Key Points

To compare COVID-19-related olfactory dysfunction with classical post-viral olfactory dysfunction.
Retrospective multicenter study
Analysis of clinical features
Comparison of pathophysiology
COVID-19-related olfactory dysfunction differs from post-viral olfactory dysfunction in clinical features
Pathophysiological differences exist between COVID-19 and post-viral cases
Differences in variants of COVID-19 correlate with biological differences in the virus.

Implication

Retrospective study compares clinical features and pathophysiology of olfactory dysfunction in COVID-19 and post-viral cases, highlighting variant differences.
