Preliminary evidence does not support a primary role for direct infection of olfactory sensory neurons and taste buds in causing STD, suggesting that the loss of function of such neuronal structures may rather be a consequence of the infection of non-neuronal cells in the olfactory epithelium, oral mucosa, and possibly the olfactory bulb. Zhang A.J., AC-Y Lee, Chu H., et al. This will help slow the spread of the virus from people who do not know that they have contracted it, including those who are asymptomatic. However, the possible occurrence of other mechanisms leading to chemosensory dysfunction has also been hypothesized, and contrasting data have been reported regarding the direct infection of sensory neurons by SARS-CoV-2. Olfactory cleft obstruction and possibly direct infection of neuronal cells may also occur. Theoretically, SARS-CoV-2 infection in the mouth could cause changes in saliva production or quality, contributing to symptoms of taste loss, he said.

These features suggest that anosmia could possibly be the consequence of a localized impairment of airflow conduction or of a sensorineural damage. STD are usually reported within three days from the beginning of other COVID-19 manifestations [6,38] and have presented as the first symptoms in up to one quarter of the cases [39]. A recent, prospective diagnostic study which evaluated olfactory function in a large cohort of patients prior to COVID-19 testing confirmed these findings, reporting similar values of sensitivity and specificity [42]. Study shows how SARS-CoV-2 infects cells in mouth, possibly leading to Byrd and his co-author Dr. Blake Warner, an assistant clinical investigator in the Salivary Disorders Unit at the National Institute of Dental and Craniofacial Research, a branch of the U.S. National Institutes of Health, worked with an organization called theHuman Cell Atlasto organize and refine the data.

The gustatory cues, however, are combined with the sensations provided by retronasal olfaction to give rise to flavors [11]. But while many have regained their senses, for others it has turned into a phenomenon called . Munster V.J., Feldmann F., Williamson B.N., et al.
