Exanthem subitum; Sixth disease
Definition of Roseola
Roseola is an acute disease of infants and young children in which a high fever and skin rash occur.
Causes, incidence, and risk factors
The disease is common in children ages 3 months to 4 years, and most common in those ages 6 months to 1 year. It is caused by a virus called human herpesvirus 6 (HHV-6), although similar syndromes are possible with other viruses.
The child may have a runny nose, sore throat, and eye redness.
There is no specific treatment. The disease usually gets better without complications.
Most children with roseola fully recover.
