiencing different symptoms than earlier strains.
