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.)

Exposure to Resistant Bacteria in Pregnancy

VRE (Vancomycin Resistant Enterocci) and MRSA (Methicillin Resistant Staph Aureus) are common in hospitals. Staph is a normal bacteria on human skin and Enterocci are normal bacteria in the human bowel. Patients who have been hospitalized for long periods develop resistant bacteria as a result of exposure to many antibiotics or the hospital environment. In recent years resistant organisms have become very common in the community and patients often bring them into the hospital.
