| pyrexia |
Fever, also known as pyrexia, is a medical symptom which describes an increase in internal body temperature to levels which are above normal (37 degrees Celsius, 98.6 degrees Fahrenheit). An adaptive mechanism, fever is the body's reaction to pathogens; it attempts to raise core body temperature to levels which will denature, debilitate, or kill the pathogen. Most fevers are caused by infections and almost all infectious diseases can cause fever. ...
