Cruises in the United States could return by mid-July, according to a letter from the Centers for Disease Control and Prevention shared with the cruise industry.

The simulated sailings were initially part of the CDC's 'Conditional Sail' Order, and the agency had said earlier this month they could likely begin soon.

The new guidelines are also in line with the CDC's recommendation that all crew and guests should be fully vaccinated before boarding, as well as the agency's guidance that fully-vaccinated Americans can travel with low risk to themselves.

In addition to vaccines, the CDC said it would update its testing and quarantine protocols to reflect its guidance for vaccinated people, USA Today reported.
