Taste Changes (Dysgeusia) in COVID-19: A systematic review and metaanalysis

Abstract

The coronavirus disease – 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus -2 (SARS-CoV-2), originated in China and rapidly spread across the world, causing a pandemic.1 The wellrecognized symptoms of COVID-19 include fever, cough, dyspnea, sputum production, myalgia, arthralgia, headache, diarrhea, nausea/vomiting, and sore throat. It appears that a subset of COVID-19 patients also develops other symptoms such as ageusia/dysgeusia.2 We performed a systematic review of the available literature to assess the presence of ageusia/dysgeusia among COVID-19 patients.
