Finland’s coronavirus-sniffing dogs find Covid-19 carriers at airport
Four dogs trained to sniff out coronavirus infections have been working at Helsinki Airport since September 23, 2020. Researchers say the animals can detect Covid-19 infections in seconds with nearly 100 percent accuracy, even among asymptomatic patients.
Scientists are not exactly sure how the dogs detect the virus, but it could be a sweat odour. Passengers singled out by dogs are told to get a standard test to confirm if they are infected. The state-funded pilot scheme has allowed Finland to become the world’s second country after the United Arab Emirates had deployed sniffer dogs to detect Covid-19.
