Cough is a common clinical symptom that is commonly associated with a range of diseases such as bronchitis, lung infections, and respiratory system. The absence of a cough does not mean that one cannot have pneumonia, because patients with pneumonia can also have other manifestations of pneumonia such as fever and coughing, and the main cause of pneumonia is due to pathogenic infections. Therefore, it is understood that a cough is not necessarily pneumonia, and that patients with pneumonia do not always have a cough. However, as long as the diagnosis of pneumonia is confirmed, further treatment is needed. Broad-spectrum antibiotics can be chosen and symptomatic treatment can be made according to the patient’s other clinical symptoms, and antipyretic drugs can be used if necessary if the patient is febrile.
