When to Call A Doctor

Call your doctor if you or your child develops a facial rash, especially if your child has a blood disorder or an immune deficiency, or is being treated for cancer. Also, call your doctor if a child with previously diagnosed fifth disease develops a fever or increased joint pain.

Pregnant women who believe they have been exposed to fifth disease or who develop a rash should call their doctors immediately. Although fifth disease in the mother usually does not threaten the unborn child, fifth disease in rare cases can cause miscarriage or fetal anemia.
