Scientists found traces of COVID-19 in the organs almost three years after recovery. The study was carried out by experts from the University of Sechenov. As the university's press service reported to TASS, traces of the coronavirus were found in the lungs of one of the patients 35 months after the illness. Tissues obtained during surgeries and autopsies were examined. Scientists say the evidence suggests that the long-term persistence of viral components may be one of the causes of post-Covid syndrome, along with autoimmune reactions.
