 Helsinki Airport has started making use of dogs to detect COVID-19.The airport in Finland is deploying trained sniffer dogs as part of a new trial after researchers said that in preliminary tests, dogs could "identify the virus with nearly 100 percent accuracy," including "days before before a patient developed symptoms," The Guardian reports. They can reportedly detect it in 10 seconds or less."It's very promising," University of Helsinki researcher Anna Hielm-Björkman, who is overseeing the trial, told The Guardian. "If it works, it could prove a good screening method in other places."The trial reportedly involves having passengers use a wipe to dab their necks, which one of the dogs then sniffs, and if it detects the coronavirus, the passenger can then take a polymerase chain reaction test. Participation in the trial is voluntary, The New York Times reports.Hielm-Bjorkman told the Times that it's not entirely clear what the dogs are actually detecting, explaining that "we know how dogs detect it — by smell — but we have no clue what they detect yet." But she added, "If we find this out, we can train thousands of dogs across the world." Airport Director Ulla Lettijeff in a statement said "we are pleased" with the start of the trial, adding, "This might be an additional step forward on the way to beating COVID-19."
