ANALYSIS OF COVID-19 IMPACT ON THE STATE OF HEALTH AND CARDIOVASCULAR FUNCTION OF CHILDREN 7-9 YEARS OLD

Abstract

Influenza and acute respiratory viral infections pose significant challenges in paediatrics, given their high prevalence among children and the potential for severe and complicated cases, particularly in young age groups. Over the past 20 years, there have been three coronavirus epidemics that have caused a substantial number of severe cases, high mortality rates, and global transmission. This review aims to provide a comparative analysis of clinical and epidemiological features of coronavirus infections in children, drawing from the examples of SARS and MERS, and offers essential approaches and recommendations for the diagnosis and treatment of COVID-19. The review covers the etiology, epidemiology, laboratory diagnosis, clinical presentation, and treatment of severe acute respiratory syndrome. It also provides a brief historical overview of the epidemiology, diagnosis, and treatment of this disease. Unlike other respiratory viral infections, COVID-19 can result in persistent symptoms following the acute phase, known as post-infection COVID-19 syndrome, which can last for weeks or even months. The long-term effects of COVID-19 in children are not yet fully understood, and further research is needed to explore its true prevalence, pathogenesis, and lasting impacts. The management of paediatric post-infection COVID-19 syndrome requires a multidisciplinary approach, international collaboration, and consensus to ensure early detection and effective treatment in children. The article presents current scientific insights into the factors contributing to the development of a prolonged post-COVID period, including chronic systemic inflammation, endothelial dysfunction, coagulation disorders, autoimmune reactions, and other immunological changes. The COVID-19 outbreak serves as a reminder of the ongoing threat posed by infectious diseases caused by pathogenic viruses, highlighting the need for global cooperation and preparedness to effectively mitigate their spread.
