Acute exacerbations of chronic bronchitis manifest as a change from baseline chronic symptoms. Symptoms include shortness of breath, increased production and/or purulence of sputum, increased sputum tenacity, and cough.

An estimated 80% of cases of acute exacerbations of chronic bronchitis are caused by infection, with about one half of those caused by aerobic bacteria, of which S pneumoniae is the most commonly isolated organism.

Symptoms such as sore throat, rhinorrhea, nasal congestion, and dyspnea may indicate a viral cause. [46]
