Roseola epidemiology and demographics
Introduction
Overview
Overview
There is no accurate data for the prevalence or incidence of roseola. This is because the disease is a self limiting disease and it is under reported in most cases. Roseola is an illness of young children, with a peak prevalence between 7 and 13 months. Ninety percent of cases occur in children younger than two years. Roseola occurs equally in boys and girls. It occurs throughout the year, although outbreaks may occur in groups according to season .
