Whether pneumonia without coughing is serious or not does not depend on the symptoms, but generally on the size of the pneumonia, whether the pathogenic microorganism causing the pneumonia is sensitive to the available medications, and whether the patient’s resistance is strong. If the area of pneumonia is not too large, and the pathogenic microorganism causing the pneumonia is sensitive, that is, sensitive to existing drugs, and the patient’s resistance is strong, the pneumonia will gradually resolve and be absorbed, and the pneumonia will not be serious. If the area of the pneumonia is large, or if the pathogenic microorganisms causing the pneumonia are resistant to the drugs, and if the patient’s resistance is not too good, the pneumonia in this case is more serious and may get progressively worse, or even life-threatening. Therefore, whether or not pneumonia without coughing is serious cannot be generalized, but depends on the size of the pneumonia area, whether the pathogenic microorganisms causing the pneumonia are drug-resistant, and the patient’s resistance.
