Respiratory syncytial virus (RSV) is a common respiratory virus that can cause severe breathing complications in babies, especially those younger than 6 months old. While many adults recover quickly from RSV with mild symptoms similar to a cold, infants often face a much greater risk of hospitalization due to their developing immune systems and smaller airways. One hundred to 300 children aged less than 5 years die of RSV each year.
