DUBAI—Police in Dubai have built up a special unit of 38 sniffer dogs that can detect COVID-19 from human sweat samples with 92 percent accuracy, the supervisor of the training program told Reuters.
Dubai Police trained the cohort, which includes German Shepherds, Labradors, Cocker Spaniels and Border Collies, to recognize the scent of COVID-19 using samples of sweat from people with confirmed infections, collected by holding a swab in an armpit for a few minutes.
