В большинстве случаев наблюдаются симптомы острой респираторной вирусной инфекции, такие как лихорадка, кашель, миалгия или слабость, которые протекают легче, чем у взрослых пациентов. Кроме того, большинство результатов лабораторных и рентгенологических исследований у детей с COVID-19 неспецифичны. Однако у некоторых детей могут развиваться затяжные формы заболевания, а также сохраняться долговременные симптомы (постковидный синдром) после перенесенной инфекции, существенно влияющие на качество жизни. Имеются различные данные о распространенности и продолжительности отдаленных последствий новой коронавирусной инфекции у детей. Наиболее распространенными симптомами после COVID-19 у детей и подростков являются усталость, отсутствие концентрации внимания, мышечные боли. В обзоре представлены последние данные литературы о длительности и особенностях течения COVID-19 у детей. Следует помнить, что длительно существующие симптомы могут повлиять на физическое, социальное и психологическое благополучие детей и подростков в будущем. </p></abstract><trans-abstract xml:lang="en"><p>The novel SARS-CoV-2 coronavirus infection is predominantly asymptomatic or presenting few symptoms in children, and life-threatening complications are rare. In most cases, symptoms of ARVI are observed, such as fever, cough, myalgia, or weakness, which are milder than in adult patients. In addition, most laboratory and radiographic findings in children with COVID-19 are nonspecific. However, some children may develop prolonged forms of COVID-19, as well as long-term symptoms (post-COVID syndrome) after the illness, which significantly affect the quality of life. There are different data regarding the prevalence and duration of long-term effects of a new coronavirus infection in children. The most common symptoms following COVID-19 in children/teens are fatigue, lack of concentration, and muscle pain. The review presents the latest literature data on the duration and course of COVID-19 in children. It should be remembered that long-term symptoms could affect the physical, social, and psychological well-being of children and adolescents in the future. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>SARS-CoV-2</kwd><kwd>длительный COVID-19</kwd><kwd>постковидный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>SARS-CoV-2</kwd><kwd>long COVID-19</kwd><kwd>post-COVID syndrome</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">WHO Director-General’s opening remarks at the media briefing on COVID-19 — 11 March 2020. https://www.who.int/director-general/speeches/detail/who-director-generals-opening-remarks-at-the-media-briefing-on-covid-19--- 11-march-2020.
