A 2-year-old male is brought to the emergency department by his father who is concerned as the child has developed a rash. The father tells you the rash started yesterday evening but only affected the face and behind the ears. Dad thought the child had a cold as he has had a dry cough, itchy eyes, and runny nose for the past 2-3 days but became concerned when the rash and high fever appeared. On examination, you note the child has a widespread rash to the trunk, limbs, and face which is maculopapular in some areas while the erythema is more confluent in other areas. There are small blue-white spots seen to the buccal mucosa. The child’s temperature is 39ºC. You note the child has not received any childhood vaccines.
What is the likely diagnosis?
