Summary/Key points
- The prevalence of subjective OD and GD were higher in mild compared with moderate and severe-to-critical COVID-19 patients. The psychophysical olfactory evaluations were better in moderate and severe-to-critical patients, which may indicate a higher proportion of objective OD in individuals with mild COVID-19.
-Females had a higher prevalence of subjective OD and GD compared with males.
-Diabetes was associated with a higher risk to develop GD.
- The development of OD and GD could be predictive factors of the severity of the COVID-19. Gender (female) was identified as epidemiological factor associated with the development of both OD and GD.
