Abstract

The role of the sexual transmission of human cytomegalovirus (CMV) as a cause of congenital infection was investigated. Serum samples were collected from 756 pregnant women at 10 to 12 weeks of gestation and at 32 to 36 weeks of gestation. Serum samples were also obtained from the husbands of women who seroconverted and women who were seronegative during pregnancy. Commercially available enzyme immunoassay kits were used to detect serum IgG, IgM, and IgA antibodies against CMV. CMV from neonatal urinary specimens was isolated according to a standard tissue culture technique, using MRC-5 cells. At 10 to 12 weeks of gestation, 634 of the 756 pregnant women (83.9%) had IgG antibody to CMV. At 32 to 36 weeks of gestation, 642 of the 756 women (84.9%) had IgG antibody to CMV. A meaningful rise of serum IgG-antibody titer (seroconversion) occurred in 8 women (1.1%). CMV was isolated from the urine of an infant born to a seroconverted woman within a week after birth. The prevalence of IgG antibody to CMV was significantly higher in the husbands of women who seroconverted during pregnancy than in the husbands of the women who were seronegative during pregnancy (P < 0.01). Understanding the epidemiology of CMV is a key element in the development of strategies for the prevention of infection. The transmission of CMV by sexual contact may be important in the pathogenesis of congenital infection. Entirely new approaches to the prevention and treatment of congenital CMV infection are necessary, including antiviral interventions and the development of a vaccine strategy.
