Dogs have been used for decades to sniff out drugs, bombs, dead bodies, and even cancer but now a team of British researchers are hoping their keen sense of smell can help detect COVID-19.
The London School of Hygiene and Tropical Medicine is working with specially trained dogs to develop a new kind of COVID-19 test, one that doesn't require a swab but rather just a sniff.
The organization recently discovered canines can detect malaria in humans and they are now investigating to see whether the same is true for COVID-19.
They say this would not replace traditional testing but rather it would act as a supplemental tool in the fight against COVID-19.
The dogs could be used at airports or other public areas to help prevent another outbreak once the current pandemic declines.
