Tuberculosis generally has more typical disease features, and a clear diagnosis can be made by combining laboratory tests and imaging examinations. If abnormal shadows are found in the lungs, sputum examination will be performed to find Mycobacterium tuberculosis through microscopy. If Mycobacterium tuberculosis is found in sputum, the diagnosis of tuberculosis can be confirmed. If the sputum is negative for three consecutive times, it can be regarded as a cure of tuberculosis. The disease starts slowly and has a long course, with typical clinical manifestations, such as low fever or unstable body temperature, night sweats, wetting the blanket in severe cases, exhaustion, weakness and loss of appetite, etc. Cough is the most common symptom of tuberculosis, which can also be accompanied by coughing up sputum and blood in the sputum, or even blood clots or hemoptysis, and severe tuberculosis can lead to difficulty in breathing. Tuberculosis is a common disease in life, which can be clinically cured by regular treatment, but can recur and requires strengthening daily exercise to increase resistance.
