title: [Etiology of influenza in Poland during the epidemiologic season 1991-1992].
abstract: Between October and April 1992 about 260,000 influenza cases were registered in Poland. This figure was much lower than in the previous season (2,000,000 cases). Most of the cases were registered in February 1992. The total mortality was 0.11 per 100,000 persons. Nine strains were isolated: eight strains A (H3N2) and one strain B. Analysis proved: eight strains A (H3N2) were related to strain A/England/261/91, A/England/427/88 and A/Beijing/352/89. One strain B was similar to strain B/Panama/45/90.
