The agency's rating, which was just bumped down to Level 2, still recommends all passengers be vaccinated before boarding a ship. "Getting vaccinated is still the best way to protect yourself from severe disease, slow the spread of COVID-19, and reduce the number of new variants," the CDC says. A warning Level 2 is "moderate," a significant downgrade from last year's Level 4 (the highest danger level) when the CDC told passengers to avoid embarking on a cruise ship altogether, regardless of their vaccination status. The CDC had previously lowered its warning to a Level 3 in February.

Tests are still taking place three to five days before cruise start dates, regardless of a passenger's vaccination status. If a passenger does test positive at any point, they are recommended to "isolate" and to keep track of their symptoms. In the March 14 update, the CDC also made some recommendations for travelers, including wearing "a well-fitting mask to keep your nose and mouth covered when indoors (outside of your cabin) or in crowded outdoor settings." Cruise companies halted all sailings in the Caribbean in spring 2020 as the pandemic took hold in North America. The CDC first issued a no-sail order on March 14, 2020 that was intended to stay in place for 30 days. At the time, several cruise ships across the world had become sources of major coronavirus outbreaks and subsequent deaths, including off the coast of Japan, Panama and Oakland, California.

The framework uses three metrics to determine the "community levels" of the virus: New COVID-19 hospitalizations, hospital capacity and new coronavirus cases. After the update, most U.S. states, including California, Illinois, New York and Texas no longer have mask mandates. According to U.S. News, the U.S. states and territories that still have mask mandates are Guam, Hawaii, Puerto Rico and the U.S. Virgin Islands.
