"Face Masks Really Do Matter. The Scientific Evidence Is Growing.
New research suggests that face coverings help reduce the transmission of droplets, though some masks are more protective than others"
"Face masks are emerging as one of the most powerful weapons to fight the new coronavirus, with growing evidence that facial coverings help prevent transmission—even if an infected wearer is in close contact with others.
"Robert Redfield, director of the Centers for Disease Control and Prevention, said he believes the pandemic could be brought under control over the next four to eight weeks if “we could get everybody to wear a mask right now.” His comments, made in mid-July with the Journal of the American Medical Association, followed an editorial he and others wrote there emphasizing “ample evidence” of asymptomatic spread and highlighting new studies showing how masks help reduce transmission.
"... . An analysis published in July in the BMJ, a medical journal, found that face coverings are now recommended or mandated in 160 countries to reduce coronavirus transmission.
