Children with respiratory tract infections mostly present with cough and runny nose, mostly viral infections, and do not need antibiotics. Oral administration of traditional Chinese medicine is sufficient. Children with fever, nasal congestion and runny nose can add acetaminophen, and small infants can add Ai Chang. Infants with upper respiratory infection can have high fever, and the acute period is mostly three days. If the fever persists, it should be taken seriously. When a child has a fever, loosen the clothes or wrap to dissipate the heat, or give a warm water bath to physically cool the body, the body temperature exceeds 38.5 ℃ can be given antipyretic drugs. Remember not to “cover”. If there is poor mental response, high fever that does not subside, refusal of breast milk or poor food intake, it should be given great attention and prompt medical consultation.
