Tests conducted with trained German Shepherds at a veterinary school in Maisons-Alfort (Val-de-Marne) show a 95% success rate in sniffing out the coronavirus that causes Covid-19.
Weeks of trails have produced positive results at veterinary school and research centre l’École Nationale Vétérinaire in Maisons-Alfort, where researchers say their German Shepherds have been trained to detect coronavirus.
During the trial, the dogs had to identify the presence of the virus by smelling sweat samples taken from subjects who were infected with Covid-19.
The school partnered with hospital Beaujon de Clichy to collect sweat samples from both infected and non-infected subjects. The sweat samples were then used to soak pieces of cotton wool which were placed inside metal cones.
The dogs then used their sense of smell to identify whether the sweat sample inside the cone was infected or not.
In 95% of cases, the dogs were correct.
