Headache and runny nose linked to Delta variant
A headache, sore throat and runny nose are now the most commonly reported symptoms linked to Covid infection in the UK, researchers say.
Prof Tim Spector, who runs the Zoe Covid Symptom study, says catching the Delta variant can feel "more like a bad cold" for younger people.
But Prof Spector says these are now less common, based on the data the Zoe team has been receiving from thousands of people who have logged their symptoms on an app.
"Since the start of May, we have been looking at the top symptoms in the app users - and they are not the same as they were," he says.
The change appears linked to the rise in the Delta variant, first identified in India and now accounting for 90% of Covid cases in the UK.
"People might think they've just got some sort of seasonal cold and they still go out to parties and they might spread around to six other people.
Similarly, the Imperial College London React study of more than a million people in England - when the Alpha or UK variant was dominant - found a wide range of additional symptoms linked to Covid.
