Fever in Children Overview
Fever remains the most common concern for which parents bring their child to the emergency department. Fever has traditionally been defined as a rectal temperature over 100.4°F or 38.0°C. Temperatures measured at other sites are usually lower. The threshold for defining a fever does vary significantly between different individuals by as much as 1°F.
Fever itself is not life-threatening unless it is extremely and persistently high, such as greater than 107°F (41.6°C) when measured rectally. Fever may indicate the presence of a serious illness, but usually a fever is caused by common infections which are not serious. The part of the brain called the hypothalamus controls body temperature. The hypothalamus increases the body's temperature as a way to fight the infection. However, many conditions other than infections may cause a fever.
