RESUMO
The early detection of tuberculosis is one of the priority targets in the system of anti-tuberculosis care of population, regardless of epidemiological and socio-economic conditions. The effectiveness of these activities depends on system of organization, methods of detection, quality of planning and implementing preventive examinations for tuberculosis among population. Despite decreasing of morbidity and mortality from tuberculosis in the Irkutsk oblast, it belongs to the territories with high prevalence of tuberculosis. Until 2011, the increasing of incidence of tuberculosis in the Irkutsk region occurred mainly due to increasing of effectiveness of measures of active detection of tuberculosis in population. In 2012-2019, the incidence rate tends to decrease while maintaining appropriate level of efficiency of active detection of disease. In context of improving epidemiological situation of tuberculosis, it is necessary to focus organizational efforts on active detection of tuberculosis mainly in risk groups, with simultaneous increasing of detection of disease in population by referral to medical organizations of primary medical care.
