Roseola Infantum
Diagnosis of Roseola Infantum
History and physical examination Roseola infantum may be suspected when a child aged 6 months to 3 years develops typical symptoms and signs. Testing is rarely needed, but diagnosis of roseola infantum can be confirmed by culture or serologic tests. Molecular assays (eg, quantitative polymerase chain reaction) are available but are more commonly used to detect viral reactivation.
