[Influenza morbidity in the Kazakh SSR 1977-1984].
In 1977-1984, 6 epidemic outbreaks of influenza were recorded in the republic of which 2 were due to influenza A (H1N1), 2 to A (H3N2) and 2 to influenza B virus. The epidemics of influenza H1N1 (1977-1978, 1981) and H3N3 (1979-1980, 1983) were characterized by gradual decrease of their intensity as manifested by lowering of the morbidity rate and frequency of virus isolation. On the contrary, epidemics of influenza B showed a certain trend to increase. An important feature of the epidemics etiologically associated with A (H1N1), A (H3N2), and B viruses consisted in the predominant involvement of the child population.
