2023 № 2 Epidemiology of tuberculosis in Russia and Rno-Alania during the COVID-19 pandemic
The study of the combination of diseases at the present stage of development of medicine is extremely relevant. Among the combined effect of various pathologies on humans and populations, two main concepts are distinguished: comorbidity (the combined effect of diseases on a patient or group), including the underlying and concomitant diseases, and syndemia (the combined effect of diseases at the population level).
P u r p o s e : to analyze the epidemiology of tuberculosis during the COVID‑19 pandemic to identify trends in Russia as a whole and in North Ossetia-Alania.
M e t h o d s : a theoretical analysis of the current research situation in Russia in relation to the tuberculosis and COVID‑19 syndemics was carried out. The data sources were annual forms of federal statistical observation.
R e s u l t s : Significant factors that slow down the dynamics of improving the epidemic situation for tuberculosis in Russia and North Ossetia-Alania are the reduction in the coverage of the population with preventive examinations for tuberculosis. In general, a clear syndemic between the epidemiology of TB and the COVID19 pandemic has not been identified both for Russia and according to the results of the analysis of statistics in RNO Alania. There are social trends to reduce the coverage of the population and belated primary treatment of patients with a general practitioner and phthisiatrician, as well as persons removed from the dispensary, so there is an increase in the proportion of severe forms of TB (with lung tissue destruction, fibrous-cavernous type).
C o n c l u s i o n s : The identified trends indicate a later appeal of patients during the pandemic and a decrease in population coverage in Russia and in the analysis of data for North Ossetia-Alania. The increase in the proportion of severe forms of tuberculosis is more likely to be associated with the above trends, and not with syndemic. Trends in the dynamics of TB indicators in Russia and North Ossetia-Alania are similar in terms of comparing negative or positive increases in indicators.
