It is also the most common pediatric emergency concern. Fever is defined as body temperature greater than 38°C (100.4°F). Fever is induced by exogenous pyrogens from invading organisms and by endogenous pyrogens that are released by immune mediating cells to fight infectious pathogens. The pyrogens cause the body’s central “thermostat” in the hypothalamus to reset.
