Does sweat from someone infected with COVID-19 have a unique scent that dogs can detect? A new study from researchers at a veterinary school outside Paris trained 8 Belgian Malinois shepherds to identify the smell of COVID-19 in the sweat of infected persons. They later presented those same dogs with a number of samples. The dogs correctly identified an average of 95% of samples.
OUR TAKE: With a vaccine likely months away and with rapid testing still difficult to come by, training dogs to sniff out infected individuals could be one tool used by airlines or destinations to create an extra layer of security at low cost.
