Dr. James Antoon, an assistant professor of pediatrics at Vanderbilt University Medical Center, often goes an entire summer without diagnosing a single case of respiratory syncytial virus (RSV). The common illness, which typically results in mild, cold-like symptoms but can be severe in infants and elderly adults, usually goes along with the winter flu season.
But this summer, RSV cases are spiking, particularly in southern states. Around 2,000 confirmed cases were recorded across the U.S. during the week of July 10, 2021, compared to less than a dozen during the week of July 25, 2020.
