Now, United Kingdom researchers are testing the idea that dogs can detect Covid-19. According to an article in Bloomberg's CITYLAB, the London School of Hygiene and Tropical Medicine (LSHTM) is forging ahead with the project with high hopes. Will it work? "There’s a good chance that it will," writes Feargus O'Sullivan. "Dogs are already widely used to detect the presence of cancers, bacterial superbugs and neurological diseases such as Parkinson’s. Working with the charity Medical Detection Dogs, the LSHTM has previously carried out a successful training program that demonstrated dogs could detect malaria, creating a test that exceeded required World Health Organization standards."
The head of LSHTM's Department of Disease Control, James Logan, says “We know diseases have odors — including respiratory diseases such as influenza — and that those odors are in fact quite distinct. There is a very, very good chance that Covid-19 has a specific odor, and if it does I am really confident that the dogs would be able to learn that smell and detect it.”
