After just a few days of training, detection dogs can sniff out coronavirus infections. This is according to a new study, published on July 23 and which was piloted by the University of Veterinary Medicine Hannover, the Hannover Medical School and the German Armed Forces. The study established that if well-trained, dogs were able to discriminate between human saliva samples infected with SARS-Cov-2 and non-infected samples with a 94 per cent overall success rate.
