Omicron and Delta variants of Covid differ with the symptoms they present, a new study has found.
People who have Omicron are more likely to have a sore throat and less likely to lose their smell compared to Delta, the study says.
According to the research, the biggest difference was in the loss of sense of smell, which appeared in 52.7% of Delta cases, and showed up in less than 20% of Omicron cases.
