Two very similar sounding illnesses are not exactly the same. Bronchitis and bronchiolitis both affect the airways that lead to the lungs, but bronchitis is more common in older children and adults while bronchiolitis primarily affects young children.
Acute bronchitis is an infection that attacks the bronchial tubes which lead to the lungs. It most commonly follows another upper respiratory infection such as a cold or the flu.
Bronchiolitis affects mainly young children and can have a variety of different causes - most of them viruses. It is one of the most common causes of wheezing in children.
These two illnesses are similar but aren't exactly the same. Be sure you know the differences between bronchitis and bronchiolitis before they affect you or your loved ones.
