is fifth disease slapped cheek?
Also called erythema infectiosum, it's caused by parvovirus B19. It's especially common in kids ages 5 to 15. Fifth disease causes a distinctive red rash on the face that makes a child appear to have a "slapped cheek." A few days later, the rash spreads down to the trunk, arms, and legs. It usually lasts 1 to 3 weeks.
