British scientists said today, Monday, that police dogs that have been trained to use the smelly socks worn by people with Coronavirus can be used soon in airports or places of collective gatherings to find out about Corona infection "the smell of Corona" for people with the virus, according to Reuters. .
Scientists said that dogs trained to know Corona infection, which work in teams of two people, can scan a row of several hundred people coming from the plane within half an hour, for example, and detect up to 94.3% of the infected.
Presenting the results of an early-stage study, which included about 3,500 samples of the scent donated in the form of unwashed socks or shirts worn by members of the public and health workers, the researchers said dogs were even able to smell asymptomatic or mild, in addition to emergent cases. About a mutant variant that appeared in the United Kingdom late last year.
"Dogs can be a great way to quickly screen a large number of people and prevent the return of Coronavirus to the UK," said Steve Lindsay, a professor in the Department of Biological Sciences at Dor Ham University who worked on the study.
James Logan, a disease control specialist at the London School of Hygiene and Tropical Medicine who led the project, said the main advantage of sniffer dogs over other examination methods is their "impressive speed and good accuracy among large groups of people".
The British research, which was published online on Monday before it was peer-reviewed, adds to other pilot projects in Finland, Germany, Chile and elsewhere that are testing sniffer dogs trained on the Coronavirus at airports.
Reuters said that dogs were trained in the UK study over a period of several weeks by providing 200 samples of smell from people who had tested positive for the Coronavirus, in addition to 200 control samples from people whose test results were negative.
The highest performing dogs in the experiment detected the smell of the Corona virus in the samples with a sensitivity of 94.3%, which means a lower risk of false negative results, which means a lower risk of false positive results.
Logan's team said that this accuracy is higher than what is recommended by the World Health Organization to diagnose Corona, as dogs outperformed other tests, which have an overall sensitivity of between 58% and 77%.
Lawrence Young, a virologist and professor of molecular oncology at the University of Warwick, added: "This evidence indicates that trained dogs can be used in places such as airports, sports stadiums and concert venues to detect corona.
The agency asks whether this method will work in the real world on people rather than samples from socks and shirts.
