A new observational study out of the U.K. has found that those who contract the Omicron variant of COVID-19 experience different symptoms that are usually less severe and last shorter than those who are infected with the Delta variant.
According to the ZOE COVID Study, which tracks self-recorded symptoms from participants using a smartphone app, those who contract Omicron are less likely to be admitted to hospital and lose their sense of smell than people with Delta.
The study also found that some of the “more debilitating symptoms” of COVID-19, including brain fog, eye burning, dizziness, fever and headaches, were also less prevalent in Omicron cases. Participants infected with Omicron were also less likely to report suffering from a cough, according to the study.
“The prevalence of symptoms that characterise an omicron infection differs from those of the Delta SARS-CoV-2 variant, apparently with less involvement of the lower respiratory tract and reduced probability of hospital admission,” the study’s authors wrote.
