London —
dogs have a strong sense of smell and can be used to identify people infected with the new coronavirus. Early tests have shown that sniffer dogs can detect this disease very accurately. This makes people hope that dogs can quickly play a role to help fight this epidemic.
E.T. Kosi and Mina are Finland’s latest weapons against the new crown virus. The
sniffer dog is using its unparalleled sense of smell to help with inspections at Helsinki’s Vantaa Airport to detect any passengers with this disease. The early results of
are encouraging. The accuracy of dog detection is very close to the results of cotton swab or PCR detection.
Vantaa City Deputy Mayor Timo Alonquito said: “We have conducted 16,000 to 17,000 PCR tests at the airport, and less than 1% are positive. If you compare the test results of these dogs, it is not 1%, the result is roughly the same. I don’t think there is a statistical difference.” In fact, the researchers said that these dogs have surpassed the role of cotton swab testing and can detect positive cases of new crown infection that are missed by the test.
dogs have been used to detect other diseases. Professor James Logan had been working on an experimental project using dogs to detect malaria before the outbreak of the new crown.
Professor James Logan of the University of London School of Hygiene and Tropical Medicine said: “From what it can detect, the dog’s sense of smell is absolutely amazing. What we are talking about is one part in a trillion, just like in two Olympics. Put a teaspoon of sugar in the water in a standard swimming pool. That's the ratio." Logan began to study whether dogs can detect the new coronavirus. Logan said: It's not the virus itself, but the changes in our body that cause changes in body odor so that dogs can detect it. "Z1z
is experimenting with dogs to detect the new coronavirus in the United States, Finland, the United Kingdom, Lebanon and other countries. The final results of many trials are expected to be published soon. If successful, more dogs can be deployed as detectors worldwide. Z1z
Logan said: “In environments with a large number of people and heavy traffic, these dogs are also capable of detecting. Therefore, the places we are studying include airports and other ports of entry, perhaps commuter train stations, or even work places, hospitals or schools. "Z1z
Therefore, man’s best friend may soon help with one of man’s biggest health challenges.
How sensitive is a dog's sense of smell
The overall sensitivity of a dog’s sense of smell is 1 to 1 million times that of a human, and it can use the sense of smell. To identify the identity of the owner and the like, such as by smelling the other party’s ass, we can know the other party’s gender, age, physical condition and mood at the time. This special smell ability allows the dog to be trained as a professional working dog. Then the dog How powerful is the sensitive sense of smell?

Among them, it is very sensitive to the smell of its owner and familiar people, so even if its owner is mixed with a strong smell of perfume or alcohol, dogs can distinguish and find the owner based on the light smell. Therefore, there are specially trained military dogs in the army, so if there is a missing person, this ability of dogs can play a big role. In addition, dogs seem to be able to distinguish twins by smell. Come.

In the future, dogs may become an important helper for humans to screen for cancer. And dogs can also smell epilepsy The patient’s sweat is warned. French scientists have found through experiments that trained dogs can smell the sweat of the epileptic author and give warnings in time.A lot of medical skills have been discovered, such as cancer, Parkinson, malaria and diabetes.
