Pulmonary Fibrosis as Sequelae of Covid-19 Pneumonia

Abstract

The extent, severity and impact of long-term respiratory complications of covid-19 is not yet fully explored, but early data shows that many survivors persistent respiratory symptoms months after their initial illness. Potential post-covid-19 problems include chronic cough, fibrotic lung disease, bronchiectasis and pulmonary vascular disease.1 The evidence for these sequelae is derived from our current experience of covid-19 along with extrapolation of past data from SARS-CoV 1 outbreak and patients with ARDS due aetiology other than covid.2 It is reported that approximately 30% of people with SARS or MERS had long- term respiratory abnormalities after their acute illness.
