Dogs to sniff out COVID-19 in Aussie airports
The canines can detect the coronavirus presymptomatically from sweat samples: researchers
Sniffer-dogs being trained to operate in Australian airports may be capable of detecting COVID-19 before a positive reading shows up in tests.
The dogs have been taught to recognise a specific odour in sweat samples and the aim is to use them alongside required PCR testing for international passengers from early next year.
