Can dogs detect Covid-19? A British charity believes so, and has begun training canines to sniff out the coronavirus following previous screening success with various illnesses.
Medical Detection Dogs, set up in 2008 to harness dogs' sharp sense of smell to detect human diseases, started working on the project late last month.
In its training room in Milton Keynes, in central England, the dogs are being intensively trained to sniff out samples of the virus, and indicate when they have found it to receive a treat.
The approach is based on a belief that each disease triggers a distinct odour, which canines are uniquely well-placed to smell.
