It is suggested that potential epidemiologic valence of foci of tickborne encephalitis and Omsk hemorrhagic fever be evaluated by the number of virus-carrying ticks per 1 hectare. The latter is determined by the formula 10000Sigma a6x summary for season and 100Sigma a.B6x in the period of peak, where A is the sum of 10-day average indices of tick abundance per 1 km of the route with blanket dragging or the density of ticks per 1 km during the period of peak in the 2nd formula and B is the percentage of virus-infected ticks among the latter.
