Abstract
IntroductionThe spread of tuberculosis (TB) infection among migrants from Russian regions (RM) and other countries, and homeless (HL) has a significant impact on TB incidence in megapolis: more than 50% of new TB cases in the Moscow city (12 million population) and TB notification rate of ~25 TB cases per 100 K. A comparative description of the medical and social-demographic characteristics of nonresident new TB cases will allow clarifying of activities for TB prevention.
Methods: Data of all 11968 new TB cases registered in Moscow in 2016-2019 were analyzed. The cases included 5294 RS, 2327 RM, 627 HL, 1921 citizens from Uzbekistan and Tajikistan (UTM), mostly active detected in Migration center when applying for a work permission, 812 citizens from Kyrgyzstan (KGM), whose can work in Russia without special permission (Kyrgyzstan and Russia are members of the Customs Union).
Results: Screening provided active TB detection in 70.2% RS, 53.6% RM, 32.1% HL, 93.7% UTM and 85.8% KGM (p < 0.01 for all). Disseminated pulmonary TB (PTB) were registered in 20.0% RS, 35.6% HL, 6.6% UTM and 8.8% KGM (p < 0.05 for all). Male accounted for 59.3% RS and 84.4% HL (p < 0.01) and for 85.1% UTM and 47.9% KGM (p < 0.01). Most of RS and HL cases had age 31-50 (47.8% and 56.3%). Age of 21-30 accounted for 49.5% UTM and 53.6% KGM (p < 0.01).Unemployed TB cases accounted for 46.5% RS, and for 52.7% RM, 89.6% HL, 93.6% UTM and 76.5% KGM (p < 0.01 for all).
Conclusions: Characteristics of nonresident new TB cases is strongly depended of region of origin and the legislation specifics for migrants, which should be strictly taken into account in organizing targeted measures to prevent the spread of TB infectious in a megapolis.
