Норовирусы обусловливают вспышки острых кишечных инфекций во всем мире. Несмотря на то, что основным путем передачи норовирусной инфекции является контактный путь от человека к человеку, заражение посредством контаминированной воды также часто приводит к возникновению массовых заболеваний. Цель исследования. Провести эпидемиологический и молекулярно-генетический анализ водной вспышки норовирусной инфекции среди детей в г. Хабаровске в 2019 г. Материалы и методы. Обнаружение РНК норовирусов в образцах биологического материала осуществляли с помощью полимеразной цепной реакции. Нуклеотидные последовательности норовирусов определяли методом секвенирования. Полученные сиквенсы подвергнуты филогенетическому анализу. Результаты исследования. В июле 2019 г. в г. Хабаровске острой кишечной инфекцией заболели 34 ребенка. Эпидемиологическое расследование показало, что все заболевшие накануне играли и купались в пешеходном фонтанном комплексе. Молекулярно-генетический анализ 18 образцов клинического материала от детей с острым гастроэнтеритом и 1 образца воды из пешеходного фонтанного комплекса выявил рекомбинантный норовирус GII.P7-GII.6. Установлено 100,0 % сходство всех полученных нуклеотидных последовательностей между собой. Филогенетический анализ фрагмента ORF2 показал, что капсидный белок хабаровских штаммов GII.P7-GII.6 принадлежит к геноварианту GII^. Заключение. Наиболее вероятной причиной развития вспышки норовирусной инфекции среди детей в г. Хабаровске в 2019 г. явилась контаминация воды в пешеходном «игровом» фонтанном комплексе, произошедшая в результате отсутствия должного обслуживания и регулярных дезинфекционных мероприятий.</p></abstract><trans-abstract xml:lang="en"><p>Background: Noroviruses are common causative agents of acute gastroenteritis worldwide. Person-to-person transmission is the dominant transmission route for norovirus infection but contaminated water also often leads to outbreaks. Objectives: Our purpose was to do epidemiologic and molecular genetic analyses of waterborne norovirus infection outbreak among children in Khabarovsk in 2019. Materials and methods: Clinical and water samples were screened for the presence of norovirus RNA using real-time RT-PCR detection kit. The norovirus nucleotide sequences were determined by Sanger sequencing. The obtained sequences were subjected to a phylogenetic analysis. Results: In July 2019, 34 children developed acute gastroenteritis in Khabarovsk. The epidemiologic investigation showed that on the eve of the disease onset all patients played and bathed in a pedestrian fountain complex. A molecular genetic analysis of 18 biological samples from children with acute gastroenteritis and a water sample from the fountain revealed a recombinant norovirus GII.P7-GII.6. We established a 100.0% identity of all obtained nucleotide sequences to each other. A phylogenetic analysis of ORF2 partial sequences showed that the capsid protein of the Khabarovsk GII.P7-GII.6 strains belonged to the variant GII.6a. Conclusions: Contaminated water in the pedestrian interactive fountain complex was the most likely cause of the norovirus infection outbreak among children in Khabarovsk in 2019 associated with the lack of proper maintenance and regular disinfection measures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>норовирус</kwd><kwd>генотип GII.P7-GII.6</kwd><kwd>норовирусная инфекция</kwd><kwd>водная вспышка</kwd><kwd>острая кишечная инфекция</kwd><kwd>филогенетический анализ</kwd><kwd>norovirus</kwd><kwd>GII.P7-GII.6 genotype</kwd><kwd>norovirus infection</kwd><kwd>waterborne outbreak</kwd><kwd>acute gastroenteritis</kwd><kwd>phylogenetic analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vinjé J.
