On the other hand, sensorineural disorders result from injury of neuronal structures, most often olfactory sensory neurons, or olfactory bulbs. But in many cases, COVID does produce certain telltale symptoms, such as these ones that involve the mouth. Chlorine dioxide and sodium chlorite are highly reactive disinfectants used to treat public water systems. Viral infection of vascular pericytes (which express ACE-2) and/or immune-mediated vascular damage in both olfactory mucosa and olfactory bulb have also been hypothesized as a possible cause of olfactory impairment; indeed, a magnetic resonance microscopy study found evidence of microvascular injury in the olfactory bulbs of COVID-19 patients [27].

Though the risk of transmission of SARS-CoV-2 via surfaces is very low, simple washing with soap and water reduces this risk as will washing with cleaners containing chlorine. Although mouthwash affects the virus in the mouth and throat, it does not affect the virus in other primary spots such as the nasal passages, which may reinfect the throat. Chlorine is added to pool water to disinfect it. The amount of virus in patient saliva was positively correlated with taste and smell changes, according to the study. In samples collected at NIH from COVID-19 patients who had died, SARS-CoV-2 RNA was present in just over half of the salivary glands examined. It's been a long day, your stomach's rumbling and you've just tucked into your favourite Jamaican dish: you wait for that kick, but nothing, no taste whatsoever. An exceedingly dry mouth has also been reported as a COVID symptom, according to doctors; in fact, it's the most common oral-related COVID sign. Dentists currently use antimicrobial mouthwashes to reduce the number of microorganisms in liquid particles that may escape a persons mouth during procedures. Olfactory disorders could be distinguished into conductive and sensorineural [13]. Market data provided by Factset. Chlorine . Market data provided by Factset. Increasingly though, those who have recovered subsequently develop . One study found that 43 percent of people who tested positive for COVID had a dry mouth.
