I
or pyrexia
Abnormally high body temperature or a disease characterized by it.
It most often occurs with infection . Normal core body temperature, measured orally, does not exceed 99kF (37.2kC). Up to 105kF (40.6kC), fever causes weakness and is best treated with aspirin , acetaminophen , or other antipyretic drugs. At 108kF (42.2kC) or more, it can lead to convulsions and death. In treatment, it is important to know the underlying cause. Fever appears to be a defense against infectious disease, stimulating antibody production and perhaps killing or inhibiting bacteria and viruses that live within a narrow temperature range.
