White House will urge all Americans to wear face coverings in public

By The Associated Press 6park.com
WASHINGTON — The Trump administration is formalizing new guidance to recommend that many, if not almost all, Americans wear face coverings when leaving home, in an effort to slow the spread of the new coronavirus. 6park.com
The recommendations, still being finalized Thursday, would apply at least to those who live in areas hard-hit by community transmission of the virus that causes COVID-19. A person familiar with the White House coronavirus task force's discussion said officials would suggest that non-medical masks, T-shirts or bandannas be used to cover the nose and mouth when outside the home — for instance, at the grocery store or pharmacy. Medical-grade masks, particularly short-in-supply N95 masks, would be reserved for those dealing directly with the sick. 6park.com

Trump on Tuesday indicated he would support such a recommendation, potentially even for all Americans regardless of where they live. “I would say do it, but use a scarf if you want, you know, rather than going out and getting a mask or whatever.” 6park.com
“It’s not a bad idea, at least for a period of time,” he added. 6park.com
A Centers for Disease Control and Prevention draft of the guidance would make the covering recommendation apply to nearly all Americans, all over the country, according to a federal official who has seen the draft but was not authorized to discuss it. 6park.com
Some exceptions would be young children under age 2, anyone who has trouble breathing or anyone who is unable to remove the covering without help. 6park.com
Officials were still discussing whether to limit its geographic scope. 6park.com

Under the previous guidance, only the sick or those at high risk of complications from the respiratory illness were advised to wear masks. The new proposal was driven by research showing that some infections are being spread by people who seem to be healthy. 6park.com
On Wednesday, Eric Garcetti, the mayor of Los Angeles, urged his city's 4 million residents to wear masks when they’re in public. 6park.com
In response to recent studies, the CDC on Wednesday changed how it was defining the risk of infection for Americans. It essentially says anyone may be a considered a carrier, whether they have symptoms or not. 6park.com
The virus spreads mostly through droplets from coughs or sneezes, though experts stress that the germ is still not fully understood. 6park.com
U.S. officials have been telling people to stay at home as much as possible, and keep at least 6 feet (2 meters) away from others when they do go out. Other advice includes frequent hand washing and not touching your face. 6park.com
But until now federal officials have stopped short of telling people to cover their faces out in public. 6park.com
Scientists can’t rule out that infected people sometimes exhale COVID-19 virus particles, rather than just when coughing or sneezing, but there isn’t enough evidence to show if that can cause infection, according to a committee convened by the National Academies of Sciences, Engineering and Medicine to advise the White House. 6park.com
The question has to do with whether the new coronavirus spreads mostly by droplets that don’t linger for long in the air, or also by tinier “aerosolized” particles. Certain medical procedures, such as inserting breathing tubes, can create those tiny particles, which is why health care workers wear close-fitting N95 masks during such care. 6park.com
The committee cited one study that detected airborne viral RNA in and just outside some hospital isolation rooms, but noted that it was unclear if that could infect someone. 6park.com
U.S. Surgeon General Dr. Jerome Adams has repeatedly admonished Americans not to wear face masks, saying they don’t prevent the people who wear them from catching the virus. He and other officials have stressed that surgical face masks and other protective medical equipment have been in short supply and must be prioritized for people such as health-care workers. 6park.com
The World Health Organization on Monday reiterated its advice that the general population doesn’t need to wear masks unless they’re sick. Since the epidemic began in China, the WHO has said masks are for the sick and people caring for them. 6park.com
“There is no specific evidence to suggest that the wearing of masks by the mass population has any particular benefit," WHO’s epidemic chief Dr. Mike Ryan said during a news conference. "In fact, there’s some evidence to suggest the opposite,” he added, noting risks from an improperly fitted mask or improperly putting it on or taking it off. 6park.com
That’s in addition to the problem that health care workers who do need masks are facing “a massive global shortage,” Ryan said. “The thought of them not having masks is horrific, so we have to be very careful on supply, but that is not the primary reason why WHO has advised against using masks.” 6park.com
Many people have taken it upon themselves to make their own masks, but one North Carolina health system found that such DIY products vary in how well they work. Wake Forest Baptist Health doctors and scientists tested 13 different designs made by community volunteers. They found that some were better at filtering than off-the-shelf surgical masks but others were barely better than wearing no mask at all. 6park.com
Separately, a 2013 study tested whether homemade masks might help during a flu pandemic. It found surgical masks were three times more effective in catching droplets from coughing people than masks made from cotton T-shirts, though it’s not clear if the new coronavirus behaves exactly like flu viruses. 6park.com
