Corona virus-catching dogs have now been deployed at London's Heathrow Airport. According to Mail Online, these dogs have been specially trained to diagnose the virus by sniffing corona virus patients. A person infected with the corona virus has a specific odor on their body that these dogs can recognize.
When dogs confirm the corona virus in a passenger, they will be immediately sent to a quarantine and tested for corona to see if the dog has confirmed it correctly. These dogs are not sent to the passengers for sniffing, but the wipes are spread on the bodies of the passengers and the wipes are thrown into a cup lying in front of the dogs in a separate room, which these dogs sniff. The initiative also aims to protect dog owners from the disease.
