Covid-19 has a specific scent and dogs can smell it!

Dogs can be trained to detect Covid-19 by sniffing human sweat.

Now, many countries around the world are considering using dogs as a quick, reliable, and relatively inexpensive way to identify people infected with Covid, or to do a quick check-up in certain circumstances, for example at airports.

Currently, dog groups are being trained in the UK and Finland.

Scientists believe that dogs, after training, acquire a specific odor produced by volatile organic compounds generated by catabolites, substances produced by the replication of the virus that escape the body through sweat.

During the testing period, the dogs did dozens of trials, with a success rate between 76% to 100%.

This is not surprising, as it is already known that dogs have a fantastic sense of smell.

Ao is estimated to be at least 10,000 times better than ours.
