Compared to rates of smell and taste loss during the early phase of the pandemic in 2020 before variants were identified, chances of smell and taste loss were just 17% for omicron, 44% for delta and 50% for the alpha variant. Researchers used a national database of over 3.5 million cases of patients who tested positive for COVID-19 since the onset of the pandemic.

(May 10, 2022) - People infected with the COVID-19 omicron variant are significantly less likely to develop smell and taste loss compared to those infected by delta and earlier COVID-19 variants, according to results published this month by Virginia Commonwealth University researchers in the journal Otolaryngology - Head and Neck Surgery.
