Anosmia and dysgeusia associated with SARS-CoV-2 infection: an age-matched case–control study

Abstract

We found a strong association between olfactory and gustatory symptoms and SARS-CoV-2 positivity. These symptoms should be considered as common and distinctive features of SARS-CoV-2 infection and should serve as an indication for testing and possible retesting of people whose first test result is negative.
