[Rubella in Vojvodina. VI. Serologic status of women of reproductive age during the time of endemic manifestations of rubella 1978-1985].

In first phase of a study on congenital Rubella syndrome incidence in Vojvodina population, we examined serologic status of 1225 non-pregnant and 846 pregnant women of generative age, as well as the level of exposure to the Rubella virus. On the basis of antihemagglutinin antibody titre 93.2% of women were found to have antibody titre level above or equal to 1/8. There were no significant differences between the proportions of seropositive women in different age groups (x2 = 1.20; P = 0.88). The percentage of seropositive women varied from 82 to 97% (x2 = 29.85; P = 0.005), according to the year of the investigation. The lowest percentage was registered (1980). Rubella virus susceptibility index was 13.1%. On the basis of proven seroconversion the examination of even Rubella serum samples showed the morbidity rate of 7.18%. The level of exposure of pregnant women to the Rubella virus was 71.0%, during all the period of pregnancy. In such circumstances total Rubella morbidity of pregnant women was 2.13%; the highest level, 21%, was in persons form 18 to 19 years of age. It was not possible to make an analysis of pregnancy outcomes and the consequences in pregnant women.
