Fifth disease, caused by a parvovirus, is so called because it is the fifth in a group of six childhood diseases that cause rash and fever. The symptoms of rash and fever are generally mild and frequently go unnoticed. It is uncommon to develop fifth disease during pregnancy. Most women are in fact immune, having been infected as children without being aware of the infection.
Very rarely, infection with fifth disease during pregnancy increases the risk of an early miscarriage or a rare form of fetal anemia. It is best to follow your practitioner’s advice in your situation, but you and your baby are likely to be completely unaffected.
