Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease had first appeared in December 2019 in Wuhan, China, and since then, it has emerged as a global threat to humanity. An early diagnosis and isolation are the most significant measures required to prevent its spread. Recent anecdotal evidence has suggested impairment of olfactory and gustatory sensations associated with corona virus disease (COVID-19). Angiotensin-converting enzyme-2 is an important aspect for the manifestations seen in this deadly viral disease. The associated olfactory and gustatory dysfunction can also lead to partial and/or complete loss of the ability to smell and taste in the early stages of disease onset. Evidence has also suggested that the presence of SARS-CoV-2 nucleic acid in human saliva makes it the carrier of the infectious viral disease and aids in its diagnosis. The present review focuses on the listed clinical manifestations in the form of olfactory and gustatory impairment in SARS-CoV-2 virus disease.
