Experts, medical professionals — even Nobel Prize winners — are urging governors in an open letter to mandate that anyone in public or at work wear masks and face coverings to prevent spreading Covid-19.
A recently published, peer-reviewed study is recommending that all governments mandate wearing face masks and face coverings in public. The coverings limit the spread of coronavirus by limiting the spread of respiratory droplets.The CDC has been urging Americans to wear masks and face coverings in public since April 3. Many states are not requiring it, and some are requiring employees wear them at work. President Trump, announcing the CDC guidance that day, noted it was voluntary.
"It doesn't matter too much what [people] cover with: a paper towel, a bandana or a scarf, or a sewn-cloth mask," Jeremy Howard, one of the letter's authors, told CNN's Brianna Keilar on Thursday."Pretty much anything does a great job of dropping or blocking the droplets on the way out."Howard, a distinguished research scientist at the University of San Francisco, says blocking the droplets is critical.
