Dog Detectors. Now Dogs Can Nail You With Covid-19

The sense of smell in dogs is unparalleled, which is even more sensitive than the most advanced man-made instrument. They possess up to 300 million olfactory receptors in their noses, compared to about six million in humans.

Once trained, medical detection dogs are able to smell metabolic changes to people’s breath and sweat. Their sense of smell can even be more accurate than conventional COVID-19 tests.

The United Arab Emirates has 38 sniffer dogs working at its airports that can identify infected persons at a 98.2% success rate. Police trained the dogs to recognize the scent of COVID-19 using samples of sweat from people with confirmed infections, collected by holding a swab in an armpit for a few minutes.

Several other countries including Finland, the United States and France have also been running their own dog training and trials of canine detection of COVID-19.

Can Peanut Butter Save Us from Coronavirus?

Peanut Butter

“Identifying asymptomatic carriers is absolutely critical in stopping the progression of the pandemic, I believe,” Professor Small says. “So if there is odour loss with some — even if it’s only a small percentage of people — identifying them as carriers would be significant.”

Losing one’s sense of smell isn’t like losing one’s car keys. When the keys go missing, you recognize the loss in an instant. But a person’s sense of smell can slip away quietly, over a period of time, without the person noticing it is going, going, going, until it is effectively gone.

Small and her pals agreed that a simple do-it-at-home sniff test, using common household items, would allow participants — the great mass of us — to start tracking their sense of smell. In this way, an asymptomatic carrier who feels like a million bucks, but notes a diminishing sense of smell one day to the next, could consider quarantining, ASAP, instead of carrying on until their olfactory sense disappears altogether.

Hence, says Small, the birth of the peanut butter sniff test. Peanut butter, so good on toast, and always a friend to jam, is a North American staple that stimulates the olfactory sense exclusively, unlike, say, ground coffee — a treat to inhale, no doubt — but a fragrance that fires both our sense of smell and the trigeminal nerve governing sensations like “pain and tickle,” which influence how one registers an odour.

As a control on the peanut butter, sniff-test participants are asked to breathe in a snout full of vinegar, another household staple, like coffee, that fires the trigeminal nerve. The big idea? If a subject is registering the vinegar, but the scent of the peanut butter is fading away, they can be confident their sense of smell is decreasing.

“If we find there is a trajectory of diminishing smell over days, we would be able to identify asymptomatic carriers, even before they were conscious of losing their smell,” says Small. “And in those, let’s say, five days, there could otherwise be lots of transmissions.”

And what if you have a peanut butter allergy? Ouch!

Self-Monitoring Your Sense of Smell May Help Detect Coronavirus

A healthy (or unhealthy) sense of smell has always been likened to the ‘canary in the cole mine, alerting us to possibly underlying health conditions. It is no surprise that this human sensory tool is now being linked to the early identification of COVID-19

Along with fever, cough and shortness of breath – many coronavirus (COVID-19) patients report a temporary loss of their sense of smell. It appears that olfactory loss is significantly greater in COVID-19 patients compared to the loss that is often experienced during a cold, and less commonly, in non-COVID-19 influenza patients. In some countries, such as France, a patient who claims to have a sudden onset of olfactory loss will be diagnosed as a coronavirus patient – without even being tested. A similar approach is being considered in the UK. Based on this data, Weizmann Institute scientists, in collaboration with the Edith Wolfson Medical Center, developed SmellTracker – an online platform that enables self-monitoring of an individual’s sense of smell – for the purpose of detecting early signs of COVID-19 or in the absence of other symptoms.

This Woman Can’t Even Smell Burnt Toast?

Losing your sense of smell is called Anosmia. Our sense of smell has a significant impact on what we taste.

“It’s like eating a box of tissues,” Chloe Donovan explains. “You only get texture and temperature.”

Smell is a human early warning system, it prevents us from putting bad things in our mouths amongst another things.

Donovan says she once “nearly set my kitchen on fire” when she accidentally turned the toaster on while putting groceries down on the kitchen counter.

It was only after her son got home from school and smelt something burning that they discovered a blackened loaf of bread on top of the toaster.
