Brucellosis Incidence in Russia: Situation Analysis, Unresolved Problems and New Threats

The analytical review presents information on current situation on brucellosis in the Russian Federation. According to long-term data, on average, more than 400 cases of brucellosis among population are registered in Russia annually; incidence rate per 100 thousand population is 0.29. More than 70 % of brucellosis cases were detected in the territory with active cattle breeding in the south of the European part of the country. Since 2022, there has been an increase in the number of human brucellosis cases in regions with developed livestock farming in territories enzootic for brucellosis (mainly the Republic of Dagestan) and in previously relatively safe entities (Bryansk, Smolensk Regions, the Republic of Tatarstan, Penza Region, Krasnoyarsk Territory). In 2024, 530 cases of brucellosis were registered (0.36 per 100 thousand population), which exceeds the average long-term indicators by 27, 4 %. The emergence of group epidemic outbreaks among professional contingent at public sector farms and “family” epidemiological foci on private subsidiary farms can be considered as new threats in terms of brucellosis. Taking into account the development trends of the situation on brucellosis, in 2025, the incidence rate is predicted to be 30–40 % higher than average long-term level, which may amount to 480–530 new cases (0,32–0,36 per 100 thousand population).
