Bio-Detection Dogs Could Sniff Out COVID-19 Among Air Travelers

No one knows for sure what air travel will look like when the world emerges on the other side of this pandemic. Airports and airlines are already taking extreme precautions to protect the health and safety of travelers worldwide. Some are being forced to wear face masks, undergo full-body disinfection at the airport, and even submit to pre-flight blood testing. Now, it seems the next weapon in the fight against COVID-19 could involve highly trained dogs.

A team of London researchers is working to determine whether bio-detection dogs can sniff out the COVID-19 virus in humans. The group previously collaborated on a successful project to train canines to detect malaria in humans. With a high degree of accuracy, the dogs can hone in on specific odors given off by the virus, even in infected people showing no symptoms. They can also detect changes in body temperature that might indicate a fever. The team used similar methods to train other dogs to diagnose Parkinson’s disease, cancer, infections, and other medical conditions.

It sounds implausible, but consider that we already rely on dogs to detect things like drugs and explosives. At the heart of the team’s research is whether COVID-19 has a distinct smell or, more specifically, changes the way our bodies smell. According to the project’s Indiegogo page:

“Many diseases change our body odor. This has been shown many times in scientifically robust experiments. Recent research on flu viruses, and other respiratory diseases, has shown that these diseases also interact with the human immune system and change human body odor. There is a very good chance that COVID-19 has a distinctive body odor.”

According to Medical Detection Dogs co-founder, Dr. Claire Guest, the screening is non-invasive. “When sniffing people, the dogs will not need to make contact but will sniff the air around a person. The dogs will therefore not be in direct contact with the people screened to prevent the risk of spreading the virus.” If the long-term project is successful, the team is hopeful the dogs could rapidly screen up to 250 people per hour. 

“The dogs will not be in direct contact with the people screened to prevent the risk of spreading the virus.”

Dr. Guest is also quick to point out that the training process will not endanger the dogs. “The samples that the dogs will be trained on at the center will be deactivated (dead) virus and therefore of no risk to the dogs or handlers.”

The group launched an ambitious Indiegogo campaign to solicit donations for the research project. If the campaign is fully funded and the training is successful, the dog teams could be deployed on a global scale. This could be especially useful toward the end of the epidemic to help stop a re-emergence of the virus after it’s under control.

Should You Travel After Getting a COVID-19 Vaccine?
what the covid vaccine means for travel businessman using mobile phone at airport protective mask

With the Pfizer, Moderna, and Johnson & Johnson vaccines now being administered around the U.S. and pictures of vaccine jabs and posing with vaccination cards spreading across social media, naturally, everyone’s thoughts are turning to when they can finally hop on a plane and take that much-needed vacation. But just because the vaccine rollout is underway doesn’t mean we can throw caution to the winds, as Dr. Fauci, the Centers for Disease Control and Prevent (CDC), and numerous health and public safety officials have said. There are the new COVID variants to consider, not enough people may take the vaccine to start ensuring herd immunity (which could require anywhere from 70-90% of the population being vaccinated to be fully effective), and states may reopen too quickly, sparking outbreaks. Plus, with international travel, you might be heading to a country that may not have as many citizens vaccinated or even have vaccines yet, leaving the potential for COVID to be brought in or out. 

So what does that mean for your travel plans? There are still a lot of unknowns, but we’ve distilled all the information floating around out there down to some essential must-knows.

After COVID-19, Travel Bubbles Could Be the First Step for Travelers

It’s clear that merely waiting out the COVID-19 pandemic isn’t a viable option. It’s likely to be an issue for the foreseeable future, at least until we can develop a vaccine. In light of that realization, the world has slowly begun to reopen. Some countries are tentatively reopening to foreign visitors, while others are reopening only to visitors from neighboring countries in what are being called the world’s first “travel bubbles.”

This month, Estonia, Lithuania, and Latvia agreed to reopen their borders, but only to one another. It’s Europe’s first official travel bubble. The concept is simple: The three countries will freely allow visitors from either of the two neighboring countries while limiting access to anyone else. Other travelers to these Baltic corridor countries would need to isolate for at least 14 days after they arrive.

Some Countries Consider Health Passports for Travelers, But There’s a Catch

The global pandemic has upended every aspect of our lives. Almost no facet of the world has changed and will continue to change more than travel. For domestic and international travelers, moving about the world will look very different for the foreseeable future. Travelers can expect increased scrutiny at airports, security checkpoints, and border crossings. Some destinations have already suggested instituting so-called “health passports” to screen potentially infected visitors. While it’s a great idea, in theory, there is a big catch.

The idea of health passports (also called “immunity passports”) is to provide foreign visitors with an official certificate confirming their immunity status. The process is simple. Upon entering a new destination, travelers would have their temperature taken and produce the virtual certificate on a smartphone to confirm their negative status. While the immediate need is to screen travelers for COVID-19, the concept could work just as well for other infectious diseases.
