Dogs that can smell coronavirus in human saliva show data from a German study



A study in Germany found that dogs could smell new coronavirus in the saliva of patients with COVID-19.

Researchers at the University of Veterinary Medicine in Hanover, Germany, found that dogs trained in the study could detect a difference between saliva samples from COVID-19-infected patients and those that were negative for the disease.

“For the 1012 random samples, the overall detection rate for dogs was 94 percent,” the study’s authors said.

A randomized, controlled, double-blind study included eight detection dogs trained to detect salivary or respiratory secretions in SARS-CoV-2-infected patients within one week.

Sizzling dogs were able to distinguish fairly accurately between saliva samples from infected and uninfected individuals.

“One hundred and fifty-seven true positive statements, 792 true negative rejections, 33 false negative or false rejections for 30 positive samples,”

; the study’s authors are quoted as saying.

The researchers explained that respiratory infections, such as SARS-CoV-2, produce certain types of compounds that can be described as “specific odor prints” that can be recognized by dogs trained to detect that odor.

“Dogs use a lot of intelligence to interpret smells. According to VCA Animal Hospitals, there are more than 100 million sensory receptor sites in the nasal cavity, compared to 6 million people. The human brain. In fact, it is estimated that dogs can smell 1,000 to 10,000 times better than humans.

“Unlike humans, dogs have an extra sense of smell that increases their ability to smell,” say VCA Animal Hospitals. “The organ serves as a secondary olfactory system specifically designed to maintain chemical communication.”

The authors of the study argued that these are preliminary data and that additional studies should be performed to help develop more reliable methods for screening COVID-19-infected patients. The researchers said the method was not only an alternative to laboratory tests, but also in public places such as sports events, mass gatherings, airports to prevent the spread of coronavirus.
