[Epizootics of "avian" influenza as the manifestation of pandemic].
In this review of literature modern notions on the role of birds in the evolution of the pathogenicity signs and immune system of the main and intermediate hosts of influenza viruses, as well as on the mechanisms of overcoming interspecific barriers, are analyzed. The chronology of the spread of "avian" influenza among humans, starting from 1997, the properties of the natural reservoir of this infection, and in particular influenza viruses A, the ways of their variability and evolution are presented. The conclusion has been made that the mixing, joint evolution, recombination and reassortment of viral genomes may be caused by global events in individual geographical regions.
