After just a few days of training, dogs in Germany proved capable of identifying people infected with COVID-19, according to researchers. The dogs, part of a study by a veterinary university in Germany, were able to sniff out the coronavirus with stunning accuracy. According to the pilot study published Thursday in BMC Infectious Diseases by the University Veterinary Medicine Hannover, eight dogs from Germany's armed forces trained for just five days before they could identify the virus in humans. For the study, dogs were trained using the saliva of people who tested positive for COVID-19 and the saliva or people who tested negative and have no history of respiratory disease. Von Köckritz-Blickwede said the next steps will be to train the dogs to differentiate between coronavirus and other diseases, such as influenza.
