Cronay dogs come to the aid of humans!

Trained dogs are as reliable at diagnosing COVID-19 as laboratory tests and may detect infected and asymptomatic individuals even better than PCR tests. . The researchers reported in the June 1 issue of PLOS One that examining the sweat samples of 335 people (who had undergone PCR!) By Cronaia dogs (by sniffing) showed that 31 cases in a population of 192 had Covid disease. They were. In other words, 97% of people with coronavirus who were diagnosed with PCR and had no symptoms were identified by the sniffing of dogs. src="https://bingmag.com/picsbody/2206/20725-2.jpg" alt="BingMag.com Cronay dogs come to the aid of humans!" loading="lazy">

In general, there is evidence that dogs can be very effective for mass screening in places such as airports or concert halls, and may even They are a more convenient alternative to individual experiments using nasal swabs. It is interesting to note that researchers have found that dogs' noses have the ability to detect more COVID-19 cases than antigen tests. In addition, evidence suggests that dogs can detect asymptomatic and involved cases (positive result) up to 48 hours before the PCR test.

In this study, dogs from French fire stations and the Ministry The UAE received training (toys and usually tennis balls) to be diagnosed with the corona virus. Scientists in this field acknowledge that depending on the dog's experience in detecting odors, it takes about three to six weeks for the dog to be trained to detect COVID-19 cases from sweat samples! In this study, dogs sniffed cone-shaped containers of sweat samples collected from the armpits of volunteers; Of course, using sweat on the back of people's necks or smelling used masks are also good examples for dogs. Kenneth Furton, a forensic chemist at the International University of Florida in Miami who did not participate in the study, says the results show that odors from multiple areas of the body can be used for screening. He used dogs. It should be noted that similar results to the smaller statistical population are consistent with these studies.

Other research has shown that dogs perform as well or even better than PCR tests to detect the COVID-19 virus. Forton acknowledges that one of the biggest advantages of using dogs over other experiments is their high speed of detection. The speed scale means that other tests only show results in about 10 minutes, while Crony dogs can detect the patient in seconds or even a fraction of a second.

Cynthia Otto The director of the Center for Trained dogs at the University of Pennsylvania School of Veterinary Medicine says that it is not clear exactly how dogs smell when they are diagnosed with Covid 19 or other diseases, as not just one chemical is involved! Rather, it may be a pattern of increasing and decreasing levels of various chemicals, a factor in the diagnosis of disease by dogs. Simply put, it is not possible to make an extract of the smell of covidium and use it to diagnose the disease. Is! Of course, some doctors, scientists, and government officials are skeptical of these claims, despite repeated studies showing that dogs can detect cavid! This suspicion is not very acceptable for researchers in this field, because dogs have already been used and tested to detect drugs, explosives, and other diseases such as cancer. "Every time you go to the airport, because the dogs sniff your luggage and find no explosives, you trust them and get on the plane, but you're not interested in trusting them to diagnose the cuvette?">

Challenges of Cronaa dogs

In general, one of the challenges of Croonai dogs is that people do not consider them as reliable as electronic sensors. But you should know that dogs can be one of the most advanced biological sensors instead of electronic sensors. Another challenge is to train such dogs, which is certainly time consuming!

At present, there are not even enough trained dogs to diagnose drugs and explosives, so training dogs to diagnose diseases is also a big challenge. ! On the other hand, dogs that perform well in educational and laboratory settings may not perform well in public or community settings.
