NFID Respiratory syncytial virus (RSV) is surging later than usual in parts of the country. Here’s which states have the highest rates and symptoms to watch for. Although cold and flu season is winding down in the United States, respiratory syncytial virus (RSV) activity still remains high in many parts of the country.
RSV is a highly contagious virus that can infect the lungs and airways. It’s very common, especially among children. While most healthy people who get RSV recover on their own, the infection can become severe or deadly.
In the U.S., RSV tends to ramp up in the fall and peak in the winter, usually in December or January, per the U.S. Centers for Disease Control and Prevention.
