The following treatment measures can be used for babies with recurrent fever: 1. If the child’s fever is within one day, the child’s mental state is good, he can eat and drink and play as usual, and there is no other special discomfort, antipyretic drugs such as acetaminophen can be given symptomatically; 2. If the child has a fever of more than 2-3 days, and repeatedly take medicine, still can not be controlled, it is recommended to promptly go to the hospital for examination to clarify the cause of the fever, only to find the cause, in order to treat the symptoms, otherwise antipyretic drugs can only relieve the symptoms of early fever. Fever is a self-protective mechanism of the body and it can be a concomitant symptom of many diseases. The most common cause is infection, about 50%-80% of children have fever due to infection, in addition, 20% of children have fever due to other non-infectious factors, such as connective tissue disease, tumors, etc., but it is less common.
