An analysis of the displacement mechanism of predecessors by a pandemic strain

Abstract

The relationship between pandemic morbidity and the shared participation of a pandemic variant in epidemic process has been studied based on the example of the first pandemic wave of the A(H1N1)pdm flu in Russia (2009–2010). The selection of the relationship type of variants and transfer of the self-regulation concept of the epidemic process to the development mechanism of pandemic wave has been substantiated. The role of the genetic drift of the pandemic strain has been explained.
