Bronchitis and tuberculosis are two different respiratory diseases, and bronchitis is divided into acute bronchitis and chronic bronchitis. Acute bronchitis is caused by bacterial or viral infections, while chronic bronchitis is mainly caused by smoking, atmospheric pollution, dust exposure, etc. Patients with bronchitis need to be treated with anti-infective and symptomatic treatments to stop coughing and expectorant phlegm. Tuberculosis is a common chronic infectious disease of the respiratory system, which is often infectious and can also occur secondary to bronchitis, due to the onset of infection with Mycobacterium tuberculosis.
