SEPULVEDA C, Valeria; WAISSBLUTH A, Sofía  y  GONZALEZ G, Claudia. Anosmia and coronavirus disease 2019 (COVID-19): ¿What should we know?. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2020, vol.80, n.2, pp.247-258. ISSN 0718-4816.

We are currently facing a global pandemic of great impact, as a result of the rapid spread of a new coronavirus, SARS-CoV-2, which causes coronavirus disease (COVID-19). We have yet to understand the pathophysiology of this disease, as well as the variety of signs and symptoms it can cause. The scientific and medical communities are constantly publishing their observations on this subject, a dynamic process with a wealth of information. An exhaustive review of the literature on smell and taste alterations in patients with COVID-19 was carried out. A significant variability was observed in the incidence of hyposmia/anosmia, from 5.1% to 85.7%, and of taste alterations ranging from 5.6% to 88.8%. This is due to the fact that most of the studies were mainly retrospective, and several occupied surveys without objective evaluation of smell or taste, limiting to establish clearly the incidence of these alterations. It was observed that alterations of smell and taste are in general frequent in these patients, and that they present a good prognosis.

Palabras clave : Smell; taste; anosmia; COVID-19; SARS-CoV-2.
