[The spatial-temporal structure of fluctuations in tick-borne encephalitis morbidity in the Maritime Territory].

The annual dynamics of the epidemic process in tick-borne encephalitis and its spread in the Maritime Territory, endemic for this infection, have been studied. The study has shown that in the central mountainous regions grown with boreal forest, in contrast to the rest of this focal area, a higher morbidity level and more severe outcomes of this infection are observed. This indicates that in those regions more ancient nuclei of the endemic area of this infection with the main stable elements of the natural focus are preserved.
