During the period of accumulation of scientific data on the pathology of COVID-19 caused by SARS-CoV-2 virus, it was considered that coronavirus is the most dangerous for elderly people, and in young people the disease occurs mainly in mild form. Later on, these perceptions changed. WHO experts, despite their initial recommendations, already recognized the danger of COVID-19 for all ages. Objective. To evaluate the pathology structure in young patients aged 18-30 years who were hospitalized with the diagnosis of COVID-19 in a converted speedy hospital in Moscow in the period from April to June 2020. Material and methods. The data of 228 patients (156 men and 72 women) aged 18-30 years (average age 22.8±3.1 years) admitted to the hospital for diagnostics and treatment in the period from 10.04.20 to 22.06.20 with ICD-10 diagnoses were analyzed retrospectively: B.34.2. Coronavirus infection unspecified; U07.1. COVID-19, the virus is identified (confirmed by laboratory testing, regardless of the severity of clinical signs or symptoms); U07.2. COVID-19, the virus is not identified (COVID-19 is diagnosed clinically or epidemiologically, but laboratory tests are inconclusive or unavailable; J12.9. Extra-hospital pneumonia. Results. In more than 1/3 of patients in the age group 18-30 years COVID-19 with pneumonia developed without a pre-morbid background. The percentage of patients with COVID-19 with chronic upper respiratory tract, lung and pathology with immune regulation disorders was 10-19%, which requires the identification of such patients in the group of high risk of disease. Conclusions. Without severe concomitant diseases, including oncohematological and neurological forms of pathology, COVID- 19 in patients of young age in hospital care and treatment most often does not lead to death.
