Sniffer dogs are more effective than rapid tests at detecting cases of Covid-19 and could soon be deployed at airports, according to a major British study.
Researchers found coronavirus has a ‘distinctive odour’ that means specially-trained medical detection dogs can identify infected people, even those without symptoms.
Astonishingly, the dogs are able to detect up to 94 per cent per cent of cases – making them significantly more accurate than rapid lateral flow tests.
The authors said their findings had ‘exceeded all expectations’ and that dogs could be used at workplaces, theatres and stadiums to help Britain get back to normal.
