Can dogs detect people with coronavirus?

Can dogs detect people with coronavirus?

On the 23rd of last April, French media revealed that the Veterinary Science Department at the Maison Alvor College was conducting a pilot study to verify whether dogs trained in the search for drugs and explosives were able to identify the smell of Covid-19 in infected patients. In light of the first results, the study said, "The initial experiments showed very amazing results."

It seems that the bet has started to be fulfilled with satisfactory results, the features of which seemed to be well and encouraging, according to the study team. The second phase of the study begins this week to verify the authenticity of the first results that were reached during the past three weeks, where about twenty trained dogs accompanying firefighters and gendarmes participated in the tests of the first stage.

Sweat samples were taken from patients with confirmed Covid-19

Sweat samples were taken from patients confirmed to have Covid-19 and dogs were trained to recognize the smell of the virus. Then a sample was found that the diagnoses were positive in a room along with several other negative samples. The challenge was to find out if the dogs would recognize and stop in front of the positive sample, that is, the confirmed case of coronavirus infection.

The answer is yes, according to Dominic Grangan, professor at the National Veterinary School of Maison Alvor:

"Our big question was: Are we going to get the smell of a specific race ... After conducting multiple experiments, we concluded that dogs were able to distinguish between confirmed cases and those who have no infection." "The second step in the study, which will start this week, is to give the dog a sample of confirmed cases of positive or negative injury and to know whether he is pointing, barking or sitting when he smells Covid-19," Dominic Granjan added. Bark in a specific way and does not confuse positive or negative samples.

Experience has not said its last word yet

Dominic Granger, who has a strong hope for his research, demonstrates that dogs can turn into a very effective screening tool under the pandemic.

"The procedure will take another ten days. We cannot prove that the experiment under the current stage has said its separating word necessarily," he said. "It is dogs and it is not about machines anyway."

British study: trained dogs can quickly diagnose coronavirus

Last April, a team of researchers from the London School of Hygiene and Tropical Medicine in cooperation with the University of Durham and the charity Medical Examination Dogs in Britain said that specially trained dogs could be able to quickly diagnose the Coronavirus. The research team added, on the other hand, that "dogs can discover many diseases, including cancer, Parkinson's and bacterial infections thanks to their very strong sense of smell."

According to the study, a group of scientists taught three dogs from the Beagle family smelling lung cancer in blood samples from human patients. Dogs correctly identified lung cancer from a sample taken from a cancer patient at 96.7%, according to the test results. Further studies have been directed to verify the ability of trained dogs to detect other types of cancer, including breast and colon cancer.

Trained animals can test up to 250 people per hour

Scientists believe that highly trained animals can test up to 250 people an hour by smelling their scents. According to the British study areas, the use of trained dogs has proven that they can perform a large number of tests in a short time, which allows quick identification of infected people and isolation of those who have been infected with the virus.

Prospects and application of the experiment

If the experiment is successful, dogs can be deployed to airports when the outbreak of the Coruna epidemic ends, to quickly reveal the identity of the virus carriers, which "helps prevent the outbreak of the disease again." Dogs are well known to be used by security forces to detect drugs or weapons, but their superior sense of smell can also detect disease.
