Recommendations for Fully Vaccinated People
Cruise Ship Travel During COVID-19
CDC’s Temporary Extension & Modification of Framework for Conditional Sailing Order (CSO) expired on January 15, 2022. CDC recommends that cruise ships operating in U.S. waters choose to participate in CDC’s COVID-19 Program for Cruise Ships.
What You Need to Know
- Make sure you are up to date with your COVID-19 vaccines before cruise ship travel.
- If you are immunocompromised or at increased risk for severe illness from COVID-19, even if you are up to date with your COVID-19 vaccines, talk to your healthcare provider about what additional precautions may be needed before, during, and after travel.
- The virus that causes COVID-19 spreads easily between people in close quarters on board ships. If the virus is spreading on board a cruise ship, passengers and crew are at risk for infection, even if they are up to date with their COVID-19 vaccines.
- Check your cruise ship’s color and vaccination status classification before traveling. Be aware that the ship’s status could change over time and may be different by the time of your cruise.
- Get a COVID-19 viral test as close to time of cruise departure as possible (no more than 3 days) before you travel.
- See more information below about required testing before boarding a ship participating in CDC’s COVID-19 Program for Cruise Ships.
- Get a COVID-19 viral test 3-5 days after your cruise, regardless of your COVID-19 vaccination status.
CDC has listed the cruise ships operating or planning to operate in United States waters. “Gray” designated cruise ships have chosen not to participate in CDC’s COVID-19 Program for Cruise Ships. Check your cruise ship’s status before traveling.
Before You Board
Make sure to plan ahead:
- Check your cruise ship’s color and vaccination status.
- Foreign-flagged  cruise ships operating in U.S. waters and choosing not to participate in CDC’s COVID-19 Program for Cruise Ships (“Gray” status) may have their own COVID-19 health and safety protocols, which CDC has not reviewed or confirmed.
- U.S.-flagged  cruise ships that sail only in U.S. waters and have chosen not to participate in CDC’s Program for Cruise Ships will not be listed on CDC’s Cruise Ship Color Status webpage because they report cases to state and local jurisdictions.
- CDC cannot confirm the COVID-19 public health measures implemented on “Gray” designated ships or cruise ships not listed on CDC’s Cruise Ship Color Status webpage. Therefore, CDC does not have information about precautions and interventions, such as mask use, crew testing, or vaccination status for passengers and crew on these ships.
- Check if your cruise line requires testing and/or vaccination or has any other requirements to board.
- If traveling by air, check if your airline requires any testing, vaccination, or other documents. See below for information about requirements if traveling by air to the United States.
- Get travel insurance. Make sure you have a plan to get care overseas, in case you need it. Consider buying additional insurance that covers health care and emergency evacuation, especially if you will be traveling to remote areas.
- Wearing a well-fitting mask over your nose and mouth is required on planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States and while indoors at U.S. transportation hubs such as airports and train stations. Travelers are not required to wear a mask in outdoor areas of a conveyance (like on open deck areas of a ferry or the uncovered top deck of a bus). Learn more about mask use while on board a cruise ship.
Proof of Vaccination
- Make sure you are up to date with your COVID-19 vaccines.
- Check if your cruise line requires proof of vaccination.
- Non-U.S. citizen, non-U.S. immigrants traveling to the United States by air are required to show proof of being fully vaccinated  against COVID-19. Only limited exceptions apply. Learn more about this requirement.
- If you are up to date with your COVID-19 vaccines, you must get tested with a viral test no more than 3 days before boarding a cruise ship .
- If you are fully vaccinated  for COVID-19, you must get tested with a viral test no more than 2 days before boarding a cruise ship.
- If you are not fully vaccinated for COVID-19, you must get tested with a viral test no more than 3 days before boarding a cruise ship. You will be tested again by the cruise ship personnel on embarkation day before boarding. One of your two tests must be a nucleic acid amplification test (NAAT) such as RT-PCR.
- Check with your cruise line to see if they require a certain type of COVID-19 test.
- If you or your travel companions test positive at embarkation, the cruise ship may deny you from boarding.
- If you are allowed to board after testing positive, you will be required to isolate. Your travel companions who did not test positive will be required to quarantine.
- Check if your cruise line has other testing requirements.
- If traveling to the U.S. by air all passengers ages 2 years and older, regardless of their vaccination status, must show a negative COVID-19 viral test taken no more than 1 day before air travel to the United States, or documentation that they recovered from COVID-19 in the past 90 days, before they board their flight.
- Depending on your travel itinerary, your COVID-19 test result used for air travel may also be used for boarding the cruise ship.
- Children under 2 years of age are not exempt from the preboarding testing requirement for cruise ships participating in CDC’s COVID-19 Program for Cruise Ships.

 Testing requirements only apply to passengers boarding ships that are participating in CDC’s COVID-19 Program for Cruise Ships. Passengers sailing on “Gray” status ships or cruise ships sailing only in U.S. waters (e.g., U.S. rivers) and choosing not to participate in the COVID-19 Program for Cruise Ships are recommended to get tested as soon as possible (no more than 3 days) before their cruise departs. They should also check with their cruise line for testing requirements.
 Fully vaccinated means a person has received their primary series of COVID-19 vaccines. For more information: Stay Up to Date with Your Vaccines | CDC

- Avoid contact with anyone who is sick.
- Avoid touching your eyes, nose, and mouth.
- If you have symptoms of COVID-19, stay in your cabin and notify the onboard medical center immediately. It’s important to report your symptoms, even if they are mild, to protect others on board including passengers at increased risk for severe illness and crew.
What to expect if you develop COVID-19 symptoms or are confirmed to have COVID-19 while on board:
- You will be isolated immediately.
- The cruise ship will follow its routine protocol for managing people with suspected or confirmed COVID-19 on board. The isolation may occur on board or at a shoreside location.
- If your ship allows a shortened isolation option for passengers on board then you will have to follow additional public health measures, including dining inside your cabin and properly wearing a well-fitting mask at all times when you are outside your cabin, until 10 days after your symptoms started or your positive test was taken if you did not have symptoms.

- If you are up to date with your COVID-19 vaccines, at the cruise ship operator’s discretion, you will be required to:
- Quarantine for 5 days after last exposure; or
- Be tested daily for COVID-19 for 5 days after your last exposure instead of a 5-day quarantine.
- Regardless of your vaccination status, during the 10 days after your last exposure, you will need to follow additional public health measures including dining inside your cabin and properly wearing a well-fitting mask at all times when you are outside your cabin (indoors and outdoors).
- If you are not up to date with your COVID-19 vaccines, at the cruise ship operator’s discretion, you will be required to:
- Cruise ship operators may have their own requirements. If you have questions about a cruise line’s specific policies, please contact them directly.

After You Disembark
- Get tested 3–5 days after your trip.
- If your test is positive, isolate yourself to protect others from getting infected. Learn what to do if you are sick and when it is safe to be around others.
- Check for COVID-19 testing locations near youexternal icon.
- You may be contacted after disembarking if you were exposed to someone confirmed with COVID-19 while on board the cruise ship.
Protect Yourself and Others
- Self-monitor for COVID-19 symptoms for 10 days after travel; isolate and get tested if you develop symptoms, regardless of your vaccination status.
- Always follow state, localexternal icon, and territorial recommendations or requirements related to travel.
If you are not up to date with your COVID-19 vaccines:
- Stay home and self-quarantine for a full 5 days after cruise travel, even if you do not have symptoms.
If You Recently Recovered from COVID-19*
- Do not board a cruise ship if you developed COVID-19 less than 10 days ago (day 0 is the day your symptoms started or the day your positive test sample was taken if you had no symptoms).
- If you tested positive for COVID-19 infection no less than 10 days and no more than 90 days before the date of embarkation and recovered (regardless of your vaccination status), you do NOT need to get tested before or after cruise travel unless you have symptoms. People can continue to test positive for up to 90 days after diagnosis and not be infectious to others.
- Travel with a copy of your positive test result and a letter from your healthcare or a public health official that states you have been cleared for travel. The positive test result and letter together are referred to as “documentation of recovery.” If you are asked by officials in a foreign country, you may be required to show this documentation.
- You also do NOT need to self-quarantine after cruise travel if you have recently (within the past 90 days) recovered from COVID-19.
- If you develop COVID-19 symptoms after travel, isolate and consult with a healthcare provider for testing recommendations.
*People are considered recovered from COVID-19 after 10 full days after their symptoms started and if they are fever-free for 24 hours (without the use of fever-reducing medication) and their other symptoms have improved (the day symptoms started is day 0), or 10 days after their positive test sample was collected if they didn’t have symptoms (the day of the positive test is day 0).
