　　The national emergency caused by the coronavirus disease 2019 (COVID-19) outbreak in the United States continues to pose a grave threat to our health and security. As of April 29, 2021, the United States had experienced more than 32 million confirmed COVID-19 cases and more than 570,000 COVID-19 deaths. It is the policy of my Administration to implement science-based public health measures, across all areas of the Federal Government, to act swiftly and aggressively to prevent further spread of the disease.
