Sniffer dogs are usually used to detect drugs or explosives. But at Helsinki airport in Finland, they”re being utilised to test for coronavirus.
A pilot project is providing instant and pain-free COVID-19 testing on the spot.
The canines have already sniffed more than 2,000 test samples since their booth was set up a month ago.
Passengers wipe themselves with a cloth and then drop the sample into a container, which the dogs then sniff.
Earlier this year, researchers found that dogs can detect the virus with close to perfect accuracy, up to five days earlier than a PCR test.
