The effects of human parvovirus B19 and cytomegalovirus during pregnancy.

Human parvovirus B19 and cytomegalovirus (CMV) are two common viruses that can have significant and devastating effects on a fetus. Maternal infection may lead to vertical transmission of the virus to the fetus. Parvovirus infection in the fetus may cause miscarriage, nonimmune hydrops, or demise. Fetal CMV infection can cause a number of problems, including nonimmune hydrops and neurosensory disabilities. Nurses who are knowledgeable about possible viral effects during pregnancy can collaborate in the management of these patients, particularly in the areas of patient assessment, education, and support.
