Myths and Facts about Fevers
Myth: All fevers are bad for children.
Fact: Fevers are one of the body's protective mechanisms. They turn on the body's immune system and help the body fight infection.
Myth: Fevers cause brain damage, or fevers >104°F are dangerous.
Fact: Fevers with infections don't cause brain damage. Only body temperatures >108°F can cause brain damage. Fevers only go this high with high environmental temperatures (for example, being confined in a closed car on a hot day).
Myth: Anyone can have a febrile seizure.
Fact: Only 4% of children can have a febrile seizure.
Myth: Febrile seizures are harmful.
