Dogs can smell human sweat and diagnose Covid-19 even higher than PCR tests, a recent scientific study has shown. It is stated that this discovery will be groundbreaking in limiting the Covid-19 pandemic.
According to French research, dogs have a 97% accuracy in diagnosing Covid-19 by smelling human sweat. The accuracy of identifying negative people is 91%. These rates are better than PCR tests, which work in 15 minutes and are widely used.
In research conducted at the French National Veterinary School in Maisons Alfort, near Paris, sweat samples from the participants’ armpits were sealed in jars with cotton pads and had at least two different dogs sniffed. None of the nine dogs involved in the experiment had a previous relationship with people who gave sweat samples. Of the 335 participants, 109 tested positive for Covid-19 to form the control group. The researchers did not know which sample was positive during the experiment, in terms of objective results.
In addition to dogs sniffing bombs and drugs, virus-sniffing dogs are also expected to be used especially at airports, train stations, and other crowded areas. In this way, those who carry the virus can be detected very cheaply, in less than 1 second, and without disturbing the patient.
Dogs, which are people’s best friends, are fighting against the virus with us in the Covid-19 pandemic, just as they are with us in almost all disasters.
