While the world scrambles to get quick and easy Covid tests, it looks like dogs might be the answer.
There have been Covid tests with dogs before, but now Finland has got an almost 100% success rate in a new trial.
Even days before a patient develops symptoms.
Four dogs have already started Covid sniffing work at the country’s capital Helsinki airport.
Researchers at the University of Helsinki said the dogs can detect coronavirus in less than ten seconds – which proves this method money saving.
“It’s very promising. If it works, it could prove a good screening method in other places,” said Anna Hielm-Björkman of the University of Helsinki.
After collecting their luggage, arriving international passengers are asked to dab their necks with a wipe. In a separate booth, the jar containing the wipe is then placed next to others containing different scents. The dog then starts sniffing, reports the Guardian.
The dog shows it has detected the virus by yelping, pawing or lying down.
If positive, the passenger takes another test to verify the verdict.
