What parents need to know about RSV
Respiratory Syncytial Virus (RSV) is a highly contagious virus that can lead to respiratory infection in babies, including serious lung infections. However, most of the time RSV will cause a mild, cold-like illness. RSV spreads when droplets from a cough, sneeze, or infected surface get inside the eyes, nose, or mouth.
The typical RSV season usually occurs from fall through spring, but can vary by local area.
2 out of 3 babies will get RSV by age 1.
RSV can go from cold-like symptoms to hospitalization in less than a week.
Babies are 16x more likely to be hospitalized with RSV lung infection than with the flu.
Although severe RSV is rare, RSV is the leading cause of hospitalization in babies under age 1.
On average, babies hospitalized with RSV stay for 3-4 days in hospital.
