Progressive Pulmonary Fibrosis After Non-Critical COVID-19: A Case Report.

BACKGROUND The COVID-19 global pandemic is ongoing, and despite vaccination efforts, SARS-CoV-2 continues to circulate worldwide. The spectrum of COVID-19 illness is broad, from asymptomatic infection to respiratory failure and acute respiratory distress syndrome (ARDS), and the long-term sequelae of infection are unclear. COVID-19-related pulmonary fibrosis has been previously described in the setting of critical illness and ARDS but has not been well described in cases requiring minimal supplemental oxygen.
