Measuring temperature. Three year old boy suffering from fever holds a digital thermometer under his armpit to measure body temperature. His temperature is read in digital form in the window of the thermometer. Fever (pyrexia) is defined as a body temperature above 37 Celsius (98.6 Fahrenheit). Most fevers are caused by bacterial or viral infections and may be accompanied by other symptoms such as shivering, sweating, thirst and hot skin.
