Abstract
in English, Spanish

Some reports have been recently published on olfactory loss in people with severe COVID-19. It is suggested to take into consideration the recommendations of the American Academy of Otolaryngology and the British Association of Otorhinolaryngology to include olfactory loss as an early clinical symptom of COVID-19 and consider sudden olfactory loss, as a high index of suspicion of SARS-CoV-2 infection. It can be established that the majority of patients with olfactory loss due to COVID-19, present hyposmia and not anosmia. Patients with olfactory loss, who had SARS-CoV-2 infection, should be classified as loss secondary to viral infection.

Se sugiere tomar en consideración las recomendaciones de la American Academy of Otolaryngology y la British Association of Otorhinolaryngology para agregar la pérdida olfatoria como síntoma clínico temprano de COVID-19, y considerar la pérdida súbita olfatoria como alto índice de sospecha de infección por SARS-CoV-2. Se puede establecer que la mayoría de los pacientes con pérdida olfatoria por COVID-19 presentan hiposmia y no anosmia. Los pacientes con pérdida olfatoria que cursaron con infección por SARS-CoV-2 deben ser clasificados como pérdida secundaria a infección viral.
