Olfactory Sensitivity in Covid 19 Infection Recovered Subjects.

Sense of smell is a vital perception in mammals. Temporary loss of smell is the main neurological symptom and one of the earliest and most commonly reported indicators of COVID-19. A observational hospital based analytical study carried out at a tertiary care centre for a period of 22 months from January 2021 to October 2022. All the patients were subjected to sniffin stick test and all the data were noted, tabulated and compared to know the correlation of olfactory sensitivity to different parameters. Males were affected with hyposmia slightly more than females. There was not much difference in the olfactory sensitivity in various phases of uterine cycle. Olfactory sensitivity had a negative correlation with serum oestrogen and serum progesterone levels, which was significant. Mean olfactory sensitivity of males for different odours were slightly higher than females. BMI has a negative correlation with olfactory sensitivity in males as well as females, which was significant.
