Masks

The debate over masks’ effectiveness in fighting the spread of the coronavirus intensified recently when a respected scientific nonprofit said its review of studies assessing measures to impede the spread of viral illnesses found it was “uncertain whether wearing masks or N95/P2 respirators helps to slow the spread of respiratory viruses.”

Now the organization, Cochrane, says that the way it summarized the review was unclear and imprecise, and that the way some people interpreted it was wrong.

“Many commentators have claimed that a recently updated Cochrane review shows that ‘masks don’t work,’ which is an inaccurate and misleading interpretation,” Karla Soares-Weiser, the editor in chief of the Cochrane Library, said in a statement.
