Tuberculosis and bronchitis are distinctly different.1 First, the causative agent of the infection is different. Tuberculosis is a clinical disease caused by Mycobacterium tuberculosis infecting the respiratory tract, and it is an infectious disease as well as a contagious disease. Bronchiectasis is an infectious disease caused by bacterial or viral infection of the airways. 2. Second, the clinical symptoms are different. Patients with tuberculosis usually have the toxic symptoms of tuberculosis, such as low fever in the afternoon, night sweats, lethargy, poor nutrition and weakness, which can be accompanied by different degrees of discomfort such as cough, hemoptysis, chest tightness and chest pain. Patients with bronchitis have milder clinical symptoms, with cough and sputum as their main manifestations and occasional low-grade fever.3 In addition, there are also differences in treatment. Patients with tuberculosis usually need early, combined, appropriate, regular and complete anti-tuberculosis drug treatment. Tracheitis, on the other hand, can be treated symptomatically and, if necessary, with anti-infective drugs.
