Recurrent fever in children may be caused by upper respiratory tract infection, pneumonia, tuberculosis and other diseases, and it is necessary to choose the appropriate treatment for the cause of the disease, such as medication, general treatment, as well as symptomatic treatment, including physical hypothermia, medication hypothermia and so on. 1. Upper respiratory tract infection: If children suffer from upper respiratory tract infection, they will have recurrent fever. If the upper respiratory tract infection is caused by viruses, it is self-limiting and generally does not require special medication, and should be rested and avoided. If it is caused by bacteria, you should follow the doctor’s instructions to take ceftazidime, amoxicillin and other antibiotic treatment. 2. Pneumonia: If the pneumonia causes the child to have recurrent fever, for Streptococcus pneumonia, amoxicillin clavulanate potassium treatment can be preferred; if it is caused by Mycoplasma pneumoniae, erythromycin, azithromycin and other macrolide antibiotics can be used. 3. Tuberculosis: Tuberculosis can also lead to recurrent fever in children, after diagnosis, you should follow the doctor’s instructions to take anti-tuberculosis drugs, such as isoniazid, rifampicin, ethambutol and so on. Because the disease is contagious, it should be isolated. During treatment, the child should be given plenty of fluids, and warm towels can be used to wipe the child’s skin to lower the temperature. If the child’s temperature exceeds 38.5°C, antipyretics such as ibuprofen and acetaminophen are needed. Children with recurrent fever, the family should take the child to the doctor in time for relevant examinations to clarify the diagnosis. The above drugs need to be used under the guidance of a doctor.
