Signs and symptoms may include fever, nausea, vomiting, and diarrhea, along with typical viral symptoms of sensitivity to light, enlarged lymph nodes, sore throat, and possibly brain inflammation. The rash may appear at any time during the illness. It is usually generalised. The rash consists of erythematous maculopapules with areas of confluence. They may be urticarial, vesicular, or sometimes petechial. The palms and soles may be involved. The eruptions are more common in children than in adults. Usually, the rash fades without pigmentation or scaling.
