Full Answer

The fever associated with roseola often starts and stops suddenly, lasting between three and five days, says Mayo Clinic. The rash usually doesn't appear until after the fever breaks. The rash typically appears as several small dots or patches that are most often flat. Rash associated with roseola is not generally uncomfortable or itchy like rashes associated with other illnesses. Other potential symptoms include swollen eyelids, irritability, diarrhea, decreased appetite. Cold-like symptoms, such as runny nose, cough and sore throat may also be present, notes MedlinePlus.
