Title: The incidence of tuberculosis among labour migrants in Russia

Abstract

Introduction:
Over the past 20 years, there has been a steady decline in the incidence of TB among the resident population in Russia. At the same time, over the past 10 years, there has been a significant influx of labor migrants in Russia, which increases the risk of the spread of tuberculosis, imported by migrants from those countries in which its considerable spread among the resident population is observed. 
Objective of the study: to analyze the incidence of TB among labor migrants in Russia in dynamics for the period from 2010 to 2019. Materials and methods: information from Rosstat forms for 2010-2019 and the Federal Migration Service for 2019. The Chi-square Criterion (?2) Pearson was used for the analysis. 
Results. The spread of TB among labor migrants in the constituent entities of the Russian Federation over the past 10 years was characterized by pronounced unevenness, while the largest number of migrants, who for the first time fall ill with TB in 2019, was recorded only in 16 constituent entities of the Russian Federation, which was 19% of their total number. This situation was due to the high demand for the creation of new jobs in these constituent entities of the Russian Federation, for example, in three of them - Moscow, St. Petersburg and the Moscow region, 59% of all TB cases among labor migrants were registered. An increase in the incidence of TB among labor migrants leads to a slowdown in the rate of decline in the overall incidence of TB, which is a key indicator of the TB Elimination Program, that may have a negative impact on the achievement of the Program's target indicators in these 16 constituent entities of the Russian Federation. Comparison of the age distribution of newly diagnosed TB patients among the resident population and labor migrants revealed significant differences due to the concentration of TB patients from the number of labor migrants among the youngest age groups 18-24 and 25-34 and their almost complete absence in older age groups ?55 years, in contrast to the resident population, among which the largest number of TB patients was observed in older age groups ?45 years. Comparison of the TB incidence rates among the resident population and labor migrants, carried out in 10 constituent entities of the Russian Federation with the highest prevalence of TB among labor migrants, showed that in all of them the TB incidence rate among labor migrants was many times higher than those among the resident population (p <0,0001). 
Conclusion: a significantly higher incidence of TB among labor migrants creates a serious threat to the infectious safety of the resident population in those constituent entities of the Russian Federation where the largest influx of labor migrants is observed.
