Overview of Epizootological and Epidemiological Situation on Brucellosis in the Russian Federation in 2017 and Prognosis for 2018

Abstract

Analysis of brucellosis morbidity rates in humans and animals across the Russian Federation in 2017 is presented. Epidemic situation on the infection is characterized as unstable, the incidence and number of people with brucellosis are reduced in reference to the average long-term indicators by more than 20 %, against the background of epizootic situation aggravation as regards brucellosis of farm animals. There are cases of group outbreaks of brucellosis in the Stavropol Territory, Lipetsk and Penza Regions. According to the Federal Service for Veterinary and Phytosanitary Surveillance, analysis of the cumulative epizootic state of the population of epidemically significant species of cattle and small cattle in 2017 defines the risk of brucellosis in the Russian Federation as “high.” In 2018, the unstable epidemic situation on brucellosis will remain; there is high probability of outbreaks with cluster human incidence, including in the territory that is free from brucellosis. Predicted for 2018 morbidity rates on brucellosis in humans will be below the level of the average long-term morbidity and may be within the range of 330–360 cases.
