Tests? We Don't Need No Stinking Tests!

Dogs are being enlisted in the fight against the novel coronavirus. Researchers at the University of Pennsylvania are testing a pack of eight Labrador retrievers to find out if their sensitive snouts can detect the pandemic virus by scent, Karin Brulliard reports for the Washington Post.

Humans have trained our canine friends' finely tuned noses to sniff out other deadly diseases, including malaria, diabetes, some cancers and Parkinson’s disease, reported Ian Tucker for the Guardian in 2018. Other research has shown that viruses give off a particular smell, Cynthia Otto, director of the Working Dog Center at UPenn’s School of Veterinary Medicine, tells the Post.

If the dogs’ 300 million scent receptors can be trained to smell the novel coronavirus they could eventually be used in public places such as airports, businesses or hospitals to quickly and easily screen large numbers of people. Because this diagnosis by dog would depend on the smell given off by people infected with COVID-19 it should have no problem picking out asymptomatic carriers.
