Robert Redfield, director of the U.S. Centers for Disease Control and Prevention (CDC), said this week that to stop the spread of the new coronavirus, all Americans need only do one thing: wear masks,media bGR reported. Redfield and other health officials made the request in a new scientific editorial. Redfield believes that if every American follows this rule, the new crown outbreak will be under control within two months.
Redfield explained that according to the latest data, masks are an effective way to prevent new infections. He also believes that if wearing masks is a common practice across the United States, the deadly crisis will be resolved in about eight weeks.
“Covering the mouth and nose with filtermaterials has two purposes: personal protection against inhalation of harmful pathogens and particulate matter; source control to prevent exposure to infectious microorganisms that may be discharged during breathing.” Redfield and other health officials explained in the article.
“When asked to wear a mask, a lot of people think about it in terms of personal protection. But masks are also widely and routinely used as source control. For example, if we were allowed to choose between a team that didn’t wear some occlusion on our mouth and nose and a team that wore a shield, almost all patients would reject the former. This option seems absurd because it is well known that the use of masks in this case reduces the risk of infection at the surgical site caused by microorganisms produced during conversation or breathing by the surgical team. Masks play a similar role in blocking the spread of SARS-CoV-2. “
