Post-COVID-19 pulmonary fibrosis: A case series and review of literature

The most common lung problem faced by a post-COVID patient is lung fibrosis. Clinical recovery is generally complete in mild-to-moderately severe COVID-19 cases but a small proportion of patients with severe disease may go on to develop lung fibrosis. Patient groups at the highest risk to develop lung fibrosis are the elderly, especially those requiring ICU stay and mechanical ventilation. No definitive therapy for managing this pulmonary fibrosis exists as of date, even though various options are being explored. This case series highlights three cases of post-COVID lung fibrosis and reviews the existing literature.
