Bio-detection dogs are now estimated to be able to detect cases of Covid-19 with 94% accuracy, outperforming the accuracy of Lateral Flow Tests.  The study, which is not yet peer-reviewed, is being led by Durham University, London School of Hygiene and Tropical Medicine (LSHTM), and the charity Medical Detection Dogs. It has found that Covid-19 has a distinct smell that dogs can identify.  “Our robust study shows the huge potential for dogs to help in the fight against COVID-19.” Dr clare guest The dogs can detect odours even from people who are asymptomatic, regardless of whether it is a high or low viral load. The canines, plus a confirmatory PCR test for those detected, is estimated to discover more than twice as many cases and prevent transmission.
