The spread of drug-resistant tuberculosis necessitates the implementation of novel analytical approaches for assessing epidemiological risks using wholegenome sequencing (WGS) data.</p></sec><sec><title>Objective</title><p>Objective.

The study included 5538 MTB genomes representing a wide range of genotypes from countries of the post-Soviet region. For each strain; the mutational burden in resistance-associated genes and the relative frequency of the genotype in the population were calculated. Logarithmic transformation; normalization; and aggregation methods were applied to construct a unified Integrated Epidemiological Risk Index (IERI). The predictive value of the index was evaluated using ROC analysis.</p></sec><sec><title>Results</title><p>Results. This study presents an Integrated Epidemiological Risk Index (IERI) that simultaneously incorporates the population prevalence of MTB genotypes and their mutational burden in genes associated with resistance to anti-tuberculosis drugs. ROC analysis confirmed the high predictive value of the IERI (AUC = 0.867) and the robustness of the method when applied to heterogeneous population datasets.</p></sec><sec><title>Conclusion</title><p>Conclusion. The findings demonstrate the practical utility of the IERI for early identification of high-risk strains in the context of genomic epidemiological surveillance.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Mycobacterium tuberculosis</kwd><kwd>геномный эпидемиологический надзор</kwd><kwd>риск-ориентированный эпидемиологический надзор</kwd><kwd>множественная лекарственная устойчивость</kwd><kwd>интегральный индекс эпидемиологической опасности (ИИЭО)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Mycobacterium tuberculosis</kwd><kwd>genomic epidemiological surveillance</kwd><kwd>riskbased epidemiological surveillance</kwd><kwd>multidrug resistance</kwd><kwd>Integrated Epidemiological Risk Index (IERI)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Государственной темы №121022500179-0 «Молекулярные, организменные и популяционные закономерности формирования эпидемического процесса антропонозных и трансмиссивных инфекций на территории Северной Азии и сопредельных территориях»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Global tuberculosis report.
