As the coronavirus pandemic rages on, so far more the 1.9 million people have been confirmed to have the killer bug. The two major symptoms of the illness are a new, persistent cough and a fever and those who have these are urged to stay home and self-isolate.
However some people who have the virus are asymptomatic, meaning they carry it but do not experience any symptoms. But it seems there might be a new way to detect whether you've been exposed to Covid-19, even without symptoms - and the answer could be in your feet.
Medical experts in Spain are currently investigating whether those who have the virus could be identified by small lesions on the feet.
