What are the early symptoms of pneumonia in children?

Children's pneumonia initially presents with obvious symptoms such as coughing and sputum production, accompanied by low-grade and high-grade fever. A small number of patients also have symptoms such as poor appetite and poor mental state.
1. Cough and sputum <br/>Pneumonia is initially accompanied by coughing, which is usually more severe than upper respiratory tract infection. The cough is louder and accompanied by obvious sputum. Pneumonia is caused by inflammation, which leads to increased secretions in the respiratory tract and shortness of breath.
2. Fever <br/>Most pneumonia patients have persistent fever. If the body temperature is found to be abnormal for more than 5 days after a respiratory tract infection, attention should be paid to whether pneumonia is present.
3. Poor appetite <br/>Some pneumonia patients may experience poor mental state or poor appetite, and have no interest in their favorite food.
