Covid expert Tim Spector has issued a warning as cases of the virus are on the rise again.
In a video, the Professor, who founded the ZOE Covid Study app, said now around one in 44 people in the UK has covid. There are more than 112,000 new cases each day.
Prof Spector said BA.5 is now the dominant variant. The most common symptoms of this strain are a sore throat - with around two thirds of people infected experiencing this - as well as headaches, a blocked or runny nose, and a dry cough.
