COVID-19 Omicron Variant Much Less Likely to Result in Smell Loss
Olfactory research community hardest hit
Did you spend hundreds of hours writing an NIH grant on the topic?
Well, you lose.
New study in Lancet (N = 63,002) finds
loss of smell was less common in participants infected during omicron prevalence than during delta prevalence (16.7% vs 52.7%, odds ratio [OR] 0.17; 95% CI 0.16–0.19, p<0.001).
And there’s this:
loss of sense of smell, a pathognomonic feature of earlier waves of SARS-CoV-2 infection, now present in less than 20% of cases.
Great news for chefs, vintners, brew masters, perfumers, weed farmers and all of us who love to smell their creations.
