Enigma of categorizing COVID-19-related lung parenchymal diseases and management experience with follow-up outcomes in Qatar: a case series

Abstract

Coronavirus disease 2019 (COVID-19) has become one of the worst global pandemics in recent history. Post-COVID-19 interstitial lung disease is a significant concern in COVID-19 survivors. It is a disabling clinical condition for patients and a burden on the healthcare system. With time and subsequent waves of COVID-19 globally, the post-COVID-19 sequelae of lung diseases can be debilitating. We report cases of three patients with persistent hypoxia post-COVID-19, raising concerns for interstitial lung disease in Qatar. In this report, we shared our experience of the patient's clinical course, complications, and outcomes with post-COVID-19 sequelae of lung parenchymal disease. Patients were followed up during and after treatment until recovery or discharge from the hospital.
