OBJECTIVE To determine the incidence and prognosis of olfactory,gustatory and auditory dysfunctions related to the COVID-19 Omicron strain infection.METHODS A cross-sectional investigation was performed through online questionnaires.Data of patients with Omicron strain infection from December 24th,2022 to January 2nd,2023 were collected.The visual analogue scale(VAS)was used to evaluate the self-reported olfactory,gustatory and auditory functions of patients.RESULTS A total of 869 valid questionnaires were obtained.The incidence of otolaryngology-related symptoms associated with omicron strain infection was 96.8%.The incidence of olfactory,gustatory and auditory dysfunction was 44.4%,44.2%and 10.7%,respectively.There were statistically significant differences(P<0.001)in VAS scores for olfactory,gustatory,and auditory impairments between all surveyed individuals before and after infection,as well as in the corresponding VAS scores for those who experienced these impairments.The median duration of olfactory,gustatory and auditory dysfunction were 5,4 and 3 days,respectively.CONCLUSION The incidence of olfactory,gustatory,and auditory impairments is high after Omicron infection,with most cases experiencing rapid spontaneous improvement.For the long-term symptoms,the otolaryngology doctors are responsible for exploring and developing effective intervention measures.
