Results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner – so no need to swab your throat or nose
Dogs can detect Covid-19 faster and more accurately than a PCR test, a new study shows.
Researchers looked at the ability of canines to recognise the virus and its variants, even when they are obscured by other viruses, like those from common colds and flu.
More than 400 scientists from over 30 countries contributed to the study as well as 147 scent dogs, according to the findings published in the Journal of Osteopathic Medicine.
After analysing many studies covering both field and clinical experiments, Professor Dickey and Junqueira found that dogs who are trained to sniff out scents are “as effective and often more effective” than antigen tests.
A total of 53 dogs were trained to sniff out Covid scents, while 37 were not and scientists found that the dogs that were not trained were in some cases “slightly superior” to those that were pre-trained.
“The previously untrained dogs have the advantage that they are not as prone to indicating on scents other than the Covid–19 associated scent,” the paper said.
The results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner. This means you won’t need to put a swab in your throat or nose.
How can dogs detect the virus?
This essentially comes down to the dog’s highly evolved nose with its ability to sense out smells quicker.
Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. And the part of a dog’s brain that is devoted to analysing smells is about “40 times greater” than humans. Canines also have ‘neophilia’, which means they are attracted to new and interesting odours
And so, with all these enhancements, dogs can detect very low concentrations of odours associated with Covid infections.
“They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools,” Professor Dickey said. “For perspective, this is about three orders of magnitude better than with scientific instrumentation.”
Scientists also found that in some cases, the animals were also able to detect the virus in pre-symptomatic and asymptomatic patients, “whose viral load was too low for conventional tests to work.”
Professor Dickey has said that dogs can also differentiate Covid and its different variants in the presence of other respiratory viruses. This included the common cold or flu.
“They’re much more effective. In fact, one of the authors that we quote in the paper commented that the RT-PCR test is not the gold standard anymore. It’s the dog. And they’re so quick,” he added. “They can give you the yes or no within seconds if they’re directly smelling you.”
How was the study conducted to see if dogs can really detect Covid-19?
In some studies, the dogs gave a person a quick sniff, sitting down to see if the person has Covid. In another study, the dog was given a sweat sample to smell for a few minutes.
The press release has said that scent dogs, such as beagles, basset hounds and coonhounds are the ideal candidates for sniffing out the virus, given their “natural tendencies to rely on odours to relate to the world.”
But the studies which the researchers analysed showed a variety of dogs were up for the challenge and were able to sniff out the Covid odour. With a few weeks of training, puppies, older dogs, purebred and mixed breeds, both male and female were able to sniff such odours out and “all performed admirably,” the Eureka Alert press release said.
Although there has been success with dogs detecting such viruses, researchers believe there are still many challenges with using dogs for medical diagnoses.
“There’s quite a bit of research, but it’s still considered by many as a kind of a curiosity,” said Professor Dickey.
In conclusion, Professor Dickey and Junqueira said after reviewing the studies, believe that scent dogs deserve “their place as a serious diagnostic methodology that could be particularly useful during future pandemics, potentially as part of rapid routine health screenings in public spaces.”
“Perhaps, most importantly, we argue that the impressive international quality and quantity of COVID scent dog research described in our paper for the first time, demonstrates that medical scent dogs are finally ready for a host of mainstream medical applications,” they added.
The Journey of Nancy Sinatra: Resilience, Transformation, and Success
The well-known Frank Sinatra’s daughter, Nancy Sinatra, has never been out of the spotlight. She was exposed to the opulent lifestyle that came along with her father’s fame while growing up in a magnificent New Jersey home. Despite this, the family was concerned about the attention and throngs that collected around their home.
Nancy had to face challenges even though she came from a wealthy background to become a great singer. Due to the poor reception of her early releases, there were even reports that her father’s record label was thinking of removing her. Nancy, though, was unmoved. She embarked on a mission to alter her situation.
Nancy made a triumphant return to the music business by altering her image and undergoing voice training. Her transformation from an unfulfilled artist to a hitmaker is proof of her ability, perseverance, and determination. She is an inspiration to budding artists who are overcoming obstacles in their own lives.
Nancy faced difficulties even though she achieved incredible success in the music industry. After she left college early and discovered that her father’s record business would terminate her, her career seemed uncertain. But everything changed when lyricist Lee Hazlewood offered advice on how to pursue her career.
Singing down an octave, Nancy, with Hazlewood’s assistance, discovered her own voice. Additionally, he helped her update her appearance so that it more closely resembled the trendy “Carnaby Street” image. Nancy’s greatest degree of success was attained with her number-one hits, “Sugar Town,” “How Does That Grab You, Darlin’?” and “These Boots Are Made for Walkin’,” thanks to her renewed concentration. She even made her mark on the big screen, costarring on screen with icons of the motion picture industry like Elvis Presley and Peter Fonda.
Nancy made the decision to step back from the spotlight in the 1970s, even with her many accomplishments, so that she could spend more time with her family. But when she released her third album and posed for Playboy at the age of 54, she stunned everyone. Her work with well-known musicians such as Bono and Morrissey showed that her passion and musical ability were unwavering.
Nancy loved her father so much that she authored two books on his life. In recognition of her commitment to preserving his memory, she was awarded a star on the Hollywood Walk of Fame. Her distinct fashion sense—particularly her go-go boots—became strongly linked to her character. Those iconic boots, albeit she no longer owns them, left a lasting impression on her career and image.
Nancy has struggled in her personal life in addition to her musical career. She divorced young singing idol Tommy Sands after a few years of marriage. Nancy made the decision to prioritize her daughters’ schooling over her singing career. During this time, she met Hugh Lambert, who would become her second husband. Their marriage was sadly ended in 1985 when Hugh succumbed to illness.
Nancy Sinatra persevered through personal hardships to pursue a demanding career. Nancy’s Boutique was founded in 2020 as an internet-based shop where fans could purchase CDs, exclusive products, and autographed items. She also hosted the weekly radio show “Nancy for Frank” until 2021, during which she shared personal information about her life and her relationship with her late father.
Nancy has a vivid and strong personality that has inspired many, and her contributions to the music industry are absolutely remarkable. As long as she continues to pursue a wide range of activities, she will undoubtedly be recognized as a representative of her generation. Nancy Sinatra led a life marked by unwavering determination, transformation, and unmatched success.
