[Epizootic characteristic of rabies today].

During the 23 year period rabies was registered in the Moscow region in 163 cases among foxes, 22 cases among racoon-like dogs, 92 cases among dogs, 54 cases among cats. In 1991-2000 ten cases of rabies were registered among other wild animal other than foxes and raccoon-like dogs (hares, hedge-hogs, polecats, badgers, hamsters, martens, rats). Under today conditions the generalized epizootological pattern of rabies is characterized by the vector "natural foci-->anthropurgic foci" with wild and domestic animals playing an alternative role in the epizootic process and the circulation of the infective agent.

[Frequency dynamics of foxes as a factor of epizootic risk of rabies].

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.

[Current rabies epizootiology].

Situation in rabies in the Russian Federation (RF) remains to be tense and is characterized by important specific features. Central Russia and the Moscow region have essential differences in the epizootic situation, the epizootological structure of rabies and other indices as compared with the Russian Federation. In the course of the last 25 years the ecological stereotype of rabies has undergone considerable transformations, becoming natural focal infection with the circulation of the infective agent among wild carnivores, which is now particularly obvious in the Moscow region.
