Trademark symptoms of seasonal flu could be mistaken for symptoms of Covid-19 if the individual tests positive for the virus, it is claimed.

More than eight in ten people who test positive for coronavirus show none of the main symptoms at the time they are tested, a major study by UCL previously revealed.

However, those who test positive when they have cold symptoms may mistake them as being a part of the virus – adding to fears that it is taking a new guise as fresh strains emerge.
