To mask or not to mask

Recent study from the School of Mathematical and Statistical Sciences published in the Journal of Infectious Disease Modeling:

"People can spread COVID-19 to others, even if they don’t feel sick. Wearing a face covering over the nose and mouth can be effective in protecting other people in case the wearer is affected but doesn’t show symptoms. If the wearer is healthy, a face covering also helps to prevent them from being infected by others."

"The team performed simulated case studies using mortality data compiled by Center for Systems Science and Engineering at John Hopkins University from Jan. 22, 2020, through April 2, 2020, for New York and Washington state. The case studies again showed that mass adoption of even poor quality homemade masks has a positive benefit. [...] The researchers emphasize that masks should not be viewed as an alternative but as a complement to other public health control measures including social distancing, consistent hand-washing, self-isolation, etc."
