Association of chemosensory dysfunction and COVID‐19 in patients presenting with influenza‐like symptoms
Open accessAbstract
Background: Rapid spread of the severe acute respiratory syndrome‐coronavirus‐2 (SARS‐CoV‐2) and concern for viral transmission by ambulatory patients with minimal to no symptoms underline the importance of identifying early or subclinical symptoms of coronavirus disease 2019 (COVID‐19) infection. Two such candidate symptoms include anecdotally reported loss of smell and taste. Understanding the timing and association of smell/taste loss in COVID‐19 may help facilitate screening and early isolation of cases. Methods: A single‐institution, cross‐sectional study evaluating patient‐reported symptoms with a focus on smell and taste was conducted using an internet‐based platform on adult subjects who underwent testing for COVID‐19. Logistic regression was employed to identify symptoms associated with COVID‐19 positivity. Results: A total of 1480 patients with influenza‐like symptoms underwent COVID‐19 testing between March 3, 2020, and March 29, 2020. Our study captured 59 of 102 (58%) COVID‐19–positive patients and 203 of 1378 (15%) COVID‐19–negative patients. Smell and taste loss were reported in 68% (40/59) and 71% (42/59) of COVID‐19–positive subjects, respectively, compared to 16% (33/203) and 17% (35/203) of COVID‐19–negative patients ( p < 0.001). Smell and taste impairment were independently and strongly associated with COVID‐19 positivity (anosmia: adjusted odds ratio [aOR] 10.9; 95% CI, 5.08‐23.5; ageusia: aOR 10.2; 95% CI, 4.74‐22.1), whereas sore throat was associated with COVID‐19 negativity (aOR 0.23; 95% CI, 0.11‐0.50). Of patients who reported COVID‐19–associated loss of smell, 74% (28/38) reported resolution of anosmia with clinical resolution of illness. Conclusion: In ambulatory individuals with influenza‐like symptoms, chemosensory dysfunction was strongly associated with COVID‐19 infection and should be considered when screening symptoms. Most will recover chemosensory function within weeks, paralleling resolution of other disease‐related symptoms.

In the citing paper
“Any reasonable pathophysiological mechanism for COVID-19-associated anosmia must account for the high penetrance of smell disorders relative to endemic viruses (12, 91, 92), the apparent suddenness of smell loss that can precede the development of other symptoms (11, 13), and the transient nature of dysfunction in many patients (11, 17, 18); definitive identification of the disease mechanisms”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
