coronavirus. Finnish researchers are hopeful the dogs will prove to be faster and more accurate then conventional tests. It’s been established that people without any Covid-19 symptoms are capable of spreading the virus, and nasal swabs and temperature tests can be inaccurate and time-consuming.
But in preliminary tests, the dogs were able to identify the virus with almost 100% accuracy, even before a patient developed symptoms.It isn’t entirely clear how the dogs are detecting the virus although a study from the Alfort school of veterinary medicine in France suggests they can detect changes in the smell of infected people’s sweat.The Finnish dogs can detect the scent of coronavirus on a person within 10 seconds and traveller can be checked.
