Objective. To identify the percentage of parents who define the threshold for fever between 38.0°C and 38.3°C, which has not been reported previously, and to describe parental attitudes toward fever and antipyretic use. Study Design. Thirteen-question survey study of caregivers. Results. Overall, 81% of participants defined the threshold for fever as <38.0°C, 0% correctly defined fever between 38.0°C and 38.3°C, and 19% defined fever as >38.3°C. Twenty percent of children brought to clinic for a chief complaint of fever were never truly febrile. Ninety-three percent of participants believed that high fever can cause brain damage. For a comfortable-appearing child with fever, 89% of caregivers reported that they would give antipyretics and 86% would schedule a clinic visit. Conclusion. Our finding that 0% of parents correctly defined fever is both surprising and unsettling, and it should inform future discussions of fever between parents and clinicians.
