Dogs have long been used for their highly sensitive noses, like sniffing out drugs and cancer, explosives and natural disasters.
Now, a charity organization in England is shifting their focus from training dogs to sniff out malaria to training them to identify those infected with COVID-19. The goal would be to identify carriers of the disease, even those who are asymptomatic.
This could help prevent further outbreaks after we have flattened the curve and eased up on quarantines and social distancing. A COVID-19-sniffing dog at an airport could, theoretically, smell someone with the disease, preventing the disease from travelling and reigniting the pandemic again.
