Is primary cytomegalovirus infection an occupational hazard for obstetric nurses? A serological study.

The results are reported of a 4-year prospective study of the incidence of primary cytomegalovirus (CMV) infection in the nursing staff of a specialist obstetric hospital. The absence of seroconversion found in personnel attending patients with confirmed CMV-infection justifies reassuring staff members in "high-risk" areas of the adequacy of the methods used to combat cross-infection. On the other hand, a low rate of seroconversion (1.2% per annum) in the staff who nurse normal mothers and "rooming-in" babies emphasizes the need for the rigorous observance of hygienic precautions by all personnel in all areas. The results of this Australian investigation are discussed in relation to the northern hemisphere experience of CMV-seroconversion in pediatric nurses.
