简要总结
200 participants should be included in the study. There will be three groups: 100 participants with a severe course of the disease 3 months ago, 50 asymptomatic carriers of coronavirus infection 3 months ago and 50 people who were in close contact with patients with confirmed coronavirus infection 3 months ago, but not sick and without antibodies to SARS-CoV-2.
The study consists of two visits. At the first visit, after signing the consent to participate in the study, a screening examination will be performed to assess the criteria for inclusion and exclusion in the study.
At the second visit, patients who meet the inclusion criteria and do not have exclusion criteria will undergo clinical and instrumental examination, and biological samples will be collected for laboratory testing.
The aim of the study is to determine the most significant clinical and laboratory markers of the severity of the outcomes in the period of convalescence of the new coronavirus infection COVID-19. Clinical and laboratory indicators, the number and severity of signs of postcovid syndrome as well as pathological changes in lung tissue according to CT data in the group with covid pneumonia and indicators of immune status, hemostasis, endothelial dysfunction, inflammation, metabolism will be assessed.
