Conclusion:
The second wave of desaturation after resolution of symptoms
post-COVID-19 treatment is a rare phenomenon. It can be secondary to an
ongoing subclinical infection or due to fibrosis. The role of steroids
is not studied in this scenario. Our patient had a dramatic response to
steroids indicating a possible role in reducing the post infection
inflammation. Larger studies are needed to investigate the management of
post-COVID-19 desaturation.
