It is good to see from an article by Fergus O’Sullivan April 6th 2020, that Scientists at the London School of Hygiene and Tropical Medicine (LHTSM) are hoping to train dogs with a particularly keen sense of smell to diagnose people with the COVID 19, even if they are displaying no symptoms. They are hoping that it works and that dogs can be trained to detect the disease, as dogs are already widely used to detect the presence of cancers, bacterial superbugs and neurological diseases such as Parkinson’s. Not all dogs are suitable for this training, but among the dogs they are using is a cocker spaniel and a Labrador retriever — who possess both an unusually acute sense of smell and the ability to be trained. Some already have experience with malaria screening.
