[The effect of socioeconomic and ecological conditions on tick-borne encephalitis morbidity in settled regions].

A relation between the tick-borne encephalitis morbidity, to the cattle-breeding methods and specific and quantitative structure of dairy cattle herds in developed regions is discussed. This relation is due to the fact that cows and goats are Ixodid hosts and donors of the virus. The factors like use of ameliorated pastures in cattle-breeding practice and cattle maintenance in the stalls deprive ticks of their hosts and donors of virus. It brings to decrease of vector density, valence of foci and human morbidity. On this basis, the prognosis of human morbidity in Byelorussia is given for the following decade.
