PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - Fever is one of the most common causes for sick child visits to healthcare providers (HCPs). Fever, as distinct from hyperthermia, is defined as a regulated rise in core body temperature. Most clinicians define fever as an oral or rectal temperature of 38°C (100.4°F) or higher. In the pediatric age group, infection due to a virus (most likely) or bacteria (eg, urinary tract infection) is the most common cause of fever, and the HCP must always be alert to serious etiologies. The tendency to seek medical attention for fever is very much age-dependent, with younger children brought to care most often. Although part of the tendency to seek medical attention for fever rests with parental anxiety, part rests appropriately with the increased risk of serious infection associated with fever in the youngest children (especially neonates), as well as in special high-risk groups.
