What Is Fifth Disease?

Fifth disease is a viral illness that most kids recover from quickly and without problems. It's especially common in kids ages 5 to 15.

Fifth disease is known for a rash that makes a child’s cheeks bright red. That’s why it’s sometimes called a "slapped cheek" rash. A few days later, the rash spreads down to the trunk, arms, and legs. It usually lasts 1 to 3 weeks.

What Are the Signs & Symptoms of Fifth Disease?

Fifth disease begins with:

  • a low fever 
  • headache
  • a stuffy or runny nose

These symptoms clear up, and the illness seems to be gone until the rash appears a few days later. Kids younger than 10 are most likely to get the rash.
