Acute bronchitis (chest infection)

Acute bronchitis is the most common type of chest infection.

Bronchitis is an infection in the large airways in your lungs, called bronchi. Acute means it comes on quickly and doesn't last long. In acute bronchitis your bronchi are infected and become inflamed and irritated, causing a cough and sometimes sputum (phlegm).

It is different from chronic (long-lasting) bronchitis, which may be part of chronic obstructive pulmonary disease (COPD).
