Smell and Taste Loss Recovery Time in COVID-19 Patients and Disease Severity.

摘要: A significant proportion of people infected with SARS-CoV-2 report a new onset smell or taste loss. The duration the chemosensory impairment and predictive factors recovery are still unclear. We aimed to investigate prevalence, temporal course predictors in patients who suffered from varying disease severity. Consecutive adult diagnosed be via reverse-transcription–polymerase chain reaction (RT-PCR) at two coronavirus disease-2019 (COVID-19) Reference Hospitals were contacted complete survey reporting loss, severity, timing duration, nasal symptoms, smoking, allergic rhinitis, chronic rhinosinusitis, comorbidities COVID-19 In cross-sectional study, we 182 150 responded. Excluding critically ill patients, 38% reported gustatory 41% olfactory (74% severe/anosmia). Most (88%) recovered their sense by months (median: 11.5 days; IQR: 13.3). For 23%, loss lasted longer than month. There no differences prevalence between groups sexes (all p > 0.05). Moderate hyposmia resolved quicker more severe (p = 0.04). Smell highly prevalent COVID-19. recover fast, but nearly one out ten have not months.
