I remember that they were also saying that the general public doesn't have to worry about it too much. That it doesn't prevent the spread of the disease. It's only because medical people in hospitals are exposed so much.
Here's an article from Mar 31, 2020. Interestingly, it seems Trump was recommending masks for general use before the CDC and other experts.
THE CORONAVIRUS CRISIS
Should We All Be Wearing Masks In Public? Health Experts Revisit The QuestionA few months ago, it may have seemed silly to wear a face mask during a trip to the grocery store. And in fact, the mainline public health message in the U.S. from the Centers for Disease Control and Prevention has been that most people don't need to wear masks.
But as cases of the coronavirus have skyrocketed, there's new thinking about the benefits that masks could offer in slowing the spread. The CDC says it is now reviewing its policy and may be considering a recommendation to encourage broader use.
At the moment, the CDC website says the only people who need to wear a face mask are those who are sick or are caring for someone who is sick and unable to wear a mask.
But in an interview with NPR on Monday, CDC Director Robert Redfield said that the agency is taking another look at the data around mask use by the general public.
"I can tell you that the data and this issue of whether it's going to contribute [to prevention] is being aggressively reviewed as we speak," Redfield told NPR.
And Tuesday, President Trump weighed in suggesting people may want to wear scarves. "I would say do it," he said, noting that masks are needed for health care workers. "You can use scarves, you can use something else," he said.On Tuesday Dr. Deborah Birx, who serves as the White House's coronavirus response coordinator, said the task force is still discussing whether to change to the recommendation on masks...
...But there is still a big concern about mask shortages in the United States. A survey released Friday from the U.S. Conference of Mayors finds that about 92% of 213 cities did not have an adequate supply of face masks for first responders and medical personnel.
At this point, experts emphasize that the general public needs to leave the supply of N95 medical masks to health care workers who are at risk every day when they go to work.
And supplies are also tight for surgical masks, the masks used everywhere from dentists' offices to nail salons and that are even handcrafted.
"We need to be very mindful that the supply chain for masks is extremely limited right now," Gottlieb says. "So you really don't want to pull any kind of medical masks out of the system."
Given current shortages, it may be too soon to tell the general public to start wearing surgical masks right now. "We certainly don't have enough masks in health care," says William Schaffner, an infectious disease expert at Vanderbilt University. "I wouldn't want people to go out and buy them now, because we don't want to siphon them off from health care."Added link
