Background: About 50% of new TB cases (NC) in Moscow city are migrants (mostly “labor migration”), internal (from other Russian regions, IM) or external (foreigners, EM), which consist of former USSR and other countries (FSC and OC) cases. FSC includes ones detected at the City Migration Center for work permition by screening (FSC-S), and passive detected cases (FSC-P). Aims: Analysis of characteristics of NC in different migrant groups. Methods: 5704 new TB cases, registered in 2017-2018 in Moscow, including 1224 IM, 1745 FSC, 113 OC and 2622 residents (RS) were analyzed. Treatment outcomes analysis based on 2017 cohorts of non-MDR TB cases (1494 IM&EM and 1115 RS). Results: FSC included 85.1% active detected cases (FSC-S) vs 52.0%, 44.4% and 73.1% in IM, OC and RS, accordingly. 90.5% of FSC-S was unemployment, involved in mandatory screening before the recruiting vs 56.7%, 43.4%, 44.9% and 51.1% in FSC-P, OC, RS and IM. 40.7% of OC was students. Most migrants (62.8% IM, 59.2% FSC-P, 70.9% FSC-S, 66.4% OC) were 21-40 y.o. vs only 42.0% in RS (p 18.9% IM, 26.9% FSC-P, 17.0% OC, 20.4% RS vs 6.0% FSC-S (p TB/HIV obtained in 13.0% IM, 10.6% FSC-P, 1.8% OC, but 0.3% FSC-S and 19.6% RS (both p Treatment effectiveness (TE) for IM&EM was 47.6% with 49.3% lost for follow up (LFU), while for RS this rate were 88.0% and 2.2%. TE for cohorts not included LFU was 93.9% in IM&EM and 89.9% in RS (p>0.05). Conclusions: Moscow NC consists of different groups of migrants, each with demographics and detection particularities, essential for proper allocation of resources for TB control in the city. |
