Dogs trained to detect COVID-19

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". They sniffed the saliva of more than 1,000 people, both healthy and infected, identifying the coronavirus with a 94% success rate
 
University Professor Dr. Holger Volk 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."
 
It's another example of the relationship and interdependence between people and animals. And it makes you wonder, doesn't it? How much money and heartache could those dogs save people from, if they were stationed at a country's borders?
