Cough is a rapid expulsion of air from the lungs typically in order to clear the lung airways of fluids, mucus, or material. Cough is also called tussis. Cough can be categorized as acute (less than three weeks) or chronic (greater than three weeks).
Chronic cough has many possible causes, including infectious and noninfectious conditions and diseases.
