What is Slapped Cheek Syndrome?

Slapped cheek syndrome (fifth disease) is a common, usually mild viral illness in children, caused by parvovirus B19. It gets its name from the bright red rash that typically appears on the cheeks, sometimes followed by a lacier, pink rash on the body and limbs a few days later.

Most children feel only mildly unwell, with symptoms like a low fever or tiredness before the rash appears. By the time the rash shows up, children are generally no longer contagious, so exclusion from school isn't usually necessary at that stage.
