RESUMO
PURPOSE: Severe acute respiratory syndrome caused by COVID-19 has spread globally for the last few months. Healthcare workers (HCW) are overexposed and infection rates are higher than in the rest of the population. Strict clinical assessment is paramount to detect suspicious cases. In this context, olfactory or taste dysfunction (OTD) appears as an early and frequent symptom. Evaluating its presence in early stages plays an important role nowadays. METHODS: We performed a descriptive observational single-center study among 256 HCW at Hospital Universitario de Fuenlabrada affected by COVID-19 and confirmed using RT-PCR. A telephonic interview was performed, after obtaining oral informed consent. RESULTS: OTD was present in up to 70% of the cases as an early symptom, including mild-to-severe cases. The extent of these sensory deficits lasted an average of 11 days. In 26% of the patients, these sensory alterations persisted for over a month. CONCLUSION: OTD is reported as an early symptom among HCW with SARS-CoV-2 infection. Its strong association with test positivity is useful in the management of the infection and should be enough to indicate preventive isolation. We consider that OTD needs to be included in clinical screening questionnaires in HCW.
