While nasal and oral swabs are commonly used as means of testing for COVID, there’s yet another body part that may provide insight into whether or not you’ve contracted the virus. A new study reveals that dogs may be able to sniff out COVID somewhere else on the human body. Read on to discover where else indications of COVID might be lurking.

According to a Dec. 2020 study published in PLOS One, trained dogs can actually detect coronavirus in humans by sniffing sweat from their armpits. In the study, 177 individuals—95 of whom had symptomatic cases of COVID-19 and 82 of whom neither tested positive for COVID-19 nor had symptoms of the virus—had their underarm sweat tested by a group of six dogs trained in scent-based detection. Three of the dogs involved in the study had been trained to sniff out explosives, two were trained in colon cancer detection, and one had been trained as a search and rescue dog.
The dogs were then trained to detect COVID by smelling a COVID-positive sweat sample and subsequently being asked to sniff out the same scent in a randomized lineup of COVID-positive and COVID-negative underarm sweat samples. To indicate the presence of COVID, the dogs were trained to sit in front of the positive samples. Among the group of six dogs trained to do so, accuracy rates for sniffing out COVID ranged between 76 percent and 100 percent.
Based on these findings, the study’s authors concluded that, in areas of the world where an insufficient supply of medical tests for COVID is available or access to said testing is limited, “exploring the possibility of using dog olfactory detection as a rapid, reliable and cheap ‘tool’ to pre-screen people or perform rapid checking in certain circumstances is important.” However, there are countless other indicators that you might have the virus—read on to discover which subtle symptoms may indicate you’re COVID-positive.
