Researchers at the University of Veterinary University of Hannover, Germany have found that dogs are capable of sniffing coronoviruses that cause COVID-19 with surprising accuracy.
During the tests, he found that eight dogs from the German Army could correctly identify the presence of coronovirus 94 percent of the time after just one week of training, Bloomberg Report.
“We think it works because the metabolic process in the body of a diseased patient completely changes,” said Marn von Koacritz-Blakeweed, a university professor, in a video statement posted by the university on YouTube. “We think dogs are capable of detecting a specific odor produced by the metabolic process”.
Despite dogs being used to sniff out a variety of conflicting substances and even explosives at airports and other places, “people have not really realized that dogs have been exposed to diseases from non-diseased patients.” May have to find out, ”argues Holger Volk, head of the small animal clinic at the University of Veterinary Medicine Hannover University.
The researchers suggested that the dog’s sniffing method could be employed in “public areas such as airports, sporting events, borders or other mass celebrations”, according to the video’s caption – but only in addition to existing laboratory testing.
The COVID-19 samples were completely random, so neither dog handlers nor researchers knew which samples were positive and which were not. In other words, the researchers guarded against the “cleaver goose” effect, in which animals appear to be solving complex problems, but are actually taking cues from their human handlers.
