Acute and Chronic Bronchitis

What is bronchitis?

Bronchitis is a condition in which the airways in the lungs, called bronchial tubes, become inflamed and cause coughing, often with mucus. Bronchitis can be acute (short-term) or chronic (long-term). Viral infections, such as the cold or flu, are usually the cause, and most people recover after a few days or weeks. Occasionally, acute bronchitis can be caused by a bacterial infection.
