Rubella (German Measles) is a highly contagious viral illness with symptoms very similar to rubeola (red measles, commonly referred to simply as "measles") but differs in the severity of symptoms and length of illness. The most serious threat of rubella is to the pregnant female who has never had rubella. If exposed to rubella, she can contract the disease which can cause serious problems for the unborn baby.

Parvovirus B19 Exposure in Pregnancy

Typically, there is no serious complication for a pregnant woman or her baby from exposure to a person with Parvovirus B19, or "Fifth" disease. About 50% of women are already immune to Parvovirus B19, so these women and their babies are protected from infection and illness. Even if a woman is susceptible and gets infected with Parvovirus B19, she usually experiences only a mild illness. Likewise, her unborn baby usually does not have any problems attributable to a Parvovirus B19 infection.

Parvovirus B19

Parvovirus B-19 infection is also known as Fifth Disease. Fifth Disease is usually a mild illness that resolves without medical treatment among children and adults who are otherwise healthy. However, pregnant women who are infected with Parvovirus during early pregnancy have a 5% risk of miscarriage. (Also see article Parvovirus B19 Exposure in Pregnancy.)
