A fever is a body temperature of 100.4° Fahrenheit of higher. When you have multiple fevers over a period of time, this could be a recurring fever. These fevers that come and go are usually seen in children under age 5 (infants and toddlers).
A fever is a part of your body’s natural defense system. Your immune system is the part of your body that works to fight off illnesses. When this system is triggered,
your body’s temperature heats up. Typically, your average body temperature should be around 98.6° Fahrenheit (or 37° Celsius). A fever is a temperature of 100.4° Fahrenheit or higher.
If you take a child’s temperature orally or axillary (armpit), you might get a reading that’s up to one degree off. To get the most accurate temperature reading, take the child’s temperature rectally.
