У детей заболевание часто протекает в бессимптомной и легкой формах. Однако опасность развития тяжелого течения ^VID-W характерна для детей из групп риска. Факторами риска развития тяжелых форм новой коронавирусной инфекции служат новорожденность и ранний возраст; наличие врожденных пороков развития и сопутствующих заболеваний, в первую очередь сопровождающихся иммунодефицитными состояниями различной этиологии (онкологические и аутоиммунные заболевания, сахарный диабет). В статье представлены два клинических случая COVID-19 у детей с острым лимфобластным лейкозом. Показано, что у детей с сопутствующей онкогематологической патологией новая коронавирусная инфекция может протекать как в легкой, так и тяжелой формах.</p></abstract><trans-abstract xml:lang="en"><p>Currently, the researchers from various countries have demonstrated that COVID-19 in children is diagnosed less frequently, and the course and severity of the pathological process is less pronounced than in adults. Children with COVID-19 often have asymptomatic and mild forms. However, the risk of developing severe course of COVID-19 is typical for children from risk groups. Newborns and young children, congenital malformations and concomitant diseases, primarily accompanied by immunodeficiency states of various etiologies (oncological and autoimmune diseases, diabetes mellitus) are the risk factors for the development of severe forms of coronavirus infection. The article presents two clinical cases of COVID-19 in children with acute lymphoblastic leukemia. It is shown that children with concomitant oncohematological pathology often have both mild and severe forms of coronavirus infection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>COVID-19</kwd><kwd>острый лимфобластный лейкоз</kwd><kwd>синдром Дауна</kwd><kwd>тоцилизумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>COVID-19</kwd><kwd>acute lymphoblastic leukemia</kwd><kwd>Down syndrome</kwd><kwd>tocilizumab</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">Намазова-Баранова Л.С., Мурашкин Н.Н., Иванов РА.
