Study uncovers two phases of infection in patients with severe COVID-19 pneumonia

(Massachusetts General Hospital) To analyze SARS-CoV-2 at the tissue level, scientists examined lung specimens from 24 patients who succumbed to COVID-19. The analyses revealed two phases of infection in the patients: an early phase defined by high levels of virus in the lungs, and a later phase in which the virus is no longer present, but the damage to the lungs is too severe for recovery.
