[Typifying foci of tick-borne encephalitis in the pre-Baikal]. / K voprosu o tipizatsii ochagov kleshchevogo entsefalita v Predbaikal'e

The existence of tick-borne encephalitis foci of several landscape types was revealed in the Prebaikalye. Of particular interest were foci of the forest-steppe type, in which virus strains of the Western serological type circulated along with the Eastern serological type strain of the tick-borne encephalitis virus. It was shown that infection of man was possible not only by transmissive, but also by the almientary route--through cow milk.
