After just a few days of training, dogs in Germany proved capable of
identifying people infected with COVID-19, according to researchers. The dogs, part of a study by a veterinary university in Germany, were able to sniff out the coronavirus with stunning accuracy.
According to the pilot
study published Thursday in BMC Infectious Diseases by the
University Veterinary Medicine Hannover, eight dogs from Germany's armed forces trained for just five days before they could identify the virus in humans. They sniffed the saliva of more than 1,000 people, both healthy and infected, identifying the
coronavirus with a 94% success rate.
"We think this works because metabolic processes in the body of a diseased patient is completely changed, and we think that the dogs are able to detect a specific smell of the metabolic changes that occur in those patients," Professor Dr. Maren Von Köckritz-Blickwede said in a
YouTube video on the study Thursday.
