Skin rashes should be added to the NHS' official list of Covid-19 symptoms because one in 11 patients develop them, scientists say. 

King's College London academics drew on data from 20,000 Brits who either tested positive for Covid-19 or were heavily suspected of having the disease.

They found 9 per cent of infected Britons also suffered from skin rashes, while 8 per cent of people with other tell-tale symptoms also had the skin ailment.
