Dogs have been people’s favorite friends for ages. They never put a smile on their face by doing cute little things, whether they’re begging for food, or forcing you to take them out for a walk, the dogs are -residence for the man. Dogs can not only sniff their medication but also COVID-19. According to a new study, dogs with Coronavirus training can detect it 94% of the time. And interestingly they can do it faster and more accurately.

Tommy Dickey of the University of California, Santa Barbara in the USA is also part of the research. He said, “The most interesting finding is that studies have already shown that dogs can identify people who are positive about Covid-19. Not only that, they can do it unobtrusively, faster, and with relative accuracy or perhaps better than our conventional validation tests. ” Also read – As revenue loses, Delhi Metro Center urges trains to run at full seating capacity
“Twice one dog twice reported positive results that could not be confirmed. Two weeks later they found out that the two people who took these samples had to go to the hospital with Covid, ”said Dickey.

The magic lies in the canine sense of smell, which allows dogs to find molecules in tiny clusters – “one part in a rectangle compared to one part in a billion humans,” according to the paper published in the Journal of Osteopathic Medicine.
Further, with 125-300 million olfactory cells and a third of their brains defining odors, dogs are well equipped with the ability to sniff out the volatile organic fertilizers that are marking Covid ‘s presence, the researchers said.
Although the virus itself has no odor, metabolic results emitted by Covid individuals through their sweat glands were detected by the 18 dogs selected for the study with an accuracy level of 83- 100 percent after just four days of training.
Meanwhile, a German research group was employing eight sniffer detection dogs in a randomized, double-blind, controlled pilot study. The group trained the dogs for a week and then sent them to sniffing 1,012 samples of saliva or tracheobronchial secretions.
They returned an average detection rate of 94 percent with a sensitivity (highly advanced detection ability) of 67.9 percent to 95.2 percent and a specificity (very negative detection ability) of 92.4 percent to 98.9 percent.
