Can sniffer dogs really detect COVID almost as well as a PCR test? Turns out they can

"Dogs have an exceptional sense of smell. We take advantage of this ability in
many ways, including by training them to find illicit drugs, dangerous goods
and even people.

In recent years, a dog’s sense of smell has also been used in the medical
field. These remarkable animals can be trained to sniff out cancer, diabetes,
and extraordinarily, epileptic seizures before they occur.

Early in the pandemic the possibility of using dogs to sniff out COVID was
explored in a few countries. And although the results of these early trials
surpassed most people’s expectations, many questions remained. These included
how well these findings would stand up to more rigorous scientific scrutiny and
how well dogs would perform outside the artificial environment of the research

In the past week we have moved closer to answering these questions, with an
article published in BMJ Global Health, which found dogs could detect COVID
almost as well as PCR tests, in some circumstances."
