Comparative Analysis of Features of Epizootiological and Epidemic Situation and Risk of Rabies Infection in the Russian Federation in Early XXI Century

Abstract

The review provides an analysis of the current rabies epidemic situation in the Russian Federation and describes the dynamics of epizootic indicators, such as the epizootic index and infection density. The risk of rabies infection and the characteristics of the epizootic process in various regions of the country were studied. In 2012–2018 in comparison with 2000–2011, a 1.5–fold decrease in the activity of the epizootic process was noted, despite the expansion of the virus areal. The decrease in human hydrophobia morbidity in reference to the long-term average of 3–5 times was revealed. An increase in the value of the dog, cat and raccoon dog in human infection and a decrease of the fox role in this process have been established. The risk of rabies infection remained in almost all regions of the country. During 2012–2018 safe regions were the Arkhangelsk, Murmansk, Irkutsk, Sakhalin, Kamchatka Territory. In the Kaliningrad Region, animal cases have stopped since 2013 due to the successful use of oral vaccination of wild predators as an effective method of combating natural foci of rabies. In 2019, 3 lethal cases of lissavirus infection were recorded: two after bat bites in the Amur Region and Primorsky Territory, and one in the Moscow Region imported from Tajikistan after a dog bite. Typical cases of rabies in Russia associated with terrestrial mammals were not detected in 2019.
