If you’re like most Americans, there’s a good chance you’re going to wear a cloth mask today. Doing so makes sense. It remains the official recommendation in the United States, and it is something we’ve both advocated since the beginning of the pandemic. Both of us wrote articles as far back as March urging people to wear homemade cloth masks. We’re also the authors [along with 17 other experts] of a paper titled “An Evidence Review of Face Masks Against COVID,” which was just published in peer-reviewed form in the Proceedings of the National Academy of Sciences. But it’s past time for better solutions to be available to the public.

We first released the paper as a preprint back in April, and it took nine months to go through peer review. We’re happy that it’s published but, to be honest, we’re also deeply disappointed that it’s still relevant. We’d hoped that by 2021 supply chains would have ramped up enough to ensure that everyone had better masks. Cloth masks, especially homemade ones, were supposed to be a stopgap measure. Why are so many of us still wearing them?
