[Emerging and reemerging infections of Northern Eurasia: global implications].

This paper presents selected results of the studies on emerging and reemerging infections caried out in D I Ivanovsky Research Institute of Virology with special reference to comprehensive ecological, virological, and molecular-genetic analysis of the following viruses: California encephalaitis serocomplex, West Nile fever, highly virulent avian influenza A virus (H5N 1), and new pandemic influenza A vires (HIN1). Special attention is given to the role of emerging and reemerging infections at the territory of Northern Eurasia in national and world-wide epidemiological cataclysms and their prognostication for minimizing their consequences based on monitoring pathogen evolution.
