Abstract
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from Wuhan, China in December 2019 leads to the present coronavirus disease 2019 (COVID-19) pandemic. The various symptoms identified for COVID-19 are fever, dry cough, sore throat, dyspnea, fatigue, myalgia, and headache. Olfactory and gustatory dysfunctions are emerging as a new symptom more in the European patients. Taste disturbances are common in various oral and systemic diseases. Varying severity and onset of taste disturbances are reported in COVID-19 positive patients in this pandemic. But a sudden onset of taste disturbances without an established and recognized cause should raise suspicion of COVID-19. This article will analyze the various studies focusing on taste disturbances as a reliable early symptom for COVID-19 screening.
