Fever occurs 15%-30% of the time, along with
nasal congestion and drainage, sore throat
, fatigue, muscle aches, and a headache. This lasts for several days.
Then, seven to 10 days later, the characteristic facial rash (the "slapped cheeks" appearance) develops abruptly. Typically, the facial rash is bright red. The child looks as if a hand has been slapped across his or her face. This rash fades in around four days.
