Sniffer dogs are being specially trained to detect people that are infected with Covid-19 who are not exhibiting symptoms.
These dogs will soon be sent to international airports and seaports to help identify asymptomatic cases among arrivals from abroad.
According to the Chula Journal website, the six Labrador retriever dogs, trained by a research team at the Veterinary Faculty of Chulalongkorn University, have a 94.8% accuracy in detection.
However, dogs’ noses are 50 times more sensitive than humans and can detect asymptomatic cases through their sweat.
