[Virologic and seroepidemiologic analyses of the circulation of influenza virus A(H1N1), similar to serovariant A(Hsw1N1), in 1984-1985 in Alma-Ata].

The study made with the use of virological, seroepidemiological, radioimmunological and immunological techniques revealed that influenza virus A, antigenically similar to influenza virus A/swine/Iowa/15/30, circulated in Alma-Ata in 1984-1985. The role of these viruses in the seasonal rise of influenza morbidity at the end of 1984 was established. From nasal washings and blood clots obtained from patients, as well as from dissection material, 12 strains were isolated. These strains were similar to serovariant A/swine/owa/15/30 and differed from influenza virus A/New Jersey/76.
