[Clinical and laboratory parameters and pathomorphological features of the lungs in patients who have had COVID-19 viral pneumonia].

Post-Covid syndrome is characterized by general somatic manifestations, changes in the psycho-emotional sphere, cognitive disorders, disorders of the cardiovascular, respiratory systems and excretory function. However, there is little information in the literature about the mechanisms of thanatogenesis in patients who have had COVID-19.
