Data on the incidence of brucellosis and main trends in the development of situation on this infection in countries around the world under current conditions are provided in the review. A detailed analysis of epizootiological and epidemiological situation regarding brucellosis in the Russian Federation over the last decade and a forecast for human brucellosis incidence for 2024 are given. It is established that global situation on brucellosis in different regions of the world has undergone changes over the past 15–20 years. One can observe an almost twofold increase in the number of countries affected by brucellosis in the world. A relatively high brucellosis morbidity rates were recorded in some countries in Africa, Central Asia, South and South-East Asia, Central and South America. In countries of the European Union, there is a trend towards an increase in the number of human brucellosis cases associated with travel to enzootic countries. In the Russian Federation, an unstable epidemiological situation has been observed over the past 10 years. 3537 cases were identified. In 2022–2023, an emerging trend towards an increase in incidence of brucellosis among population by 30–50 % as compared to long-term average values was recorded, linked to occurrence of cattle epizooties, including at large livestock enterprises; formation of group epidemic foci in previously relatively brucellosis-free territories of the Central, Volga and Southern Federal Districts; and the deterioration of epizootic situation on brucellosis in the Republic of Dagestan and a number of constituent entities of Siberian Federal District. Situation on brucellosis in the Smolensk and Bryansk Regions requires closer attention. There are signs of rooting (enzooty) and further spread of brucellosis among cattle there in 2023. In 2024, incidence rate can be predicted to be 35–40 % higher than the long-term average values. The number of human brucellosis cases may be approximately 480–530 (0.32–0.36 per 100 000 population).
