Question: Does the magnitude of the temperature indicate the severity of the illness?


No, there is no pathognomonic degree of fever that has been clearly associated with a specific risk of infection in patients, although before the widespread use of the Haemophilus influenzae vaccine, temperatures greater than 41.1°C were associated with a higher incidence of serious bacterial illness. In pediatrics medical decision making, the temperature should be used as only one piece of information in conjunction with many other factors.
