Conclusion
The prevalence of subjective and objective OD was higher in mild
COVID-19 patients compared with moderate and severe-to-critical
patients. Subjective GD and AD could be more prevalent in mild COVID-19
forms but future studies using objective taste measurements are needed
to confirm these findings. Age, gender and diabetes were identified as
favoring factors of development of OD, GD or AD while hypertension was
associated with a lower probability to develop OD.
