Four Maui dogs have been found to have COVID-19, according to a study using emerging canines to fight the pandemic. In a proof-of-concept study published yesterday, they were trained to recognize COVID 19 from human sweat. Four dogs from the University of Hawaii School of Veterinary Medicine in Honolulu, Hawaii, were trained to detect COVID-19, a deadly form of the human infectious disease, by smelling human sweat in a proof-of-concept study published today. Thursday.
The four, all from Maui, detected COVID-19 in their blood, urine and sweat as part of a study dedicated to an emerging "science of dogs" to combat pandemics. A dog has been trained in Hawaii to detect COVID19 by the smell of sweat in humans, according to proof-of-concept studies published yesterday.
In a study published Thursday, they were trained to recognize Covid 19 from human sweat. In a proof-of-concept study published Thursday by the University of Hawaii School of Veterinary Medicine in Honolulu, Hawaii, four dogs from UH - Mauna Kea, Maui - trained their dogs to detect COVID-19, a deadly form. of human infectious disease, smelling human sweat, proof-of-concept studies published Thursday showed.
For the study, which began in March, the researchers recruited six dogs that had been previously trained to sniff out bombs and colon cancer and that had been used in search and rescue missions. A total of six sniffing dogs participated in the test and had to be retrained in the recognition of COVID-19.
Additionally, bomb-sniffing dogs were trained to detect 30 to 40 different types of explosives and could work with multiple people rather than sniff each one individually. Since sniffer dogs are sensitive to the odor of the coronavirus, handlers kept the animals in line with humans by checking many objects at once rather than sniffing out explosives as usual.
The dogs also had to be retrained in the management of scent lines, that is, in distinguishing between smells, as they had been trained to recognize the general human scent by focusing on diseases, such as smells.
If future studies can show that their sense of smell is so sensitive to COVID-19 and other diseases, national authorities might consider using their trained sniffer dogs to quickly monitor large groups of people.
The short training period can also be explained by the fact that the test dogs were already well trained. Travelers may already see specially trained dogs at airports, but researchers are still trying to prove beyond a reasonable doubt that they can absorb odors before the method is fully adopted and rolled out internationally.
Travelers may have seen specialized dogs at an airport, and researchers are still trying to prove beyond reasonable doubt that dogs can select scenes before the method is fully adopted and spread internationally.
Also researchers from the University of Helsinki School of Veterinary Medicine are training dogs to detect COVID 19 since early 2020. Medical Detection Dogs has already worked with LSHTM and Durham University to successfully demonstrate that they can be trained to detect malaria . The new study will study training a dog with a mix of Labradors, Cocker Spaniels and humans to detect coronaviruses in humans, even when they show no symptoms.
The research involves training six available organic sniffing dogs to distinguish between positive and negative scent samples taken from 3.250 asymptomatic adults independently tested for COVID 19 infection. Samples are delivered serially and if the dogs detect COVID 19, they can be trained as sedentary"says Maurer.
The test is then double blind and the dogs are not aware of the level of the Covid 19 samples. It takes a few weeks for each dog to sniff out COVID 19 carriers, but according to scientists, this has proven to be very effective.
The dogs were trained not only to detect the scent from a distance, but also to protect the person to be controlled and the handler from it, since there are trainers for each of the sniffer dogs. According to Maurer, the risk for dogs is very low, with a risk of infection of only 0,5% and a mortality rate of 1,2%.
