What are the complications of fifth disease?
In most cases, there are no complications and children and adults recover completely. There is more of a risk of complications if there are blood problems like sickle cell anemia or if a person has a weak immune system. Also, the disease can be passed from a pregnant woman to her baby. Anemia in the baby may result. In rare cases, a pregnant woman could have a miscarriage.
Most women are immune to the virus, but call your doctor if you are pregnant and have been exposed to someone with fifth disease.
