[Modern problems in the study of tick-born encephalitis natural foci].
A new conception of natural focus as anthropo-parasitic system is given by an example of tick-born encephalitis. Problems of natural foci classification and zoning of focal territories, as well as patterns of ecological relations in these systems, are considered. Causes and factors affected expansion of the infection are analyses.
