Determine spread of hepatitis C vims genotypes, circulating in Moscow Region over the last decade. Materials and methods. The presence of HCV RNA, genotype and subtype of the vims were determined in blood sera samples obtained in 2006 - 2014 from 2847 individuals with the presence of HCV infection, who had or did not have injectable dmg administration in anamnesis. Results, lb and 3a remain the main subtypes, circulating in the population over the last decade. A notable reduction of la subtype circulation took place among injectable dmg users (IDU). Recombinant form RFl_2k/lb of hepatitis vims is present only among this risk group and constitutes 2% of the overall amount of subtypes in both 2007 and 2014. Genotype 4d was detected in 2014, that is not typical for Russian Federation. Genotype 3a is dominant in IDU age groups of 20 - 29 and older than 40, and in the 30 - 39 group the main - subtype lb. Phylogenetic analysis has shown the lack of certain genetic variants of subtypes lb and 3a, characteristic for IDU, that gives evidence on a wide circulation of the main subtypes of the vims in the whole population of individuals, infected by HCV. Conclusion. Spread of main genotypes/subtypes of HCV in the overall population and among IDU in Moscow remains stable over the last decade.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Определить распространенность генотипов вируса гепатита С (ВГС), циркулирующих в Московском регионе на протяжении последних десяти лет. Материалы и методы. Определяли наличие РНК ВГС, генотип и субтип вируса в собранных в 2006 - 2014 гг. образцах сыворотки крови от 2847 лиц с наличием ВГС-инфекции, имевших и не имевших в анамнезе употребление инъекционных наркотиков. Результаты. На протяжении последних 10 лет основными субтипами, циркулирующими в популяции, остаются lb и За. Произошло заметное снижение циркуляции субтипа 1а среди потребителей инъекционных наркотиков (ПИН). Рекомбинантная форма вируса гепатита RFl_2k/lb присутствует только среди данной группы риска и составляет 2% от общего количества субтипов как в 2007, так и в 2014 гг. В 2014 году выявлен генотип 4d, который не характерен для территории РФ. Среди ПИН в возрастных группах 20 - 29 и старше 40 лет доминирующим субтипом является За, в группе 30 - 39 лет основным - субтип lb. Филогенетический анализ показал отсутствие определенных генетических вариантов субтипов lb и За, характерных для ПИН, что свидетельствует о широкой циркуляции основных субтипов вируса во всей популяции инфицированных ВГС лиц. Заключение. Распределение основных генотипов/субтипов ВГС в общей популяции и среди ПИН в Москве остается стабильным на протяжении последних десяти лет.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hepatitis C vims</kwd><kwd>genotype</kwd><kwd>injectable dmg users</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вирус гепатита С</kwd><kwd>генотип</kwd><kwd>потребители инъекционных наркотиков</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Антонова Т.
