Dogs can sniff out 90% of COVID-19 cases, even if they're asymptomatic [View all]
According to new research, trained dogs are capable of identifying 90% of COVID-19 infections regardless of whether those cases are asymptomatic.
A team of scientists from The London School of Hygiene & Tropical Medicine, a public research university based in London, are behind the research, which is currently available to read as a pre-print. The results add to growing evidence that dogs can sniff out the virus, echoing previous research and a recent French study, released seven days ago, that found dogs were able to identify the virus with 97% accuracy.
In the new tests, scientists used the socks of 200 COVID-19 patients, doling them out to six poor dogs who were tasked with sniffing them, alongside others, in an attempt to figure who did and didn't have COVID-19.
Dogs have over 220 million scent receptors (in comparison, humans have 5 million) and are over 100,000 times more accurate at identifying scents. Their noses are capable of smelling substances at a concentration of one drop in three Olympic-sized swimming pools. This has allowed dogs to successfully sniff out multiple different types of cancer, alongside other diseases like malaria and Parkinson's.
