The U.S. Centers for Disease Control (CDC) has issued its latest guidelines on wearing masks to prevent the new coronavirus infection, the first time the center has held a conference call with reporters since the outbreak of the new coronavirus crisis in the U.S. in March,media reported. In addition, the guidance strongly encourages everyone to continue to wear masks in public, especially those attending large gatherings where individuals may raise the volume, shout or sing.
But officials may be starting to worry more about Americans becoming more lax about wearing masks. Experts also predict that the death toll will rise in the coming weeks and months, and that people may be able to remove their masks in public because they are now three voltdays.
But this is precisely the wrong move. Anne Rimoin, a professor of epidemiology at the University of California, Los Angeles and director of the Center for Global and Immigration Health at the University of California, said that if they can do so, people should try to avoid taking off their masks on the hottest days. At the same time, the effect of wearing a mask is related to its material. In response, Rimoin said, “Your ability to breathe through a substance is as important as your ability to stop the spread of the disease.” For example, cotton masks provide great comfort and ‘breathability’. Ideally, the professor noted, a mask should meet the requirements of being comfortable, adding that the shape of the mask should not be damaged after being cleaned and dried.
