The risk for cruise travelers was lowered by the CDC from high to moderate.

Since the beginning of the Pandemic, the CDC has issued a level 2 for cruise travel.

The CDC advises travelers to be up to date with their Covid-19 vaccines before they embark on a cruise, and warns those who are not up to date with their vaccinations to avoid cruises.

Even if you are up to date with your Covid-19 vaccine, the chance of getting Covid-19 on a cruise ship is moderate.

Guests should wear masks outside of their cabins, according to the CDC.

The agency advises travelers to check the color code of their ship to see how many cases have been reported and to check their vaccination status. Travelers should take a Covid test three to five days after their cruise.

The cruise industry had argued that cruise ships were being unfairly targeted by the warning level. When the CDC issued a Level 4 notice in December during the rise of the omicron variant, CLIA called it "perplexing." The number of cases identified on cruise ships was argued to be a slim minority of cases, taking up little medical resources.

The cumulative number of new Covid-19 cases among crew members over the past 14 days is the primary factor used by the CDC to determine traveler's threat level.

The threat level must be between 500 and999 cases. There were between 1,000 and 2,000 new Covid-19 cases in Level 3. Over the course of 14 days, more than 2,000 cumulative new Covid-19 crew cases were counted.
