New York is experiencing its most severe week of flu activity on record since tracking began in 2004. The surge is not limited to New York; the CDC has labeled activity as “very high” in Colorado and Louisiana as well. Dr. William Schaffner, professor of medicine in infectious diseases at Vanderbilt University, joins to answer key questions: which groups are at highest risk for complications, the effectiveness of this year’s flu vaccine against circulating strains, the optimal window for antiviral treatment, and how to distinguish flu from COVID-19 or RSV variants.
