Types of Bronchitis
There are 2 kinds of bronchitis, acute and chronic, both with their own distinctive etiologies, therapies and pathologies. Acute bronchitis is characterized by the presence of cough, with or without sputum which is expectorated through the respiratory tract. Chronic bronchitis is an obstructive pulmonary illness characterized by the development of a productive cough lasting for 3 or more months in a year continuously for 2 years or more. It may develop as a result of recurrent damage to airways due to inhaled irritants.
