Erythema infectiosum

Erythema infectiosum is self-limited and resolves without sequelae in the majority of cases. Parents of children should be advised that the generalised exanthem may persist for several weeks and may intensify with increased body temperature (bathing, exertion), but this does not represent recrudescence of the disease. In the immunosuppressed population, persistent B19 infection with resultant anaemia may occur.
