Surprisingly, 9 of 16 (56%) of our cohort were serologically diagnosed with COVID-19-related POD. Other causes of POD included eosinophilic sinusitis (1), non-SARS-CoV-2 post-viral (2), and idiopathic (4). COVID-19-related POD patients were more likely to expwrience gustatory dysfunction than other miscellaneous PODs (6 of 9, 67% vs. 2 of 7, 29%). Despite not reaching statistical significance due to the limited sample size of the study, the degree of POD assessed by all three presented methods showed a trend toward increased severity for COVID-19-related disease (Table). When the patterns of impairment in OE odor discrimination were evaluated odorant by odorant, patients with COVID-19 were more frequently non-recognizable of menthol (4 of 8, 50% vs. 2 of 7, 29%).
