More than 50% of previously hospitalized survivors of SARS-CoV-2 infection will have abnormality at CT, more commonly in those with more severe acute infection.
■ The most common abnormalities are ground-glass opacity, parenchymal or subpleural bands, reticular abnormality, evidence of fibrotic abnormality, and air trapping.
■ Precise radiologic description is important; the term fibrosis should be reserved for those with clear evidence of fibrosis (traction bronchiectasis or bronchiolectasis, honeycombing, or architectural distortion).
■ Comparison with acute-phase imaging is important to understand the temporal course of abnormality.
■ The long-term outcome of CT changes after COVID-19 and the impact on pulmonary function and quality of life are unknown.
Meanwhile ongoing proof that unvaxxed people died of Covid at 10X the rate of vaxxed people.
