“By presenting 1012 random samples, dogs achieved an overall average detection rate of the percentage,” the authors said in the study.
BLOOD TEST IDENTIFIES THAT CORONAVIRUS PATIENTS MAY BE HELPER OR HARMFUL WITH STEROID TREATMENT
The randomized, double-blind controlled trial with 8 stumbling onion dogs that were trained for a week to trip over the saliva or respiratory secretions of SARS-CoV-2 patients.
Sniffer dogs can differentiate saliva samples from inflamed and uni-inflamed Americans with a moderate degree of accuracy.
“One hundred and fifty-seven correct types of positive indications, 792 smart negative rejections, 33 negative indications or rejections of 30 positive pattern presentations,” the test authors quoted.
The researchers explained that in respiratory infections such as SARS-CoV-2, certain compounds are produced that can cause what they describe as “specific olfactory fingerprints”, which can be known through dogs trained to trip over this smell.

“Dogs devote a lot of intelligence to the interpretation of smells. They have more than one hundred million sensory receptor sites in the nasal cavity, up to 6 million in people, according to VCA Veterinary Hospitals. The mastery of the dog’s brain true to odor research is approximately 40 times larger than the comparable component of the human brain. In fact, it is estimated that dogs can smell between 1,000 and 10,000 times more than humans.
“Unlike humans, dogs have an additional olfactory tool that increases their ability to smell,” according to VCA veterinary hospitals. “The organ serves as a secondary olfactory formula specially designed for chemical communication.”
The study authors stated that these were the initial effects and that they deserve to conduct additional studies to help expand more reliable screening strategies for patients inflamed with COVID-19. In addition to this as an option for laboratory testing, scholars said this approach could potentially be used in public places, such as sporting events, mass gatherings, airports to help prevent the spread of coronavirus.
