The move broadens the category of masks that doctors and nurses are approved to use in a healthcare setting. "The FDA and CDC's action to allow a wider range of respirators to be used in healthcare settings will help those on the front lines of this outbreak and their patients, which will keep all Americans safe," HHS Secretary Alex Azar said. "We will continue pursuing every possible avenue to secure the protective gear needed for responding to the COVID-19 outbreak." —Feuer
