Passengers at Finland’s Helsinki-Vantaa airport have the option of a different COVID-19 test done by dogs.

A team of 15 dogs is being trained to sniff out the new coronavirus. Some of them have been used before to detect cancers.

The passenger swipes their neck with a gauze, which is placed in a can. Then the dog goes to work, delivering the result immediately.

And, according to researchers, they can detect the disease in the early stages.

But the canine’s efficiency has not been proven so whoever gets a positive also needs to take an old-school swab test to confirm the result.
