Dogs bruh. Aren't they the frickin' best?!
Apparently, man's best friend may have a new side gig as COVID-detecting heroes! Researchers at the University of Veterinary Medicine in Hannover, Germany (in cooperation with the Bundeswehr, the Hannover Medical School and the University Medical-Centre Hamburg-Eppendorf)have found thatcanines can actually be trained to detect the presence of coronavirus using their super keen sense of smell.
After just a week of training, eight dogs from Germany's military were able to accurately identify the coronavirus with a 94% success rate, Bloomberg reports.
The samples were automatically distributed at random to ensure neither the dog handlers nor the on site researchers knew which samples contained the virus and which were used for control purposes. Surprisingly, the dogs were able to identify samples from those infected (virus positive) and those not infected (virus negative / control sample) with an average sensitivity of 83% and a specificity of 96%. "Sensitivity" refers to the detection of the actual virus whereas "specificity" looks at the dog's ability to identify the control samples (aka the virus negative samples).
“We think that this works because the metabolic processes in the body of a diseased patient are completely changed,” Maren von Koeckritz-Blickwede, a professor at the university, explains in this YouTube clipabout the initiative. “We think that the dogs are able to detect a specific smell.”
“People have not really realized the potential a dog could have to detect diseased from non-diseased patients,” says Holger Volk, head of the small animal clinic at the University of Veterinary Medicine Hannover. Here in the United States, dogs have found excellent job security at airports and other venues sniffing out explosives, narcotics, and all kinds of other contraband. Couple this with their potential newfound ability to detect the virus that's causing today's worldwide pandemic and services from our favorite furry friends may be in high demand very soon. Realistically, (in addition to lab testing) doggos could be employed in high traffic / public areas like places of travel, sporting events, borders, and other mass gatherings to sniff out anyone infected with COVID-19 and help prevent any further outbreaks or spread of the virus.
While these are just preliminary studies, things appear to be promising. According to Von Koeckritz-Blickwede, the next step will be to train dogs to differentiate COVID-19 samples from other diseases like influenza (aka the flu). Hopefully these good boys (and gals!) are up to the test and pass it with flying colors!
