Trained dogs are able to detect the coronavirus infection via sniffing samples with more than 90 percent precision, dog handler Gustav Hotový told ČTK during a simulation of dog testing in a Prague elementary school with tens of pupils taking part in the simulation. Within the Search and Rescue Czech Republic team, Hotový trained dogs to recognize the infected samples and believes the method could be used for instance in schools, retirement homes, and companies, he said. The team has been training with samples from Prague's Thomayer Hospital, the Olomouc Teaching Hospital, and GPs. The project, financed by the private sector, started last April. The most valuable are symptomless patients as the dogs are not misled by other symptoms, such as fever. When put into practice, a positive "dog test" would be confirmed by an ensuing PCR test. Similar projects started last year abroad, too, for instance in Finland, France, and Germany.
