Etymology: Roseola is a diminutive of the Latin "rosa," meaning "rose," with the suffix "-ola" giving the sense of "a little" or "a small kind of" something. The name was built in New Latin, the scholarly Latin used by physicians and naturalists, to describe a faint pinkish rash. The rash is the reason for the choice: the spots look like small roses on the skin. The condition the word names is a common childhood illness, usually caused by human herpesvirus 6 or 7, that brings a high fever for several days. The rash tends to appear only once the fever breaks, which is why the name points to the appearance of the skin rather than to the fever itself.
