The coronavirus pandemic worsens and cases rise in separate parts of the world owing to fresh waves, a new detector has come around sniffer dogs. A new study shows that sniffer dogs can be trained to identify people with the SARS-CoV2 virus by their odor. Researchers at the London School of Tropical Medicine, who presented a new study, said that these dogs could soon be used at airports or mass gathering venues to pick up the “corona odor” of Covid-19 infected people. Working in teams of two, the Covid-trained dogs could screen a line of several hundred people coming off a plane within half an hour and detect with up to 94.3 percent sensitivity those infected. The study involved 3,500 odor samples donated in the form of unwashed socks or T-shirts worn by the public and healthcare workers. Researchers said that the dogs were even able to sniff out asymptomatic or mild Covid-19 cases, as well as cases caused by a mutant variant that emerged in the UK. The samples of the socks were arranged in lab tests for six dogs that had been trained to indicate either a presence or absence of the chemical compound. dogs have previously shown that they can sniff out diseases such as cancer, malaria, and epilepsy. The dogs use their remarkable sense of smell which can pick up the equivalent of half a teaspoon of sugar in an Olympic-sized swimming pool. Source:(Internet)
