Study suggests trained dogs can sniff out coronavirus with up to 94% accuracy

Dogs possess an extraordinary sense of smell, with up to 350 million sensory receptors compared to humans' 5 million. This allows them to detect substances in incredibly small quantities, such as a teaspoon of sugar in two Olympic-sized swimming pools. Their remarkable olfactory abilities make them valuable in detecting human diseases by odor. While not a replacement for PCR or lateral flow tests, dogs can complement these methods in environments like airports and workplaces, screening up to 300 people per hour.
