RSV and Bronchiolitis in Babies

RSV is a common respiratory virus. In babies, RSV can sometimes cause bronchiolitis, which is inflammation of the small airways in the lungs.

Respiratory syncytial virus causes RSV infection. Other respiratory viruses can also cause bronchiolitis and similar symptoms such as cough, congestion, wheezing and faster breathing.
