[Virological and pathomorphological study of an influenzal infection in children 1982-1983]

In the interepidemic period of 1982-1983, acute respiratory viral infections and pneumonias in infants in Alma-Ata were in 40.2% of cases etiologically associated with influenza infection. In the studied period in Alma-Ata and during an epidemic outbreak of influenza in Kzyl-Orda (March, 1983), two influenza A virus subtypes, H1N1 and H3N2, were in circulation. In a number of cases these subtypes were isolated from the same infants.
