title: [3 cases of isolating the influenza A virus with human hemagglutinin Hsw1 in 1983 in Alma-Ata].
abstract: In the interepidemic period of late 1983 in Alma-Ata, influenza viruses with hemagglutinin of the swine subtype and neuraminidases N1 and N2 were isolated from humans. One of the strains, A/Alma-Ata/1044/83 (Hsw1N1), was isolated from the lungs of a man of 65 with the diagnosis of influenza and disseminated intravascular syndrome who had had communal and occupational contacts with swine. In paired sera of a sick child, and in seroepidemiological screening for influenza antibodies to swine influenza virus in low titres were detected in 34% of cases in subjects under 40. Radioimmunoassay of blood clots from subjects of the same focus revealed in one specimen the presence of swine influenza antigen.
