[Ed. – Good dog!]
Dogs can be trained to detect more than 90 percent of Covid-19 infections even when patients are asymptomatic, according to research published Monday, which authors hope could help replace the need to quarantine new arrivals.
Using their remarkable sense of smell — which can pick up the equivalent of half a teaspoon of sugar in an olympic-sized swimming pool — dogs have already shown that they can sniff out maladies such as cancer, malaria and epilepsy.
Several previous studies have shown proof-of-concept that dogs can detect SARS-CoV-2.
Researchers from the London School of Tropical Medicine wanted to see if dogs could detect a distinctive odour given off from chemical compounds associated with someone who is Covid positive but doesn’t show symptoms.
They gathered samples of clothing and face masks from people who had tested positive for mild or symptomatic SARS-CoV-2.
