Lung damage may persist long after COVID-19 pneumonia clears: study

Long-term radiological follow-up may be warranted, researchers say

CT scans show that patients who have recovered from COVID-19 pneumonia often have lingering pulmonary damage up to 12 months later, according to a new study.

Austrian clinicians say their findings, based on chest CT from adults with SARS-CoV-2 infection in the first year of the pandemic, may even represent permanent lung damage.
