ABSTRACT
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.
