OBJECTIVE The aim: To analyse the structure of sensory impairments, associated with COVID-19. To identify terms of recovery periods depending on severity of disease, age and gender of the patients. PATIENTS AND METHODS Materials and methods: Within two weeks, 2225 patients with confirmed COVID-19 completed a questionnaire, created by Google Forms. General complaints, peculiarities of sensory impairments and recovery time were specified. After exclusion criteria application, data of 2108 patients were analyzed by R Statistics Package, Student's t-test, Wilcoxon rank-sum test, Fisher's exact test, Spearman's rank test. RESULTS Results: Among patients enrolled (973 males and 1135 females, mean age 28.6±0.18) the most frequent were olfactory (91.32%) and gustatory (66.03%) dysfunctions. Olfactory manifestations were usually accompanied by gustatory disorders (73.72%). Average duration of olfactory dysfunction was 15.46±0.45 days, gustatory - 11.3±0.33, hearing - 4.3±0.16, and visual - 6.53±0.23 days. It was found a correlation between duration of olfactory and gustatory impairments (r=0.65; p < 0.001), hearing and visual disorders (r=0.49; p < 0.05). CONCLUSION Conclusions: Olfactory and gustatory disorders are prevalent symptoms in Ukrainian population. 7.87% of respondents who had impairment of all four sensory functions had the longest recovery time. Duration of sensory impairments did not depend on age, type of treatment and severity of disease, which rises the question about the neurogenic pathway of virus.
