How many degrees of fever is considered high fever

A child with a fever of more than 39 degrees is considered high fever. Failure to actively treat it may cause the body temperature to continue to rise, leading to serious consequences such as febrile convulsions and meningitis. He should be admitted to the hospital and treated with antipyretic drugs as prescribed by the doctor. At the same time, he should also be combined with physical cooling to reduce the fever. The effect is better.
