When the inflammation in the lungs cannot be completely eliminated, sputum smear tests must be performed promptly in a regular hospital to see if the patient is infected with Mycobacterium tuberculosis. Drug sensitivity test can selectively use antibiotics, because drug sensitivity test can determine which drugs are sensitive to pathogens, and targeted use of drugs can achieve rapid treatment of pneumonia. At the same time, it must be clear that the cause of the disease and other causes are viral or bacterial infections. Generally, if it is a bacterial infection, the patient is treated with relatively sensitive antibiotics, and the symptoms will be relieved. If it is a viral infection, antibiotic treatment is generally ineffective and requires treatment with hormones and antiviral drugs.
