This paper reviews publications covering the delayed clinical and functional manifestations of SARS-CoV2 among athletes competing at national and international levels; we describe the prevalence of multiorgan failure associated with protracted COVID as registered in sportsmen and people not going in for sports. The review reports the results of a retrospective analysis of data yielded from clinical, instrumental and laboratory tests undertaken by the Russian national team athletes that had COVID-19. We highlight the most informative indicators that reflect the condition of sportsmen with protracted coronavirus infection course, define the approaches making resumption of active training safe and compile the list of the most significant criteria supporting admission to such training and competitions. Lastly, the paper presents the parameters subject to inclusion in the prognostic model (binary logistic regression) describing the dynamics of residual multiorgan failure in athletes, including minors, who have had COVID-19 or viral pneumonia of a different etiology.

Background. This review article surveys literature data on the methods of timely diagnosis and treatment of congenital cytomegalovirus infection (CMVI) in newborn infants. In recent years CMVI has become a subject of numerous global-scale studies. Such increased interest in CMVI is due to the fact that the consequences of congenital CMVI have a social impact. Description of clinical case. A clinical case of congenital manifest cytomegalovirus infection is described. The infant was diagnosed with CMVI on the 10th day of life. Complex therapy was prescribed in accordance with the protocol of management of congenital CMVI which led to positive dynamics. Conclusion. By today, an algorithm for detection and treatment of CMVI which brings positive results has been worked out. However, it is essential to keep in mind the long-term sequelae of CMVI and devote close attention to dispensary follow-up of such patients.
