WHAT’S BEING CLAIMED:
- Researchers say that sweat from COVID-19-positive people gives off a different odor than those negative for the virus.
- The results of their study suggest that dogs could detect the scent of COVID-19 from ancillary sweat.
- This means that canines could provide a new way to rapidly test for the virus.
Humans have long taken advantage of the dog’s keen sense of smell. Canines have been used to sniff out all kinds of things from bombs, drugs, and even in the medical field to detect certain kinds of cancer in over 2,000 modern scientific studies. It looks like our furry friends may also be able to detect COVID-19.
According to researchers in Paris, and in other places, people infected with the virus have sweat that gives off a unique odor- one that canines can detect. Outside Paris, at the national veterinary school in Alfort, a new study was conducted where researchers trained 8 Belgian Malinois shepherds, from a group of 18 dogs (trained to detect explosives and colon cancer), to do so.
They could sniff out the scent of the virus in the sweat of infected individuals almost perfectly at an overall rate of 95%. Four of the dogs were able to identify a COVID-19 positive sweat sample 100% of the time.
Armpit perspiration was collected from 168 COVID-19-positive participants for the coronavirus study. Jars containing samples were placed in a line of 3, 4, 6, and 7, only one containing a positive sample.
Authors of the study say that the results of their study provide proof that people infected with COVID-19 produce ancillary sweat that has a different odor that dogs can differentiate from COVID-19 negative patients.
The possibility of COVID-sniffing dogs provides a potential “tool” for pre-testing or rapid testing people who may be COVID-19- positive. That’s absolutely great news with mass testing lacking in many parts of the world.
