Post COVID Interstitial Lung Abnormalities-Incidence and Management.

The available evidence suggests that up to 30% of patients have ILAs following COVID-19 hospitalization. The radiographic abnormalities improve or resolve in a majority of these patients. However, estimates suggest that up to one-third of these patients have irreversible fibrotic features. Clinical trials of the impact of anti-fibrotic agents are ongoing. As there continue to be thousands of COVID-19 hospitalizations in the USA each week, the management of post-COVID ILAs will become a common problem for the pulmonary practitioner.
