Dogs can stop the spread of COVID / Evidence has shown that they can track infected people

Tests with sniffer dogs have shown that they can track people infected with Covid, thus preventing the virus from spreading at a time when society will reopen.

Sniffing dogs are not a new thing. In various places they were used to smell bugs, mold or cancers. Dogs are now trained to distinguish a typical odor produced by the infected, a odor that the human nose cannot smell.

This advantage of dogs will come in handy when checking in airports or during mass activities. At Helsinki Airport in Finland dogs have been used for several months to test passengers who may be infected with Covid-19.
