Studies from the University of Helsinki Faculty of Veterinary Medicine have shown that trained dogs are almost 100 percent. accurately recognize the smell of COVID-19. Finavia, which runs the Finnish airport, said that a sensitive dog’s sense of smell recognizes the virus from just 10 to 100 molecules of the virus, while the laboratory equipment needs up to 18 million.
“The project, which begins on September 22, is unique and the first of its kind in the world. No airport has done it before on a large scale. This could be another step forward in the fight against COVID-19,” he said Ulla Lettijeff, director of Helsinki Airport.
It is true that passengers do not have direct contact with the animal, a special cloth with which they scrape their skin, sniffed by dogs, which immediately inform whether a person is a carrier of a coronavirus. If a positive test result is found, the passenger is sent to the airport health information center.
The dogs were developed by the Finnish agency Wise Nose, and most dogs have had experience detecting odors before. The duration of the dogs’ training depended on their experience. One of the dogs, an eight-year-old mongrel, learned to recognize the scent in just 7 minutes.
