Can Dogs Smell COVID? Here’s What the Science Says

November 23, 2020

(Nature) – Around the world, canines are being trained to detect the whiff of COVID-19 infections. Dog trainers are claiming extraordinary results — in some cases, they say that dogs can detect the virus with almost perfect accuracy. Scientists involved with the efforts suggest that canines could help to control the pandemic because they can screen hundreds of people an hour in busy places such as airports or sports stadiums, and are cheaper to run than conventional testing methods such as the RNA-amplification technique PCR.
