What it means

Also called roseola infantum or sixth disease, it mostly affects children 6 months to 2 years old. A high fever lasts 3 to 5 days, and as the fever breaks, a pink, flat or slightly raised rash appears on the trunk and spreads. The child usually feels better once the rash appears. The sudden high fever can trigger febrile seizures.

For the nurse

Teach the family to manage fever with fluids and acetaminophen or ibuprofen as directed, what to do during a febrile seizure, and to seek care if the child is very sleepy or not drinking.
