A fever signifies an abnormal, temporary rise in body temperature due to a medical condition. The rise can be continuous or may cycle over time. The onset of fever can occur due to a myriad of different medical conditions. Normally the human body has a temperature in the range of 37.5-38.3°C (99.5-100.9°F). If an illness occurs, body temperature rises above normal values and might go to extremes of 41-42°C (105.8-107.6°F).
