The effects of severe COVID-19 on the lungs after one year

While short-term lung damage has been reported in patients hospitalized with pneumonia caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is little data on the more chronic sequelae of this condition. A new research paper summarizes data from patients seen one year from discharge.
