According to the Washington Post, eight Labrador retrievers are being trained under a University of Pennsylva research project to determine whether cnes have the capability to detect an odour associated with the coronavirus."We don't know that this will be the odour of the virus, per se, or the response to the virus, or a combination," said Otto, who is leading the project.What they learn is that there's something different about this sample than there is about that sample." James Logan, head of London School of Hygiene & Tropical Medicine's disease control department, called cnes a "new diagnostic tool" that "could revolutionize our response to COVID-19." He said on Tuesday that his research team expects to begin collecting COVID-19 samples "within a matter of weeks" and working with the charity Medical Detection Dogs to train cnes soon after."We are simultaneously working on a model to scale it up so it can be deployed in other countries at ports of entry, including airports." Meanwhile, in Pennsylva, Miss M., Poncho, and six other chocolate, yellow and black Labs have begun their first stage of training, which is learning to identify an odour for a food reward.
