A study reveals that there is no evidence that the muzzle protects against infection with corona
In a study published on the Danish website (The Local) reveals that there is no evidence that the muzzle protects the wearer from infection with corona, especially when it is found that the infection is transmitted through the air through the droplets emitted from the infected person when speaking or coughing and sneezing.
The local website stated that this study did not talk about whether the injured person who wears the muzzle protects others or not through this known preventive measure.
In it, a comparison was made between a group of people wearing masks, and another group that did not wear masks, and the results found that the group that persevered in wearing the muzzle was injured by 1.8%, while the group that did not wear the muzzle by 2.1%, which are very close.
Hence, the researchers in this study said that the muzzle offers a normal degree of protection ranging from 15 to 20%.
She said that her findings are not an incentive for people to stop wearing the muzzle, because the experiments that were conducted did not study the role of the muzzle when the affected person wears it and how this reflects on others.
According to the "Daily Mail" newspaper, researchers have warned of "weak" protection provided by some reusable masks.
The researchers downplayed the usefulness of some of these masks because they do not filter or "filter" only 7 percent of the harmful bacteria, which means that their efficacy is very limited, or completely non-existent.
