To get a runny or blocked noseand cannot detect sweet or bitter tastes, a new study published on August 19 has discovered. The study is the first to evaluate how people with COVID-19 smell and taste disorders differ from people with other causes of upper respiratory tract infections, according to the researchers, including those in the University of East Anglia (UEA) in the united kingdom.

The researchers hope their work might help develop odor and taste evaluations for fast COVID-19 screening - in primary care and emergency sections.

The findings, released in the journal Rhinology, lend weight to the theory that COVID-19 interrupts the brain and central nervous system.

"The reduction of smell and taste is a prominent symptom of COVID-19, but it's also a frequent symptom of using a terrible cold," said lead researcher Carl Philpott, a professor at UEA's Norwich Medical School.

"We wanted to learn exactly what differentiates COVID -19 odor loss together with the kind of odor loss you might have using a cold and blocked-up nose," Philpott said.

"We wanted to see whether their smell and taste test scores might help discriminate between COVID-19 sufferers and those with a heavy cold," Philpott said.

The researchers noticed COVID-19 behaves differently to other respiratory ailments, such as by inducing the body's immune system to over-react, known as a cytokine storm, and by changing the nervous system.

The investigators said it was this reduction of true taste which seemed to be found from the COVID-19 patients in comparison to those with a cold.

"This is extremely exciting because it usually means that odor and taste tests could be employed to discriminate between COVID-19 patients and individuals with a normal cold or flu," Philpott said.

"Although such evaluations could not replace formal analytical tools such as throat swabs, they can provide an alternative when traditional tests are not available or if quick screening is required -- particularly at the level of care, in emergency departments or at airports," he added.

The analysis also indicates that there are completely different things going on as it pertains to smell and flavor loss for COVID-19 sufferers, compared to people who have a terrible cold, the researchers said.
