Анализ развития эпидемии COVID-19 в Российской Федерации показывает, что основными показателями, способствующими возникновению подъемов заболеваемости, являются сезонный фактор, недостаточный уровень коллективного иммунитета и распространение новых геновариантов вируса SARS-CoV-2, характеризующихся высокой контагиозностью. Цель работы – анализ природных, биологических и социальных факторов, способствующих возникновению новых подъемов заболеваемости COVID-19 в Российской Федерации. Рассмотрена эпидемиологическая ситуация по COVID-19 в мире к середине 2022 г. Проанализирована роль природных, биологических и социальных факторов при распространении COVID-19 в Российской Федерации. Показано, что возникновению новых подъемов заболеваемости в наибольшей степени способствует появление новых высококонтагиозных вариантов вируса SARS-CoV-2 и сезонный фактор. Сделано предположение о том, что шестой и седьмой подъемы заболеваемости COVID-19 в Российской Федерации пройдут по оптимистическому сценарию, который предусматривает распространение высококонтагиозного варианта вируса SARS-CoV-2 со сниженной вирулентностью.</p></abstract><trans-abstract xml:lang="en"><p>Morbidity surveys in certain regions during the COVID-19 pandemic have established that the infection spreads in a wave-like manner characterised with peaks and troughs in incidence. According to the analysis of COVID-19 epidemic development in Russia, surges in COVID-19 infections are mainly driven by seasonal factors, insufficient herd immunity, and emerging SARS-CoV-2 variants with increased transmissibility. The aim of the study was to analyse environmental, biological and social factors contributing to new rises in COVID-19 cases in Russia. The study covers the global epidemiological situation as of mid-2022 and the role of environmental, biological, and social factors in the spread of COVID-19 in the Russian Federation. The results suggest that new highly contagious SARS-CoV-2 variants and seasonality are the principal factors driving new rises in morbidity. The authors assume that the sixth and the seventh COVID-19 waves in Russia will be in line with the best case scenario, which predicts the spread of a SARS-CoV-2 variant with increased transmissibility and reduced virulence.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>вирус SARS-CoV-2</kwd><kwd>вариант вируса</kwd><kwd>коллективный иммунитет</kwd><kwd>контагиозность</kwd><kwd>вирулентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>SARS-CoV-2 virus</kwd><kwd>virus variant</kwd><kwd>herd immunity</kwd><kwd>transmissibility</kwd><kwd>virulence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was performed without external funding.</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">Акимкин ВГ, Попова АЮ, Плоскирева АА, Углева СВ, Семененко ТА, Пшеничная НЮ и др.
