“However our findings counsel that SARS-CoV-2 an infection of the olfactory epithelium results in irritation, which in flip, damages the neurons, reduces the numbers of axons to be had to ship alerts to the mind and ends up in the olfactory bulb turning into dysfunctional,” she concluded

The find out about was once revealed on-line not too long ago in JAMA Neurology.

Your next step is to check tissues from sufferers who died of the Delta and Omicron variants of the coronavirus.

“We need to examine any axon injury and bulb disorder present in the ones tissues with what we noticed in sufferers who had the unique virus pressure,” Ho mentioned. “That approach, we’re going to have the ability to higher expect if Delta and Omicron are roughly prone to motive lack of scent.”
