The need for infusion when influenza fever is present is recommended to be decided according to the patient’s clinical manifestations and related tests. The principle of medication is not to use medication as much as possible, and to choose oral medication as much as possible, if oral medication does not relieve the symptoms, infusion can be chosen to improve the symptoms. If the body temperature exceeds 38.5℃, antipyretic drugs can be given orally, and physical cooling can be combined with drinking more water and repeatedly rubbing the body with warm water. If the body temperature cannot be controlled within the normal range by both medication and physical cooling, or if other complications arise, you need to go to the hospital immediately so that the doctor can choose the appropriate infusion treatment according to the situation.
