The second wave of desaturation in coronavirus disease 2019

Abstract

After a complete symptomatic recovery from coronavirus disease 2019 pneumonia, the second phase of desaturation is a new phenomenon that is being increasingly observed. Two possible mechanisms behind it can be a continued subclinical infection and lung fibrosis. We have presented a case with the former mechanism, who responded well to steroids.
