Police in Chile are training dogs to detect those with the coronavirus.
A dog’s nose is about 50-times more sensitive than a human’s.
These dogs have already been working for years in detecting explosives. They only need to learn a new smell.
Germany, Finland, France, and England all have dogs that can detect people with COVID-19, even when asymptomatic.
The virus itself does not have a smell, but the infection generates a certain type of sweat the dogs can detect.
Chilean police hope to have these four dogs ready to start patrols in mid-September.
