If Mycobacterium tuberculosis is isolated inside the sputum it must be tuberculosis, because finding antacid bacilli in the sputum is the gold standard for diagnosing tuberculosis. Tuberculosis is an acute respiratory infectious disease, mainly due to infection with Mycobacterium tuberculosis and a series of symptoms in the lungs. It is mainly transmitted by droplets, and the clinical symptoms are typical, including low afternoon fever, night sweats, fatigue, loss of appetite, depression, cough, sputum, blood in the sputum, and some women of childbearing age may also experience menstrual irregularities. Once diagnosed, it is recommended to go to the local designated infectious disease hospital for standardized anti-tuberculosis treatment, which should be sufficient in duration and dosage.
