[The immune status of the population of the Crimea to the tick-borne encephalitis virus].

The immune status of the Crimean population with respect to tick-borne encephalitis (TBE) virus has been studied. The results of the study confirm the existence of natural foci of TBE in the Crimea. The most active and potentially dangerous foci are located in forests of the mountain area of the peninsula. The study has revealed that humans are mainly exposed to the risk of contacting TBE virus infection during their work and rest in the forest.
