Acute bronchitis - Overview

Alternative Names

Bronchitis - acute

Definition of Acute bronchitis:

Acute bronchitis is an inflammation of the main airways to the lungs (the bronchi) that usually lasts for a brief period of time.

It is not the same as chronic bronchitis, which often persists for a longer period of time.

Causes, incidence, and risk factors:

Acute bronchitis is one of the most common medical conditions seen in a doctor's office. It is mainly caused by a virus that infects the respiratory system. There are many different respiratory viruses that can do this, including the rhinovirus, which causes the common cold.

You have a higher risk for getting bronchitis if you've had a recent illness or viral respiratory infection (which reduce your ability to fight off infections), or if you have chronic lung problems such as asthma, cystic fibrosis, or chronic obstructive pulmonary disease. You are also at higher risk for bronchitis if you smoke.
