Coronavirus deaths in the United States have surpassed 450,000. The number of daily deaths remains stubbornly high at more than 3,000 a day, despite falling infections and the arrival of multiple vaccines. Infectious disease specialists expect deaths to start dropping soon, after new cases hit a peak right around the beginning of the year. The new director of the Centers for Disease Control and Prevention says new COVID-19 deaths could ebb as early as next week. But there’s also the risk that improving trends in infections and hospitalizations could be offset by people relaxing and coming together — including this Sunday to watch the Super Bowl.
