Dogs For Coronavirus Screening Examined

By Zach Segal, Published Aug 06, 2020, 11:41am EDT (Info+)

While thermal temperature screening is the surveillance industry's most marketed response to coronavirus, thermal screening cannot detect asymptomatic carriers and has limitations in how it can be deployed.

Are dogs the answer to fast and accurate coronavirus screening? IPVM reviewed studies conducted in Chile, Finland, France, Germany, the United Arab Emirates, the United Kingdom, and the United States that are evaluating using dogs for coronavirus screening.

IPVM examines the tradeoffs in this approach to detecting coronavirus.

Update: This report has been updated as more countries trial using canines for screening.

I first thought it was a stretch for this industry to delve into temperature screening but this just might be it.

Will we be seeing IPVM's breakdown of temperature screening accuracy in Labradors versus German Sheperds?

Wouldn't you want to find out if Shar-Pei's and Lhasa-Apso's are actually highly vulnerable and possibly spying for the Chinese government?

Take pugs, for example. Most people don't even realize they come from China because they buy from OEMs.

Seriously, there's a lot to find out about this industry, and most of it is adorable and likes scratches.

In all seriousness, this is an alternative to those shady fever cameras.

Next time somebody wants to get a fever camera, we can say, "Just get a puppy, man. You'll be much happier."

(Okay, not entirely serious)

I love dogs, including highly trained dogs. As mentioned in the article, it'll take 6-8 months to train them so timing is a challenge. The other big problem is scalability. It's going to be pretty difficult to breed and train 10's of thousands of snouts.

Then we'll get a vaccine and the canine unemployment rate will skyrocket and the SPCA's will be overwhelmed in place of the hospitals! At least the canine CARES Act won't cost nearly as much! $100M (factoring in government waste) as opposed to $2T+

This made me laugh thanks John. I think it was more the picture but thank you

and I still think fever cameras are bs ;)

I could see using the dogs as a broad based screening tool,like in an airport,with a quick lab test to confirm. (No not another sniff by a labrador retriever )

Use dogs to identify people with the virus? Why not? It makes perfect sense when you realize that in the future we'll use dogs to identify Terminators.

For quite a while I was reading this article and waiting for a line saying this was a joke. Apparently, this isn't a joke, which is great! Dogs are amazing!

The mechanism of how they do it isn't fully explained, but perhaps I should read the original studies.

For example, would the dogs distinguish between COVID-19 and hundreds of other coronaviruses present in humans (AKA "common cold")?

Hi Boris, dogs aren't smelling diseases, they are smelling changes in a person caused by disease. So dogs aren't noticing you have a virus, they are picking up on a symptom of the virus. This article explains it further. Also, this is why it's hard to replicate with machines. We don't know what they are smelling necessarily, just that they are smelling something and it enables them to differentiate between healthy and sick people. It is really interesting and sounds crazy, but it works in a lab and might work outside of one.

I like my fellow canines, however the pseudoscience summary expectations may far outweigh the science method proposals where yet again media upside perpetuates its own invalid distinction into the minds of the unambiguous overlords of false interpretation. In other words, the hand that guides is not the same hand that leads.

End case, I would not base a human life expectancy on the science of naive, reactionary spectators tossing coins into the wishing well.

Intellectually we have the resources among ourselves to decipher and determine our best course of actions steeped in hundreds of weathered evaluations, testing and falsifying both certainty and uncertainties within the constraints of the data collected. Hence we are not blind....but if testing the sound waves of a duck's quack was warranted where is the proof? Science driven or internet derived sciences of the non-academic minds-cape?

Dogs are extremely accurate in labs. Previous work that I cited in the article says dogs will be worse in real life, but still a lot better than a coin. Our current tests for Coronavirus are not perfect, and there is a clear immediate need for new solutions to fill gaps. Dismissing science because it isn't finished is foolish right now.

A dog will probably not be as accurate as a PCR test in real life, but reaching the level of antigen tests is quite possible, and greatly surpassing fever detection for diagnosis is likely.

Can't wait for IPVM's article with a canine comparison & line up.

Which is the best fit for your application? I'm thinking a canine calculator for the specifying applications might need to be added in the IPVM toolbar.

Border Patrols Top pick, Pre-K - 6th graders Top Pick. The possibilities are endless on what you guys could evaluate.

What do you do with outdated equipment you've tested vs a test panel of dogs?

Boss just came in! Gotta get back to work. He wasn't buying that I was doing research on COVID applications.

Update: Helsinki-Vantaa Airport is testing out using dogs for coronavirus screening. We will continue to follow developments.

We have updated the report because several countries have joined the UAE in using dogs for coronavirus screening but there has not been widespread adoption and after 5 months of trialing canine screening in Helsinki airport, the Finnish government has declined to expand the program citing a lack of evidence of its efficacy.
