Roseola is a generally mild infection that usually affects children by age 2. It occasionally affects adults. Roseola is so common that most children have been infected with roseola by the time they enter kindergarten.
Two common strains of herpes virus cause roseola. The condition typically causes several days of fever, followed by a rash.
Some children develop only a very mild case of roseola and never show any clear indication of illness, while others experience the full range of signs and symptoms.
Roseola typically isn't serious. Rarely, a very high fever can result in complications. Treatment of roseola includes bed rest, fluids and medications to reduce fever.
