To begin with, it was just anecdotal reports. Ear, nose and throat specialists from around the world were sharing their experiences on online message boards – they were all seeing a spike in patients experiencing anosmia, a loss of smell. The link with coronavirus was brought to public attention by specialists in the UK in late March, and since then health organisations have gradually added anosmia to the list of symptoms for Covid-19. According to a recent study, about two-thirds of people with Covid-19 experience a sudden loss in smell or taste.
