Is Bronchitis Contagious?
Bronchitis describes a group of symptoms (including airway inflammation, over-production of phlegm, and cough), which can have various causes. If the cause of the bronchitis is viral or bacterial, it can be contagious. If the cause of the bronchitis is due to smoking, air pollution, or other inhaled irritants, it is not contagious.
