Fever is the most common symptom in children, and can be caused by viral or bacterial infections, or even by non-infectious diseases. Parents should not be too anxious when a child starts to have a fever, as this means that the child is actively fighting against the “disease invasion”, and fever in children is most often caused by viruses, which do not require antibiotics, as viral infections are self-limiting and will resolve on their own for 3-5 days, up to 1 week. If the fever is accompanied by a significant decrease in mental status and appetite, blood tests and C-reactive protein should be done to find out if there is a bacterial infection, and if so, antibiotics should be administered. If the child has a fever, actively reduce the fever with oral antipyretics, physical cooling (ice packs, baths), and drinking plenty of fluids until the acute phase of the fever has passed. If there is no improvement in temperature for 3 days (maximum daily temperature decreases and the number of fevers decreases), and there is a decrease in overall mental status and appetite, medical attention is needed. Parents’ misconceptions: Children with fever can burn themselves silly, become pneumonia, burn into something or other. Fever is a result of disease, not the cause of disease, except for febrile convulsions, which are caused by high body temperature. A fever will not make a child stupid, unless the child has an encephalitis or other disease that may cause intelligence, because children with encephalitis also have fever. If you have uncontrollable recurrent fever, please come to the hospital and let the doctor help you diagnose the disease, do not delay at home, and do not be too anxious.
