AN EXPERIMENT TO DETERMINE THE POTENTIAL EPIDEMIOLOGICAL VALENCY OF TICKBORNE ENCEPHALITIS AND OMSK HEMORRHAGIC FEVER NATURAL FOCI IN WESTERN SIBERIA

Abstract

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 (10000(Sigma a))/6x (summary for season) and (100(Sigma a).B)/6x (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.
