Cloth masks, especially homemade ones, were supposed to be a stop-gap measure. But almost a year into the pandemic many Americans are still wearing them.

Marco Werman talks about why the United States is so behind at regulating the quality of masks with Zeynep Tufekci, a Turkish sociologist and writer at The University of North Carolina who has studied the effectiveness of different types of masks and written about it in The Atlantic.
