title: [Features of interepidemic influenza A and B viruses].
abstract: The comparison of interepidemic influenza viruses with the pathogens of resultant influenza epidemics has revealed that they belong to the same type (subtype) of influenza virus. A definite correlation has been found between the antigenic specificity of haemagglutinin of epidemic and interepidemic strains. The antigenic structure of the interepidemic viruses and the pathogens of further epidemics of influenza B viruses have been found to be completely identical. The interepidemic A(H1N1) isolates have been shown to be antigenic analogues of the causative agents of influenza A(H1N1) during the previous epidemics. Despite the time and place of their isolation, as well as the etiology of the previous and subsequent epidemics, the interepidemic influenza A(H3N2) viruses have been ascertained to be similar to the reference A/Bangkok/1/79.
