Spectrum News: Pamela Davis, the Arline H. and Curtis F. Garvin Research Professor at the School of Medicine, said the omicron variant is resulting in significantly less severe patient outcomes than the delta variant. She and a team of researchers compared the rates of severe outcomes among more than 14,000 people who contracted COVID-19 between Dec. 15 and Dec. 24 to outcomes from the fall period when the delta variant accounted for more than 99% of U.S. COVID-19 cases.
