Fever or pyrexia is not an illness, but a symptom which is characterized by an elevation in body temperature. Fever is a consequence of an underlying condition such as infection. Hypothalamus is the center of the brain which maintains the body temperature to a set point. The normal body temperature varies from 36-37.5°C (97o F to 99o F). When there is an infection, the hypothalamus resets the body to a higher temperature.
