[Epstein-Barr virus infections in pregnancy. The serological profile of active infections in pregnant women. Their possible relationship with perinatal mortality (author's transl)].

A significant number of cases of deaths and of perinatal misfortunes are still of unknown origin. The role of pathological infection is probably important in these cases and particularly those in the Torch group of viruses, and among these, as has been shown by epidemiological and virological tests, the Epstein-Barr virus (E.B.V.). The authors have undertaken a prospective study based on serology, looking for E.B.V. antibodies in pregnancy. 1,164 women were studied and 74 of these had perinatal abnormalities. There is a significant relationship between active E.B.V. infection and mishaps in pregnancy.
