Pale pink papules on the trunk of a child.
Roseola, also known as exanthem subitum

Roseola, also known as exanthem subitum, is a viral infection caused human herpes virus 6 and 7.


The patient, typically 1-2 years of age, develops a high fever, but does not act sick. S/he may run around playing--seemingly full of energy. As the fever breaks, multiple, small, evanescent 1-3 mm pink papules develop. Rarely, seizures may occur because of the high fever.


No treatment is needed. Supportive measures such as bed rest, fluids and medications to reduce fever may be recommended.
