Effectiveness of antiepidemic events in tuberculosis in context of changing epidemic process trend

Abstract

Objective. To study the features of the formation of the epidemic situation for tuberculosis and to evaluate the effectiveness of antiepidemic events in separate age groups. Materials and methods. A retrospective analysis of the incidence of tuberculosis in Rostov-on-Don from 1992 to 2017 was conducted. The dynamics of the incidence of active tuberculosis, respiratory system tuberculosis and forms with bacillus discharge with the determination of the trend and its quantitative assessment was studied; the age structure of tuberculosis patients was analyzed depending on the direction and severity of the trend. Results. The incidence of tuberculosis has been increasing in Rostov-on-Don since 1993, and from 2003 to 2008, the average long-term incidence of active tuberculosis, respiratory tuberculosis and forms with bacillus excretion was maximum. Since 2009, the direction of trends has changed, the period from 2009 to 2013 is characterized by a "pronounced" downward trend and since 2014, the incidence rates have been minimal. In the age structure of patients with active tuberculosis, the proportion of persons aged 40-49 is decreasing, and in 20142017, the proportion of persons aged 5059 years is also falling. Since 2009, the proportion of persons aged 1829 has increased, and in 20092013 the proportion of children has grown. In 20142017, the proportion of persons over 60 years of age increased among those who fell ill. Conclusion. The most effective events are carried out in the group of 4059 years, less effective among children and persons aged 1517 and 3039 years. The results of the research will allow us to adjust preventive measures among children, teenagers and young people.
