Dogs have smell receptors up to 10,000 times more powerful and accurate than humans. That allows certain trained dogs to sniff out diseases like cancer, malaria and viral infections.

A new study, which was piloted by the University of Veterinary Medicine Hannover, the Hannover Medical School and the German Armed Forces found that, if properly trained, dogs were able to discriminate between human saliva samples infected with SARS-CoV-2 and non-infected samples with a 94% success rate overall.
The hope is this method of detection could be one day be used in public areas such as airports, sporting events and other mass gatherings (in addition to laboratory testing) to help prevent future Covid-19 outbreaks, according to researchers.
