People sometimes call infectious disease doctors “medical detectives”; They dive deep into a patient’s history and test results to solve the puzzle of why someone is sick. But what if dogs are the true sleuths of medicine? Studies show that dogs can detect COVID-19 better than many tests can. Their extraordinary sense smell allows them to sniff out the virus more quickly and accurately than laboratory and at-home tests. This superhuman ability is thanks to their 125 to 300 million olfactory cells, which is 120 million more than humans have in their nasal cavity! Even though researchers have long known about dogs’ talent for finding disease, the COVID-19 was the first time this skill was put to use on a larger scale.
