Masks help stop the spread of coronavirus – the science is simple and I'm one of 100 experts urging governors to require public mask-wearing
Recommendations around mask usage are confusing. The science isn't. Evidence shows that masks are extremely effective to slow the coronavirus and may be the best tool available right now to fight it.
There are numerous studies that suggest if 80% of people wear a mask in public, then COVID-19 transmission could be halted. Until a vaccine or a cure for COVID-19 is discovered, cloth face masks might be the most important tool we currently have to fight the pandemic.
Given all of the laboratory and epidemiological evidence, the low cost of wearing masks – which can be made at home with no tools – and the potential to slow COVID-19 transmission with widescale use, policymakers should ensure that everyone wears a mask in public."
"While all models have limitations and are only as good as their assumptions, this one is “a very thorough model and well done,” said William Schaffner,an infectious disease specialist at Vanderbilt University, who reviewed the De Kai team’s paper. “It supports a notion that I advocate along with most other infectious disease experts: that masks are very, very important.” Jeremy Howard, founding researcher at fast.ai and a distinguished research scientist at the University of San Francisco, also assessed the paper.
