Distribution of influenza viruses in Northern Greece during 1972-1983.
Observations on the circulation of influenza viruses in Northern Greece during the winters of 1972/3 to 1982/3 are presented. Influenza A viruses were detected every winter with the exception of those of 1973/4 and 1981/2, when neither type A nor type B was isolated. The strains of type A isolated during the study period were similar to those circulating world-wide over the same time scale. Influenza B viruses were isolated only during the winters of 1972/3 and 1979/80; influenza A viruses were also circulating in the community at those times. The B strains detected were similar to those recorded world-wide during the period of study.
