Scientists from the University of Copenhagen and the Danish National Hospital found that wearing a medical mask reduces the risk of contracting coronavirus by 15-20%. The team came to this conclusion during the study, its results were published on the website of the medical institution.

The study was carried out with the participation of 6,024 adult Danes, who were supposed to spend three hours every day in crowded places: one half wore masks, and the other did not.. A month later, it turned out that in the first group, 1.8 percent of volunteers were infected with the coronavirus, and in the second - 2.1 percent..

Scientists noted that the experiment was carried out back in April - May, when the Danes were recommended to wear personal protective equipment only in medical institutions, therefore, the data obtained show the degree of protection of personal protective equipment in conditions where most people do not comply with the mask regime.

In another scenario - when all people follow the mask regime - the risk of contracting coronavirus should be lower.
