INVESTIGATION OF A FOCUS OF BRUCELLOSIS AMONG ANIMALS AND PEOPLE IN THE REPUBLIC OF TATARSTAN

Over the past 3 years, the Russian Federation has seen an increase in the incidence of newly diagnosed brucellosis. The problem of brucellosis remains important in regions with developed livestock farming; however, cases of diseases in animals and humans can also be recorded in other regions of the country. The article describes an outbreak of brucellosis in a peasant farm in the Novosheshminsky municipal district of the Republic of Tatarstan, affecting 148 heads of cattle and 4 farm employees. The disease was caused by Brucella abortus. An analysis of maps of the epizootic and epidemiological survey of the outbreak, acts on the sanitary and epidemiological survey, and sanitary and hygienic characteristics of the working conditions of workers was carried out. Data from the case histories of 4 peasant farm workers with brucellosis are also presented. The most likely cause of the epizootic was the unauthorized import of cattle, and human diseases were caused by non-compliance with working conditions and personal protective measures for farm workers. Conclusion: Cases of brucellosis in our days are more often recorded in endemic areas. However, with defects in veterinary and sanitary control in any territory, epizootics are possible, which pose a serious danger both in terms of the damage they cause to the national economy and the possible infection of people, primarily belonging to professional risk groups. The disease does not have pathognomonic symptoms and can be suspected only if doctors are alert, evaluate the results of preliminary and periodic medical examinations with laboratory examinations of “at-risk” populations, and subject to a thorough collection of epidemiological history.
