A team of dogs was trained to detect coronavirus in hospitals. A study showed that 95% of the dogs could correctly identify patients with the virus in just 5 minutes. The dogs had a 100% success rate when correctly identifying patients with coronavirus. These dogs were trained to detect the virus by smelling a patient’s breath and sweat.
How Are Dogs Trained to Sniff Out Coronavirus?
To train these special dogs, handlers first show them samples of patients’ breath, sweat, and urine that contain the virus. Once they learn what smells like corona, they go into different rooms where they sit behind either someone who has the virus or someone who doesn’t (the control).
They sniff out which patient has coronavirus and which one doesn’t. The dogs are then tested on their ability to accurately identify specific coronavirus cases by providing samples from volunteers infected with coronavirus and those without it. If the dog correctly identifies all the infected samples, he will be considered “trained” and ready for duty in hospitals across Japan.
Why Do These Dogs Have a 100% Success Rate When it Comes to Detecting Coronavirus?
The dogs can correctly identify patients with coronavirus in just 5 minutes. This is much faster than the current diagnostic methods, which take hours or days to produce results.
The dog’s nose is much more sensitive than a human’s nose and can detect odors at concentrations 1 million times lower than humans can detect. Doctors have been using these dogs for over 2 years now, so they have had time to perfect their sniffing skills.
Doctors place a cotton swab in the patient’s mouth, close off both nostrils, and then watch the dog closely to see if they detect something unusual. If they do, the dog will sit down next to that person. These dogs are highly accurate in detecting coronavirus because they can smell tiny amounts of viral RNA on patients’ breath.
Unlike other diagnoses methods, this method doesn’t require expensive equipment and only takes 5 minutes per person. Dogs seem like an unlikely candidate for diagnosing coronavirus; however, they provide an effective detection method with minimal cost and minimal invasion of privacy (unlike other tests).
Conclusion
Dogs have a great sense of smell and have been trained to identify the coronavirus. With a 100% success rate, these dogs can be instrumental in preventing future virus outbreaks.
In the future, the hope is that the dogs can be used to help prevent outbreaks from happening and be able to identify those who have been infected with the virus.
