Trained on smelly socks, bio-detection dogs sniff out COVID-19

Sniffer dogs trained using smelly socks worn by people infected with the SARS-CoV-2 virus could soon be used at airports or mass gathering venues to pick up the “corona odour” of COVID-19-infected people, British scientists said on Monday. Working in teams of two, the COVID-trained dogs could screen a line of several hundred people coming off a plane within half an hour, for example, and detect with up to 94.3% sensitivity those infected, the scientists said.
