What is Roseola Infantum (Sixth Disease)?

Roseola infantum, also known as the sixth disease, is an exanthem disease caused by human herpesvirus 6 (HHV-6) and HHV-7. It affects infants between 6-24 months.

The clinical course is quite typical: during 3-5 days of high fever (39-40°C), the child usually appears restless only due to fever without general deterioration. Immediately after the fever drops, a pink maculopapular rash starts on the trunk and spreads to extremities.

The rash fades quickly without leaving any mark. Febrile convulsion risk may increase during high fever. Treatment is symptomatic and prognosis is excellent.
