Abstract: We wish to report evidence of activity of H2N, (Asian influenza A) in man two years after H3N2 strains became dominant around the world. The RaN2 epidemics of 1968-69 displaced the predecessor H2N2 strains so rapidly that within 12 months new isolations of the older strains had ceased. 1 Nevertheless, the discovery in pre1957 sera of H2N2 antibodies in persons born before 1890,2 and HaN2 antibodies in persons born before 1902,3 suggests that these strains which became dominant in 1957 and 1968, respectively, were not truly novel. It is unknown whether the ascendancy of a new major strain represents emergence of old types from an active biological reservoir, or reconstitution from genetic components that had persisted, if at all, only in other combinations [...].
