Bronchitis is divided into acute tracheobronchitis and chronic bronchitis. For patients with acute tracheobronchitis, the disease can usually be completely cured in 1-2 weeks because acute tracheobronchitis itself is a relatively mild respiratory infection, and patients recover better with effective treatment, and the prognosis is also very good. However, for patients with chronic bronchitis, because the disease itself is chronic in formation, the disease cannot be cured regardless of any form of treatment, and can only alleviate the clinical symptoms of the acute phase, and the clinical features of chronic bronchitis include coughing and coughing for 3 months each year, and the recovery time for patients with chronic bronchitis is longer compared to acute tracheobronchitis.
