A headache and runny nose - symptoms of the Delta variant
A headache, sore throat and runny nose are the most commonly reported symptoms linked to Delta variant of Covid infection in the UK, researchers say.
Data from the Zoe COVID Symptom Study, an app that allows people to track symptoms, shows COVID-19 symptoms in the United Kingdom may be changing as the delta variant spreads.
Top symptoms reported on the app include:
• Sore throat
• Runny nose
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 although they may not feel very ill, they could be contagious and put others at risk.
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.
Fever remains quite common but loss of smell no longer appears in the top 10 symptoms, Prof Spector commented to BBC.
