NEW YORK (AP) — U.S. health officials on Friday encouraged more Americans to wear the kind of N95 or KN95 masks used by health-care workers to slow the spread of the coronavirus.

Those kinds of masks are considered better at filtering the air. But they were in short supply previously, and Centers for Disease Control and Prevention officials had said they should be prioritized for health care workers.
