A German veterinary clinic has trained sniffer dogs to detect coronavirus
in human saliva samples – with 94% accuracy.
The dogs are conditioned to pick up the “corona odour” that comes from cells
in infected people, said Esther Schalke, a vet at Germany’s armed forces school for service dogs.
Filou, a three-year-old Belgian Shepherd, and Joe Cocker, a one-year-old
Cocker Spaniel, are two of the dogs being trained at Hanover’s University of Veterinary Medicine.
“We did a study where we had dogs sniffing samples
from COVID -positive patients and we can say that they have a 94% probability
in our study… that they can sniff them out,” said Holger Volk, head of the veterinary clinic.
“So dogs can really sniff out people with infections and without infections,
as well as asymptomatic and symptomatic COVID patients,” he added.
