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. In children with acute bronchitis, if they cough and expectorate for more than 2 to 3 weeks, they can consider entering a chronic process. In recent years, many experts believe that it is more appropriate to make chronic cough with or without expectoration for more than 3 months.
