Claim: dogs can smell covid infections

Question

A CNN article came out and claimed that dogs may be able to smell infectious diseases, and can help detect covid in K-12 school. Is this true?

Comments

According to UC Santa Barbara Science and Technology, Dogs can technically smell "symptoms" of COVID-19 illnesses. Professor at UCSB Tommy Dickey did some research, after working with therapy dogs he decided to look into the science part of things and began to conduct a study. He claims dogs can do the same work that an at-home covid test does, which consists of 95% accuracy.  Which overall means dogs can sniff out Presymtimcatic, asymptomatic and symptomatic forms of covid-19.

Answer 1

According to the Hospital of Central Connecticut, technically dogs can smell the basic immune responses that the human body have to COVID-19 and other immune changes because a dogs sense of smell is incredibly strong. 

Your immune system has a signature smell that is unique to you and when you have an immune response to COVID-19 that smell changes to the point where dogs can recognize that something is off. 

According to the article linked below, a dog can identify if an individual has COVID-19 about as well as test and can identify individuals that have had COVID even after symptoms fade because the faint smell might still be different.

Great job. Thank you for explaining how dogs can detect the difference in a person's immune response. It is a widely known fact that dogs have a really good sense of smell and going further into explanation helped your credibility. I think another source would be helpful, but the source you did site is credible. It was also very helpful the way you summarized the information to give the reader of the fact check the information quickly with enough detail for understanding.

---

I think you did a very good job in proving whether this claim is true or false.  Providing the secondary article gave more insight on how dogs can smell an individual for COVID-19.

---

This is super interesting to me! I loved reading your breakdown of evidence and providing a strong article to prove that dogs can smell the difference in your immune system. Dogs are so smart and how could we not love them? I think you did a great job in proving your point, the only thing I wish was added was a quote with statistics from the article.

---

This is super interesting and you did a great job further explaining the issue and using a reliable source to back up your information. Separately, I think it's super interesting that something like this is being fact-checked, to me it feels like it would almost be common sense due to the fact that dogs have been used to sniff out tons of different physical objects and different illness' or bodily reactions.

---

I liked how you used a hospital as a source like the Hospital of Central Connecticut. This ensured that you would be getting data from health care professionals. You summarized the article well, and it is interesting that you noted that dogs can smell covid after the symptoms have faded. I would have liked to see some sort of statistic or quote from the article.

---

I really liked how you used a strong source to fact check your work. I also thought the information that you provided was very accurate. Fact checking through health care proffesionals and using data was a very smart idea as well. Something I wish I would have seen was some of the information from the article quoted.

---

This is an outstanding fact check with great sources. I love dogs and know they are amazing animals. The fact checker used great medical sources to support their check and ensure the author was correct.

---

Your answer was very strong due to you citing the Hospital of Central Connecticut since the source is actually from a hospital's website. Since it is very well knowing that dogs have a great sense of smell and looking at the reliable source made your answer very credible.

---

I think this is a really solid fact check, and I appreciate the source that was provided as it adds more legitimacy to the claim.

---

I thought this fact-check was very well thought out. I liked how you broke down the claim and found evidence that supported the claim well. I also liked how you picked a reputable source with a .org.

---

Your fact check did a great job determining whether the question was true or false. You used a reliable source from the Hospital of Central Connecticut, making your information trustworthy. The point about dogs being as good as tests and identifying COVID even after symptoms is a strong additional point. I would say a direct quote from the article could make your fact-check more transparent, but your healthcare source makes your answer credible!

---

This is an incredible fact-check! It's very thorough, yet concise and gets the point across, and includes the source from which the information was found. This is so fascinating to learn that dogs are capable of even more amazing skills!

---

I appreciated your detailed fact-check. It's a strong argument because your source is accredited. I would have liked to have at least one more source to back the other source as well. It's always better to show that there's been an equitable portion of research done on the topic. Overall, good work!

Answer 2

I also found a source confirming this. ABS News states, "Dogs can detect Covid with high accuracy, even asymptomatic cases". I would say that these two sources have strong enough evidence to deem this true.

Comments

Do you have a source link to ABS News? Is it a legitimate website?

---

I'd like to see a little more on the asymptomatic case, only because I thought the way the dogs can smell it was through the response of human immune system response. Should they be asymptomatic I'd love to know how it works!

---

This fact check could benefit from linked sources and further context about your quotes. I think that citing a direct source itself was a great way to support your fact check, so it would be even stronger with linked sources and more context.

Answer 3

According to a study done by The California Department of Public Health, "After 2 months of training on COVID-19 scent samples in the laboratory, the dogs achieved greater than 95% sensitivity and specificity for detection of the virus. " So I would say this is true. https://jamanetwork.com/journals/jamapediatrics/fullarticle/2804205#:~:text=After%202%20months%20of%20training,1%20to%20May%2025%2C%202022.

Comments

I believe the same thing! This is a great article to read on the scenario!

---

I like that you used a healthcare article from the California department of Public Health. This was a great source to fact check from! I like the fact that they have evidence of using labratory samples with dogs and showed actual stats to prove it. Something that would be nice to see is other article evidence to help back up and support this as well.

Answer 4

This is true, according to an articel from understanding animal research dogs are able to smell human sickness as changes in human hormones and compounds relased by sick cells are easy for them to pickup on.

Comments

This is a great answer! It would make sense that they can since there are a lot of dogs used for different types of diseases such as diabetes.

---

I believe the same thing! How did you verify if the website "Understanding Animal Research" is a reliable source? Also you forgot to select a ranking for your fact-check.

Answer 5

From personal experience, when I had covid my dog wanted to be no where near me. So personally I think yes this could be true.

Comments

Personal experience is a great addition to any fact-check. It's also a good idea to dig deeper and see what literature, research, or news sources have found on the topic as well to have a more complete fact-check.

According to this article, "two studies published in 2022 - one from France, one from Germany - show that dogs may be able to sniff out long COVID." This article states that dogs can be trained to detect human diseases such as cancer and that can include COVID

Answer 7

According to UCLA Health, it seems that specifically trained dogs are good at detecting COVID-19. Dogs have a history of assisting human with detecting disabilities and illnesses. For example, the article states that, "dogs can detect the presence of some chemicals in parts per trillion. This includes the volatile organic compounds produced by our bodies when we are ill, and which are released via sweat, urine, breath and the skin."

It was said that a few small studies were able to show that dogs could sniff out the Covid-19 infection. The article claims that more studies are needed to be absolutely certain, but the method is promising.

Answer 8

 

 

According to Medpage today, it is true that trained dogs have been shown to be capable of detecting COVID-19 in airline passengers with similar accuracy to PCR tests. In a randomized trial at a busy international airport, the dogs demonstrated 92% accuracy, with 92% sensitivity and 91% specificity compared to the RT-PCR test. They correctly identified 98.7% of skin swabs negative on PCR in a real-life setting at the airport. The dogs were trained to detect SARS-CoV-2 positive samples from negative samples and were successful in identifying positive cases even when exposed to the Alpha variant. This method shows promise for screening COVID-infected individuals in mass transit settings.

Answer 9

According to Understanding Animal Research.org dog's sense of smell can help detect diseases in humans. The article states, "Dogs' sense of smell is so subtle that they can notice the slightest change in human scent cause by disease. The tiniest shifts in hormones or volatile organic compounds released by diseased cells can be picked out by dogs." Although this article does not speak about COVID specifically you can infer that since covid is a type of disease it would be caught by a dog. They are able to detect many different disease and variations of diseases such as cancer. The article also states, "Canines proved to be able to correctly pick out the scent of children infection with malaria parasites 70% of the time from socks they had worn all night."

How would you rate the claim? Don't forget to select a rating for each fact-check. Thanks!

Answer 10

This is true

According to UCLA health, dogs can sniff out COVID-19 infections. In one study, 97% of trained dogs could sniff out COVID-19 from sweat samples. This makes them more sensitive than rapid antigen tests. According to NBC news, dogs only need "a few molecules" to identify a positive case.

The sources you used to fact-check this claim are credible and well-known. In terms of the content itself, the information seems to be accurate across both articles. I found an article from the National Institutes of Health that also confirms this claim to be true. The article also provides their testing methods, key findings, and statistics.
