Published 24 June 2020

Late last week, a group of researchers posted a letter that they had sent to the Proceedings of National Academy of Sciences (PNASrequesting the retraction of a study published the week before that purportedly showed mask use was the most effective intervention in slowing the spread of COVID-19 in New York City. Stephanie Soucheray writes for CIDRAP that though PNAS editors have yet to respond to the request, scientists have roundly criticized the study’s methodology, and the entire kerfuffle has highlighted the difficulty of “doing science” amid a full-blown pandemic.
