Fever should not necessarily be treated.[56] Most people recover without specific medical attention.[57] Although it is unpleasant, fever rarely rises to a dangerous level even if untreated. Damage to the brain generally does not occur until temperatures reach 42 °C (107.6 °F), and it is rare for an untreated fever to exceed 40.6 °C (105 °F).[56] Treating fever in people with sepsis does not affect outcomes.[58]
