Abstract

Objective: Epidemiological data analysis concerning the spread of brucellosis in Russia and Primorsky Region, study of the manifestations of the epidemic process and the current state of brucellosis issue.

Methods: Descriptive epidemiological analysis of materials on infectious morbidity based on state statistical reporting forms No. 1, No. 2 “Information on infectious and parasitic morbidity”.

Results: Brucellosis affects workers in the main occupational groups of livestock breeders, workers involved in the processing of livestock, who contact sick animals and other sources of brucellosis infection. Primorsky Region is a territory with an unstable epidemiological situation on brucellosis. A different morbidity rates were registered over the years. However usually it does not exceed the national average rate. In 2009, the morbidity rate counted 27.5% less than in Russian Federation (0.21 and 0.29 per 100,000 respectively), compared to previous years, the average long-term morbidity rate in the region increased by 3.5 times. The disease rate for the period from 2009 to 2019 ranged from 0.05 to 0.21%. In 2012, it exceeded the index in the Far Eastern Federal District (0.1 per 100,000 population). Brucellosis cases were detected among livestock breeders during an extraordinary medical examination due to the bad situation on brucellosis among animals.

Conclusions: In recent decades, the epizootic and epidemiological situation on brucellosis remains tense due to the decrease in the number of serological and bacteriological studies among animals and humans, the weakening of veterinary-sanitary control and the formation of new private farms.
