One third of patients hospitalised with severe COVID-19 still have lung changes after a year

A new study has shown that most patients discharged from hospital after experiencing severe COVID-19 infection appear to return to full health, although up to a third do still have evidence of effects upon the lungs one year on.

COVID-19 has infected millions of people worldwide. People are most commonly hospitalised for COVID-19 infection when it affects the lungs – termed COVID-19 pneumonia. Whilst significant progress has been made in understanding and treating acute COVID-19 pneumonia, very little is understood about how long it takes for patients to fully recover and whether changes within the lungs persist.

In this new study, published in The Lancet Respiratory Medicine, researchers from the University of Southampton worked with collaborators in Wuhan, China, to investigate the natural history of recovery from severe COVID-19 pneumonia up to one year after hospitalisation.
