A fever is defined as a temperature 1° or more above the normal 98.6°. Minor infections may cause mild or short-term temperature elevations. Temperatures of 103° and above are considered high and can signal a potentially dangerous infection. Contact your doctor in case of a high fever or if a lower fever doesn't resolve with simple treatments.
