NBC晚间新闻 训练犬有望帮助探测新冠病毒

We all know the amazing power of a dog's nose, trained to detect bombs at airports, sent to search for survivors¹ after earthquakes. And now the fight against Coronavirus could get some four-legged help too. From dogs like storm and Asha. They're part of a British charity medical detection dogs. Now if they can do this reliably, a real game-changer. The hope is that covid-19 creates a certain smell that specially² trained dogs can detect on people. Like they already do with malaria³ and some cancers.

They have 350 sensory⁴ receptors in their nose, a full human's got 5 millions. They've been training dogs like storm here to detect disease for more than a decade. and if covid-19 has a signature scent⁵, there's a good chance she'll end up in an airport helping⁶ find those who are infected. And the key here is that we can screen a lot of people very quickly and it's non-invasive. They hope to know if the disease can be sniffed⁷ out by July, allowing these dogs to become the new furry⁸ detectives on the frontlines.

我们都知道狗狗的神奇嗅觉，它们被训练在机场探测炸弹，被派去寻找地震后的幸存者。现在，狗狗也可能帮助战胜新冠病毒。比如暴风和阿莎，他们是英国慈善机构的医疗探测犬。如果他们真的能做到的话，局势将会大变。希望在于，新冠病毒产生的特定的味道可以被经训练过的狗探测出来。就像它们能嗅出一些疟疾和一些癌症一样。他们鼻子上有350个感觉感受器，一个完整的人有500万个感受器。十多年来，他们一直在训练像暴风这样的狗来探测疾病。如果新冠病毒有一种特别的味道，那么她有很大的可能会出现在机场，帮助发现那些被感染的人。关键的地方是，我们可以快速筛查出很多人，而且它是非侵入性的手段。他们想要知道在七月之前这种疾病是否能被嗅出来，这些狗能否出现在前线，成为新的毛绒侦探。
