Olfactory and rhinological evaluations in SARS-CoV-2 patients complaining of olfactory loss.

Since December 2019, a novel coronavirus SARS-CoV-2 (Covid-19) outbreak emerged in China and spread rapidly in several countries. As of April 5, 2020, 1.218.474 cases were confirmed with 65.884 deaths worldwide (1). The clinical manifestations of Covid-19 range from asymptomatic carrier status to severe pneumonia. In a study of 7,736 Covid-19 patients in China, of all the clinical symptoms, hyposmia was not reported in any patient(2). Anyway, it is now clear that olfactory dysfunction may also be present in these patients(3) as the only or prevalent manifestation(4).
