A former FDA commissioner is predicting the next few weeks "are going to be very tough" as the coronavirus continues to spread across the U.S. "We're going to see more new cases. We're going to see spread to new areas. And we're going to see hospitals and health care providers struggling to keep up with the number of patients suffering from this disease," Dr. Peggy Hamburg, former FDA commissioner and former health commissioner for New York City, told Cheddar Friday.
