People with an Omicron infection are more likely to have a sore throat and are less likely to experience loss of smell, compared with Delta.
That’s one of the key findings to come out of the largest worldwide population studies into how the symptoms of Omicron compare with those of Delta.
For the study, published on the 7th April in The Lancet, researchers looked at symptoms of 62,002 vaccinated participants in the UK from the ZOE COVID Study App who tested positive between June 1 to November 27, 2021, when Delta was dominant, as well as from December 20, 2021–January 17, 2022, when Omicron was dominant.
The findings show that the duration of COVID-19 symptoms was significantly shorter (6.87 days versus 8.89 days), and participants were less likely to be hospitalised with the Omicron variant compared with the Delta variant.
