[Prevalence of antibodies to cytomegalovirus in a population of blood donors from the Paris region].

Prevalence of antibody to cytomegalovirus (CMV) was determined in a parisian population of blood donors. Among 7,729 subjects, 3,048 are men (39.4%), 4,681 are women (60.6%), 3,615 were positive for anti-CMV antibody (47%) and 4,114 were seronegative (53%). 9.1% of the whole population had a high blood concentration of the antibody (superior to 12 international units per liter) and were able to give for specific immunoglobulins. The study of the influence of age and sex showed that men aged less than 40 years were more frequently seronegative, while women aged more than 40 years had more frequently high anti-CMV titers. There are no influence of the ABO and Rh blood groups on the frequencies of seropositive and seronegative blood donors.
