In an amazing breakthrough, six Labrador Retrievers in Thailand have been trained to detect Covid-19 patients by simply sniffing them out.
Research carried out at the Chulalongkorn Veterinary Faculty over six months has since proven to be 95 per cent accurate, and the dogs can even sniff out asymptomatic patients.
According to Prof. Kewali Chatdarong, who heads the project, dogs have a 50 times better sense of smell than humans and they decided to capitalise on this.
The dogs do not even need to sniff the people directly and can detect the virus merely through their sweat samples.
“When the dog sniffs a sample that contains the Covid-19 virus, it will immediately sit down.
“The entire process is completely safe for the dogs and poses no danger to them,” said Kewali.
Six dogs will be placed at airports and ports and each dog only take one to two seconds to detect the virus.
Kewali said they hope to train more dogs in the future to detect other health issues, such as malaria, depression, diabetes and Alzheimer’s disease.
Similarly, in countries such as Finland, Germany, France, and Australia, dogs have also been trained to detect the virus with an accuracy of 94%.
