Dogs’ ability to sniff out whether people are infected with Covid-19 will be put to the test by British researchers, in a bid to develop a fast, non-invasive means of detecting the disease.
Britain’s government said on Saturday (16) it had given £500,000 towards the research, which will be conducted by the London School of Hygiene and Tropical Medicine, Durham University and a British charity, Medical Detection Dogs.
“Bio-detection dogs already detect specific cancers and we believe this innovation might provide speedy results as part of our wider testing strategy,” innovation minister James Bethell said.
Six dogs – labradors and cocker spaniels – will be given samples of the odour of Covid-19 patients from London hospitals, and taught to distinguish their smell from that of people who are not infected.
Medical Detection Dogs said it had previously trained dogs to detect certain cancers, Parkinson’s disease and malaria.
If successful, an individual dog could check up to 250 people an hour and be used in public spaces and at airports.
Researchers in the United States and France are attempting to train dogs to detect the disease too.
A small number of dogs are also known to have contracted Covid-19, most likely from their owners, according to vets in the US, the Netherlands and Hong Kong.
