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.
周四，漢諾威獸醫大學在《BMC Infectious Diseases》上發表了初步研究結果，他們從德國武裝部隊挑了8條狗，僅僅經過5天的訓練，就能嗅檢出人類中的感染者。他們嗅了1,000多人的唾液，包括健康的人和感染者，診斷準確率高達94%。
"We think this works because metabolic processes in the body of a disease patient are 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.
周四，Maren Von Köckritz-Blickwede教授在上傳到YouTube的一段視頻中針對這項研究說：“我們認為這種方法可行，因為病人體內的代謝過程發生了徹底改變，我們覺得狗能嗅到病人體內代謝變化的特殊味道。”
Dr. Holger Volk, another professor from the university, said that dogs have a sense of smell that is 1,000 times better than humans, so their potential within the medical field is huge.
"We know for a very long time that dogs have been used in a lot of walks of life, but for medical detection, it's a novel at the end of the day," Volk said. "People have not really realized the potential a dog could have to detect diseased from non-diseased patients."
