Abstract
Based on the actual situation in the CCHF natural foci of Kazakhstan for the first half of 2013, the authors, using EIDSS version 4, evaluated the accuracy of the earlier prognosis of situation development in the CCHF natural foci of Kazakhstan for 2013 (EIDSS Application for CCHF Foci Activity Epi-Analysis and Prediction in Kazakhstan). The prognosis of situation development in 2013 for 11 districts of Kazakhstan (estimated in 2012 as the districts with a high risk of CCHF) proved to be accurate in 90.9% of cases.
