Trials are taking place in the UK to see whether specially trained airport sniffer dogs could detect Covid-19 in travelers, even before symptoms appear.
Sniffer dogs are already a common sight in airports -- usually, they're looking out for drugs, weapons or other contraband.
Researchers from the London School of Hygiene and Tropical Medicine, in collaboration with charity Medical Detection Dogs and the UK's Durham University, say respiratory diseases change body odor, and they reckon trained dogs will be able to pick up this shift on Covid sufferers.This preliminary trial has recruited six dogs, dubbed"The Super Six" -- they're all either labradors or cocker spaniels.
They're getting subjects to wear face masks for a few hours. Then the masks are passed on to the dogs, and used to help the animals distinguish between different scents."Which is a bit strange," admits Lindsay."But we've known from our previous experience that this is a really good way of collecting odors from people and it's such an easy way to do it.
