Dogs with a few days of training are capable of identifying people infected with the coronavirus, according to a study by a German veterinary university, Bloomberg reports.

Eight dogs from Germany’s armed forces were trained for only a week and were able to accurately identify the virus with a 94 per cent success rate, according to a pilot project led by the University of Veterinary Medicine Hannover.

Researchers challenged the dogs to sniff out Covid-19 in the saliva of more than 1,000 healthy and infected people.
