According to a new study from the German Veterinary University, dogs with only one week of training were able to identify individuals infected with novel coronavirus disease with a 94 percent success rate.
A study conducted by the University of Veterinary Medicine Hannover in collaboration with the German Armed Forces found that if properly trained, dogs were able to sniff the disease in the saliva of patients with COVID-19.
To conduct the study, the researchers trained eight dogs for a week, where they sniffed the saliva of more than 1,000 people who were either healthy or infected with the virus. Canine was successfully able to determine the difference between saliva samples from patients who tested positive for this disease and those who tested negative.
The authors of the study shared, “Within the randomized and automated 1012 sample presentations, dogs detected a positive, overall average rate of 94% with 792 true negatives, 33 false positives, and 30 false negative signs.”

“Dogs have a lot of brain power to explain smells. According to VCA Animal Hospitals, there are more than 100 million sensory receptor sites in the nasal cavity, compared to 6 million in people. “The area of the canine brain devoted to odor analysis is about 40 times larger than the comparable part. The human brain. In fact, it has been estimated that dogs can smell anywhere from 1,000 to 10,000 times better than people . “
He stated, “Unlike humans, dogs have an extra olfactory device that enhances their ability to smell. The organ acts as a secondary olfactory system specifically designed for chemical communication. “
But how do the canteen, especially the canteen, smell?
“We think it works because the metabolic process in a diseased patient’s body changes completely,” Maran von Kockeritz-Blickweed, a professor at the aforementioned university, said in a YouTube video about the study said. “We think dogs. Are able to detect a specific smell.”
Although further research is still needed, von Koacritz-Blickweed says the next step is to train dogs to distinguish COVID-19 samples from other diseases.

The authors of the study stated that the findings are preliminary and that more research needs to be done to help develop more reliable screening methods for COVID-19-infected patients.
The study also notes that the detection method may one day be used in public areas such as airports, sporting events, country borders or other mass celebrations. It can also serve as an alternative to, or as an alternative to, laboratory testing to help prevent further spread of the virus.
