Taste Changes (Dysgeusia) in COVID-19: A Systematic Review and Meta-analysis

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 well-recognized 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 patients with COVID-19 also develop other symptoms, such as ageusia/dysgeusia.2 We performed a systematic review of the available literature to assess the presence of ageusia/ dysgeusia among patients with COVID-19.
