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，汉诺威兽医大学在《BMC Infectious Diseases》上发表了初步研究结果，他们从德国武装部队挑了8条犬，仅仅经过5天的训练，就能嗅检出人类中的感染者。他们嗅了1,000多人的唾液，包括健康的人和感染者，诊断准确率高达94%。
"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.
周四，Maren Von Köckritz-Blickwede教授在上传到YouTube的一段视频中针对这项研究说：“我们认为这种方法可行，因为病人体内的代谢过程发生了彻底改变，我们觉得狗能嗅到病人体内代谢变化的特殊味道。”
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."
