Does sweat from someone infected with COVID-19 have a unique scent? Researchers in Paris, and elsewhere, believe it does—and we now know dogs can sniff it out. A new study from researchers at the national veterinary school in Alfort, outside Paris trained 8 Belgian Malinois shepherds to identify the smell of COVID-19 in the sweat of infected individuals. The dogs’ overall success rate was near-perfect, correctly guessing an average of 95% of samples. Four dogs successfully identified a positive COVID sweat sample 100% of the time.
