Chile police train dogs to sniff out COVID-19 patients

The dogs are being trained to detect carriers of COVID-19 by identifying a smell metabolic changes cause in their body.

A new, simple and reportedly 95-percent accurate method of detecting carriers of COVID-19 is expected to make its debut in Chile.

Police dogs there are being trained to identify people who are infected, even in the earliest stages of the disease.
