From the Introduction: "On April 16, 2020, the President unveiled 'Opening Up America Again' Guidelines, a three-phased approach to reopening based on the advice of public health experts. These Guidelines are helping State and local officials reopen their economies and get people back to work, while protecting the health and safety of the American people. This Blueprint is designed to facilitate State development and implementation of the robust testing plans and rapid response programs called for in the President's Guidelines. Having these plans and programs in place will help States prevent and contain local outbreaks that may occur as economic and social activities expand across the country."
