With the increase in prices around the world to prevent Corona virus, the World Health Organization revealed, on Saturday, a myth related to medical muzzles. The organization stressed, through its official account on the site "Twitter", that "it is not recommended that healthy people wear masks, and it is advised to wear them only when caring for a person suspected of infection (Covid-19)."

She also indicated "the need to wear a muzzle when coughing or sneezing," stressing that "the muzzle is effective only when used with washing hands regularly with soap and water or rubbing them with an alcohol antiseptic."
