In medicine, hyperpyrexia is an excessive and unusual elevation of set body temperature greater than or equal to 41.1° Celsius (106°F), or extremely high fever. Such a high temperature is considered a medical emergency. It differs from hyperthermia in that in hyperthermia the body temperature is too high above the set point, whereas in hyperpyrexia the body's temperature regulation mechanism sets the normal body temperature too high. It is very often fatal.
