[Cytomegalovirus. Presence of antibodies in married couples]

Sera from 142 Norwegian couples were assayed for the presence of antibody to Cytomegalovirus. Sixty-four percent were seropositive and the yearly conversion rate was approximately 1.65%. The couples included significantly more seropositive women than men. This may indicate that seropositive men infect seronegative women, while seropositive women seldom infect seronegative men.
