(StatePoint) Each year, as many as 80,000 children younger than 5 are hospitalized due to respiratory syncytial virus (RSV) in the United States. RSV is the leading cause of hospitalization in all infants. New medical advancements however are safeguarding infants and some toddlers at increased risk, and providing hope.

As RSV season ramps up, the American Lung Association is partnering with Sanofi to help educate parents and expectant parents about the symptoms of RSV and the steps they can take to help prevent severe illness. Here is what they want you to know: Risk factors: Virtually every child will contract RSV at some point, however those at highest risk for severe illness and complications are: • Premature newborns • Babies up to 12 months old, especially if they are 6 months old or younger • Children younger than 2 who have a chronic lung disease or heart disease that was present at birth • Children who have weakened immune systems • Children who have neuromuscular disorders New protection: In 2023, two preventive immunization options were recommended by the Centers for Disease Control and Prevention to help protect infants from serious RSV illness: a preventive RSV antibody for infants and some young children at increased risk, and an RSV vaccine received during weeks 32-36 of pregnancy. The RSV antibody is recommended from October through March and provides protection for at least five months after immunization.

The RSV vaccine is recommended from September.
