Otolaryngologic Manifestation and Long-Term Outcome in Mild COVID-19: Experience from a Tertiary Care Centre in India

ABSTRACT: This study endeavours to comprehensively the study the spectrum of ENT manifestations in mild and asymptomatic COVID-19 and observe the natural course of anosmia and dysgeusia consequent to SARS-Cov-2 infection. A prospective cohort study was undertaken at a tertiary care centre in India on admitted patients with RT-PCR proven COVID-19. Patients were included provided the baseline National Early Warning Score (NEWS) was less than 4. Patients were screened for ENT manifestations using a questionnaire at baseline, 7 days, 14 days and 28 days. 225 patients were included in the study. Of these complete data at 4 weeks was available for 210. Out of 145 patients with mild COVID-19 (asymptomatic?=?80), ENT manifestations accounted for 66.2% of all symptoms. Smell and taste disturbance had an overall incidence of 20% and 45% of ENT manifestations. Temporal trends of the recovery rate of anosmia and dysgeusia were 53.6% and 66.7% at 2 weeks, respectively. Corresponding rates at 3 weeks were 89.29% and 86.7%, respectively. By the end of 4 weeks 96% of the patients had recovered completely. The incidence of anosmia and dysgeusia in this study parallels the rates reported from other Asian countries, albeit, lower than the rates quoted from the Western Hemisphere. We recommend structured reporting of all ENT manifestations especially smell and taste disturbances to accurately identify individuals infected with SARS-Cov-2.
