Disease analysis: cough, sputum for more than two weeks or blood in sputum are common suspicious symptoms of pulmonary tuberculosis. When the cough is mild, dry cough or a small amount of mucus sputum, cavities form, and the amount of sputum increases. If associated with other bacterial infections, the sputum may be purulent. If bronchial tuberculosis is present, it presents with an irritating cough, with minimal hemoptysis in most patients and massive hemoptysis in a few cases. Patients with pulmonary tuberculosis are more likely to have blood-streaked sputum in their sputum. Tuberculosis is contagious and should be isolated and its utensils and excreta should be cleaned and disinfected.
