President Donald Trump on Thursday released guidelines for reopening the American economy as the U.S. recovers from the COVID-19 outbreak.

The guidelines propose a phased reopening, allowing some states to begin efforts to resume normal economic activity as early as April 17. Such states that do begin at such a date should have widespread, efficient testing capabilities and sufficient or excess healthcare capacity to handle a potential surge in cases, should that arise.

Additionally, the guidelines recommend that the states themselves reopen in stages instead of all at once. Governors have been delegated the authority to begin phased openings at the statewide or county-by-county level.

The guidelines recommend that large venues should continue to adhere to strict physical distancing protocols.

In those areas with no evidence of the virus resurging after two weeks of reopening, nonessential travel may resume.
