Masks significantly reduce infection risk, says new study
Requiring the wearing of masks in areas at the epicentre of the global coronavirus pandemic may have prevented tens of thousands of infections, a new study suggests.
Mask-wearing is even more important for preventing the virus's spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the United States of America.
Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest-hit areas of the world by the health crisis - the study found.
"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.
