Fever Overview

Man with a fever


Fever is a common sign and symptom observed in a variety of clinical settings.1

The normal body temperature is about 36.5°C to 38°C, with the typical temperature at 37°C. In a healthy afebrile person, the hypothalamic thermoregulatory centre of the brain regulates body temperature by balancing the heat produced during metabolism and that released through respiration and evaporation.1 However, when this balance is offset due to different reasons, fever sets in.
