Chronic bronchitis is not necessarily caused by infection and is generally part of a syndrome called chronic obstructive pulmonary disease (COPD); it is defined clinically as a persistent cough that produces sputum (phlegm) and mucus, for at least three months in two consecutive years. In late stages, the disease may present with blue discoloration of body (cyanosis) and difficulty in breathing (dyspnea).
