Dogs trained to detect the novel coronavirus have already begun sniffing passenger samples at airports in the United Arab Emirates and Finland.
A study recently found dogs can identify infected individuals with 85 per cent to 100 per cent accuracy and rule out infection with 92 per cent to 99 per cent accuracy.
Chile’s Carabinero police trained the dogs and Inspector General Esteban Diaz said dogs have more than 3 million olfactory receptors, more than 50 times those of humans, so were uniquely placed to help fight the coronavirus.
Infections in Chile are far down from a peak in June but have begun rising again with about 2000 new cases on average reported each day, according to a Reuters tally. Chile has a total of 589,189 confirmed cases and 16,217 deaths from the disease.
