[The epidemiological patterns of rubella and the ways to improve epidemiological surveillance]. / Epidemiologicheskie zakonomernosti krasnukhi i puti sovershenstvovaniia épidemiologicheskogo nadzora.

The retrospective epidemiological analysis of rubella morbidity in Perm has revealed that the epidemic process of rubella is revived every 2-3 years in winter and spring. Children of preschool age in organized groups are mainly affected; 42.5% of these children have no specific antibodies. Among adults, the risk group consists mainly of women aged 20-29 years. The intensity of the epidemic process of rubella in organized groups of children has been found to depend on the general level of collective immunity. The hemagglutination inhibition test with the use of rubella antigenic diagnosticum may be recommended for practical use in the system of epidemiological surveillance for the differential diagnosis of rubella with a view to distinguish it from other infections, the determination of the scope of the virus circulation among different groups of the population and the timely diagnosis of rubella in pregnant women.

[Immune structure and rubella incidence in pregnant women in Moscow]. / Immunostruktura i zabolevaemost' krasnukhoi u beremennykh zhenshchin Moskvy.

The immune structure of the Moscow City population (mostly, pregnant women) in relation to rubella virus antigen. Specific antihemagglutinins were found in 82%-93% of pregnant women, depending on their age. Examination of sera from 207 pregnant women who had contacts with rubella patients demonstrated clinically manifest rubella verified serologically in 9.2%, and asymptomatic form of rubella in 8.6%. By an immunochemical method (treatment of sera with staphylococca reagent) specific rubella IgM were found in 7 (100%) pregnant women who had experienced clinically manifest rubella, and in 6 (14.3%) pregnant women with asymptomatic rubella.
