Researchers at the Veterinary University in Hannover, Germany, have found that dogs are able to surprise the coronavirus that causes COVID-19 with surprising accuracy.
In the study, they found that eight German military dogs were able to correctly detect the presence of coronavirus in 94 percent. Time after you have been training for only a week. Bloomberg reports.
“We think it works because the metabolic processes in a patient’s body change completely,” University professor Maren von Koeckritz-Blickwede said in a video the university posted on YouTube. “We believe that dogs are able to detect a specific odor caused by metabolism.
Despite the fact that dogs were used at airports and elsewhere to spy on various contraband materials and even explosives, “people didn̵7;t really realize what a dog could detect sick from non-sick patients,” says Holger Volk. Small Animal Clinic, Veterinary University, Hannover, in video.
The researchers suggested that the dog’s sniffing method could be used in “public places such as airports, sports events, walls, or other mass gatherings,” based on a video, but only in addition to existing laboratory tests.
COVID-19 samples were completely randomized, so neither dog handlers nor investigators knew which samples were positive and which were not. In other words, the researchers guarded against the “smart Hans” effect, in which animals seem to solve complex problems but actually take instructions from the people of their caretakers.
