Abstract

Recently, many of the studies have illustrated that the new pandemic SARS-CoV-2 can affect Central Nervous System through the olfactory bulb. In addition to investigating anosmia or hyposmia induced by this virus, a quantitative analysis was needed to clarify the taste and smell disorder of the new coronavirus. The four basic taste quality with five concentrations for sweet, sour, bitter, and salty were administered to 75 subjects divided into three groups: COVID-19 patients with taste disorder, COVID-19 patients without taste disorder, and control group. The results indicated the increment of sweet (2.68 +/- 0.14), sour (3.34 +/- 0.12) and bitter (3.39 +/- 0.2) thresholds in COVID-19 patients with taste disorder in comparison with patients without taste disorder that the threshold were: 2 +/- 0.16, 2.11 +/- 0.2 and 2.55 +/- 0.5 for sweet, sour, and bitter respectively. On the other hand, the patients inversely showed a significant decrease in the salty taste threshold (0.51 +/- 0.03) compared to COVID-19 positive control groups (1.11 +/- 0.11). Additionally, despite taste disorder in almost all of the patients with smell deficiency, only 30 of cases with taste disorder reported smell deficiency. It may be concluded that some of the taste disorders in patients with COVID-19 disorder could be associated with taste receptors dysfunction or the spread of infection to the (c) 2021 The Authors.
