It causes a high fever, which is often followed by a rash on the trunk torso that may spread to the face, arms and legs. The rash is typically characterized by small, painless pink or red spots that turn white when pressed firmly. The spots may be flat or raised and may be surrounded by a white ring. The rash can fade quickly, within a few hours of appearing, or remain for a couple of days.
