The dogs needed to be trained not to identify “false positives” in a bid to hack their reward system and obtain treats even if there were no Covid-19 samples in a given test.
“This means that the dog fully understands and gets a reward for a correct negative as well as a correct positive,” said Claire Guest, from the school’s Faculty of Infectious and Tropical Diseases.
Overall, the dogs were successfully able to identify between 94 and 82 percent of SARS-CoV-2 samples.
Dogs are already good at detecting cancer and other disease.. and now Covid–apparently with better accuracy than even tests! Dogs have better luck ignoring the false positives!
Just watch out for the dog flu 😷 🙂
