The smell of dogs Specializing in scents and smells could provide a cheaper, faster and more effective way to detect COVID-19, scientists say after reviewing 29 studies where dogs were used for detection. Corona virus disease.
These hunting breeds, known to have the most sensitive noses among dogs, have been found to detect Covid, including variants as well as long Covid, in symptomatic, pre-symptomatic and asymptomatic patients with sensitivity and specificity comparable to or better than the current gold standard RT tests. -PCR or antigen tests.
“Although many people have heard of the extraordinary abilities of dogs to help humans, their value in the medical field is remarkable, but they are not ready for medical use in the real world,” said Tommy Dickey, of the University of California, Santa Barbara, US. . , and the corresponding author of the study.
In one reviewed study, four dogs detected the same drop (0.05 mL) of odorant content dissolved in a volume of water filled over 10.5 Olympic-sized swimming pools, reports this study published in the Journal of Osteopathic Medicine. .
Olympic swimming pool It measures 50 meters in length, 25 meters in width, and between 2 and 3 meters in depth.
Scientists said one of the main benefits of using dogs to detect Covid was the speed with which they gave results, which can be obtained in seconds to minutes.
Moreover, it didn’t require expensive lab equipment or creating mountains plastic wasteAnd they said, unlike traditional diagnostic methods.
Include 19 different dog breedsTaken together, all 29 of these studies analyzed more than 31,000 samples by more than 400 scientists from more than 30 countries.
While in some studies, scent dogs sniffed people directly, sometimes in public as a health check, in others they sniffed samples of sweat, saliva, or urine.
Dogs are known to have as many as 300 million odor-related cells, compared to only 5 or 6 million in humans, and use a third of their brains to process odor information, compared to just 5 percent of human use.
The dogs have been trained and have been successful in recognizing specific patients crabsParkinson’s disease and diabetes, by inhaling certain compounds created in the affected body.
Dickey and his team believe their research shows the aptitude of scented dogs for mainstream medical applications.
“After conducting this review, we believe that scent dogs deserve their place as a serious diagnostic methodology that can be particularly useful during epidemics, and perhaps as part of rapid health checks in public settings.
“We are confident that scent dogs will be useful in detecting a variety of diseases in the future,” Dickey said.
