Chronic bronchitis refers to repeated bronchial infections with a course of more than 2 years and an onset of more than 2 months each year.

Other diseases with such symptoms, such as tuberculosis, pulmonary abscess, heart disease, bronchiectasis, bronchial asthma, and chronic nasopharyngeal diseases should also be excluded.
