Abstract
BACKGROUND: Medical publications about anosmia with COVID-19 are scarce. We aimed to describe the prevalence and features of anosmia in COVID-19 patients.
METHODS: We retrospectively included COVID-19 patients with anosmia between March 1 and March 17, 2020. We used SARS-CoV-2 real time PCR in respiratory samples to confirm the cases.
RESULTS: Fifty-four of 114 patients (47%) with confirmed COVID-19 reported anosmia. Mean age of the 54 patients was 47 (±16) years; 67% were females and 37% were hospitalized. The median Charlson comorbidity index was 0.70 (±1.6 [0-7]). Forty-six patients (85%) had dysgeusia and 28% presented with pneumonia. Anosmia began 4.4 (±1.9 [1-8]) days after infection onset. The mean duration of anosmia was 8.9 (±6.3 [1-21]) days and 98% of patients recovered within 28 days.
CONCLUSIONS: Anosmia was present in half of our European COVID-19 patients and was often associated with dysgeusia.
