Our study aims to analyze the presence of olfactory and gustatory dysfunctions Olfactory and gustatory dysfunctions (OGDs) in patients with COVID-19 and to assess their onset and recovery. Materials and Methods: The cross-sectional study was conducted in March 2021 retrospectively at Care Multispecialty Hospital, Vadodara. A total 301 patients were admitted, among those 280 qualify according to inclusion criteria and 3 patients denied to participate in the study. All patients presenting with laboratory-confirmed real-time reverse transcriptase polymerase chain reaction test for SARS-CoV-2 were included in the study.

Results: Two hundred and seventy-seven patients were included in this study. One hundred and fifty-three patients (55%) reported olfactory and gustatory disorders. Loss of taste and smell were more frequently reported in female patients (72.8%) than male patients (48%). Onset of these symptoms concomitant with other typical symptoms of COVID-19 is in 58.2% of cases. Recovery of symptoms in most patients was in 5–10 days and faster in younger patients.
