Pneumonia is a common infectious disease of the respiratory system. Its main diagnostic methods include routine blood tests, C-reactive protein, and pulmonary imaging, among which pulmonary imaging is the gold standard for diagnosing pneumonia. Diagnosis can also be initially inferred from the patient's clinical presentation and medical history to determine the likelihood of a pneumonia infection. Once pneumonia is confirmed, there is no need for excessive worry. Active medication to control the infection can cure pneumonia. Therefore, anti-inflammatory treatment should continue once pneumonia is diagnosed.
