During the period preceding the year 1998 when the peak values of the rabies incidence were registered in the Moscow region, a noticeable increase in fox frequency and the density of their population occurred, especially in 3 endemic areas of the north-western zone. Considering the fact that this zone was endemic for rabies, an increased density of the fox population was, most probably, the critical factor of the epizootological risk and the main cause of the emergency situation in rabies in 1998. The data obtained in this investigation may serve as a real basis for the prediction of the epizootic situation.
