The U.S. Centers for Disease Control and Prevention is advising Americans to avoid cruise travel, regardless of their vaccination status for COVID-19.

The latest guidance from the CDC says,

"Even fully vaccinated travelers may be at risk for getting and spreading COVID-19 variants. The virus that causes COVID-19 spreads easily between people in close quarters on board ships, and the chance of getting COVID-19 on cruise ships is very high, even if you are fully vaccinated and have received a COVID-19 vaccine booster dose," the guidance says.

The guidance comes during the latest surge of the omicron coronavirus variant and after outbreaks on several cruise ships.

If traveling on a cruise ship, the CDC says passengers should be fully vaccinated before travel and get a booster dose if eligible. Testing one to three days before a cruise and three to five days after returning from a trip are also recommended, regardless of vaccination status or symptoms.

The latest guidance also suggests self-quarantine for full days after cruise travel for cruise passengers who are not fully vaccinated.

Anyone traveling on a cruise should wear a mask, maintain social distancing of 6 feet from other travelers indoors and outdoors, wash hands or use sanitizer often, avoid contact with anyone who is sick and avoid touching eyes, nose, and mouth. Anyone with COVID-19 symptoms should stay in their cabins and notify the onboard medical center immediately.
