It primarily affects adults with underlying chronic obstructive pulmonary disease or long-term airway damage from noxious exposures such as tobacco smoke This clinical state is defined by a worsening of baseline respiratory symptoms, characteristically manifesting as increased dyspnea, heightened cough frequency, and elevated production of purulent sputum

Pathophysiologically, impaired mucociliary clearance permits bacterial adherence, mucosal invasion, and sustained neutrophilic airway inflammation
