Abstract

Based on observations described in our letter, we can draw the following conclusions: (1) anosmia must imperatively be added to the list of specific symptoms of COVID-19 infection, (2) anosmia can serve as a free and specific diagnostic tool for developing countries currently affected by the pandemic, (3) the mechanisms of COVID-19 anosmia seem not to directly involve nasal obstruction but rather seem to be related to damage the olfactory neuroepithelium.

Keywords: COVID-19; anosmia; diagnostic; neuroepithelium.
