Children with recurrent fever of 39 degrees Celsius need antipyretic medication (e.g., ibuprofen, etc.), which can be combined with physical antipyretic treatment (e.g., warm water rubbing of the body, etc.) to prevent children from experiencing febrile convulsions. The child may lose body fluids due to fever, so the child should drink plenty of fluids or go to the hospital for rehydration therapy. 2. Although the child’s throat is not sore or red, it may be infected by bacteria in other parts of the body, e.g., urinary tract infection, and the child needs antibiotics to fight infection (e.g., cefotaxime, etc.) in addition to antipyretic treatment. 3. Immunologic diseases (e.g., lupus erythematosus) may also cause recurrent fever and may require immunosuppressive (e.g., cyclophosphamide) or hormonal (e.g., methylprednisolone) therapy. It is recommended that the child go to the hospital in time to complete the relevant examinations to clarify the cause of the disease and then carry out targeted treatment, and the above drugs should be used under the guidance of a doctor.
