Background: Studies assessing the risk of cytomegalovirus (CMV), parvovirus B19 (B19V), rubella and varicella infections in female child-care personnel may help define appropriate preventive strategies during pregnancy.

Results: In 395 exposed and 382 reference women, CMV, B19V, rubella and varicella seroprevalence were 69.
