What is bronchiolitis?
Bronchiolitis (say: "bronk-ee-oh-lie-tus") is a lung infection that can be caused by several kinds of viruses. Young children, particularly those between 3 months and 6 months old, get this illness in the winter and the early spring. Most children are sick for about a week to 10 days and then get well.
