Trained dogs can recognize Corona infected people by their smell, according to a British study. Six dogs sniffed out samples from infected people with an accuracy of 82 to 94 percent, the London School of Hygiene and Tropical Medicine announced Monday. The result confirms earlier studies from Germany, among others. The British researchers used socks from 400 test subjects. 200 of the people were infected but had no symptoms or at most mild symptoms, 200 were in the control group. The dogs, which belong to the charity Medical Detection Dogs, were trained to the original coronavirus. However, even without additional training, they would have sniffed out the Corona variant relatively well, which was only discovered in southeast England, said study leader James Logan.

According to the British news agency PA, this is the result of a study by the government agency Public Health England (PHE).
