Respiratory Syncytial Virus (RSV)

Bronchiolitis is almost always caused by a viral infection. In most cases, the respiratory syncytial virus (RSV) is responsible.

RSV is a very common virus and almost all children are infected with it by the time they’re 2 years old.

In older children and adults, RSV may cause a cough or cold, but in young children it can cause bronchiolitis.
