The course of pediatric pneumonia is usually 7-10 days, and some patients may continue to have a cough for up to 2 weeks after the pneumonia has resolved, but the exact duration of the cough depends on the patient’s condition. Pediatric pneumonia is usually due to pathogens and often presents with fever, a violent cough with or without sputum, and in some patients a sputum sound, especially in mycoplasma infections which are most likely to present with a violent dry cough. It is due to a protective reflex caused by pathogens or exudation stimulating the bronchi, and can last the whole course of the patient’s illness, even 2 weeks after the pneumonia is cured. Patients can take cough syrup or other cough medicines. If the cough is severe and wet rales are evident in the lungs, nebulization therapy can be used to accelerate the elimination of bronchial sputum. In addition, since pediatric pneumonia may cause some serious consequences, it is important for parents to pay attention to the condition and treat it promptly.
