Fever also referred to as pyrexia, is defined as having a temperature above the normal range due to an increase in the body’s temperature set point. There is not a single agreed-upon upper limit for normal temperature with sources using values between 37.2 and 38.3 °C (99.0 and 100.9 °F) in humans. The increase in set-point triggers increased muscle contractions and causes a feeling of cold or chills. It is one of the most common medical signs. It is part of about 30% of healthcare visits by children and occurs in up to 75% of adults who are seriously sick. While fever evolved as a defense mechanism, treating it does not appear to improve or worsen outcomes.
