FEVER
Fever remains the most common concern prompting parents to present their child to the emergency department. Fever has traditionally been defined as a rectal temperature over 100.4 F or 38 C. Temperatures measured at other body sites are usually lower. The threshold for defining a fever does vary significantly among different individuals since body temperatures can vary by as much as 1 F. Low-grade fevers are usually considered less than 102.2 F (39 C).
