(CNN) — The US Centers for Disease Control and Prevention on Thursday increased the risk level for cruise ship travel to its highest level and said it should be avoided, regardless of vaccination status.
The agency bumped up the travel risk level for cruise travel from Level 3 to Level 4, indicating the risk for Covid-19 is “very high.”
The move “reflects increases in cases onboard cruise ships since identification of the Omicron variant,” the CDC website says.
“Since the identification of the Omicron variant, there has been an increase in the number of COVID-19 cases among cruise passengers and crew reported to CDC. Additionally, there has been an increase in the number of cruise ships meeting the COVID-19 case threshold for CDC investigation,” the agency said.
Three ships were listed as orange on December 30, indicating that reported cases are below the CDC’s threshold for investigation. Sixteen ships were listed as green, meaning that the ships had no reported cases of Covid-19.
Green, orange, yellow and red designations indicate a ship’s Covid situation from best to worst. A gray designation is reserved for ships that the CDC has not reviewed for Covid safety.
Decision is ‘perplexing,’ industry association says
Cruise Lines International Association, a trade association, expressed disappointment at the CDC’s elevated risk level.
“The decision by the CDC to raise the travel level for cruise is particularly perplexing considering that cases identified on cruise ships consistently make up a very slim minority of the total population onboard — far fewer than on land — and the majority of those cases are asymptomatic or mild in nature, posing little to no burden on medical resources onboard or onshore,” CLIA said in a statement.
The association said that “cruise ships offer a highly controlled environment with science-backed measures, known testing and vaccination levels far above other venues or modes of transportation and travel, and significantly lower incidence rates than land.”
A statement from the U.S. Travel Association also indicated frustration with the CDC’s advisory.
“The U.S. Travel Association sincerely hopes today’s CDC advisory singling out recreational cruise travel — enacted despite the sector’s robust health practices and high rate (95%) of onboard vaccination — is brief and temporary,” said the statement from Tori Emerson Barnes, the association’s executive vice president of public affairs and policy.
Advice if you decide to cruise anyway
The unvaccinated should also self-quarantine for a five full days after. People on cruise ships should also wear masks in shared places, CDC says.
Most cruise lines are requiring all or the vast majority of passengers and crew to be vaccinated, in compliance with a CDC Conditional Sailing Order that was implemented to allow cruise operations to resume more than a year after the industry came to a standstill at the start of the pandemic.
Many cruise lines also require pre-departure testing, regardless of vaccination status.
Before coronavirus variants brought a rise in breakthrough cases among the vaccinated, some lines did not require vaccinated passengers to wear masks in areas reserved for vaccinated guests.
