pages]. PurposeCruise ships are densely populated congregate settings where respiratory viruses, including SARS-CoV-2 (the virus that causes COVID-19), can spread easily among travelers (passengers and crew) on board. This document is intended to assist cruise ship operators in establishing health and safety protections to reduce the risk of introduction and spread COVID-19 during passenger operations and preserve onboard medical capacity. Cruise ship operators should carefully consider and incorporate these recommendations in developing their own health and safety protocols. Plans should include triggers for a graduated approach to outbreak management in response to increasing case counts or other public health concerns. This guidance is based on the best available science regarding the subject areas covered. CDC will reevaluate the guidance for cruise ships periodically, based on scientific evidence and the state of the pandemic, and update the guidance as needed. CDC will notify cruise ship operators if the guidance is updated. Onboard COVID-19 Response PlansCruise ships should develop and maintain COVID-19 response plans to prevent and mitigate introduction and onboard transmission of COVID-19. These plans should incorporate:
[1] Confirmed COVID-19 means laboratory confirmation for SARS-CoV-2, the virus that causes COVID-19, by viral test. [2] COVID-19-like illness clinical criteria include the following:
Shoreside Response PlansCruise ships should develop and maintain shoreside response plans to prevent and mitigate the introduction of COVID-19 to port communities. When developing their response plans, cruise ship operators should coordinate with the U.S. port authorities where the cruise ship operator intends to conduct passenger voyages and all health departments exercising jurisdiction over those ports.
Shoreside response plans should include the following components: Port Operation Components(Relating to maintaining the health and safety of travelers and port personnel)
Medical Care Components(Relating to medical care, medical evacuation, and medical transport for travelers in need of care)
Housing Components(Relating to housing plans for isolation or quarantine—as needed—of persons with suspected or confirmed COVID-19 and close contacts after disembarkation)
COVID-19 VaccinesCDC recommends all eligible travelers be up to date with their COVID-19 vaccines. In addition to the protection COVID-19 vaccines provide to individual travelers in preventing severe illness or death from COVID-19, having a high proportion of travelers on board who are up to date with COVID-19 vaccines reduces the likelihood that cruise ships’ medical centers are overwhelmed by cases of COVID-19. Surveillance for COVID-19
To reduce the spread of SARS-CoV-2, cruise ship operators should:

[4] Back-to-back sailing refers to passengers who stay on board for two or more voyages. Procedures for Symptomatic Travelers (Crew and Passengers) and Close ContactsOnboard COVID-19 Testing and Quarantine of Close ContactsSymptomatic Travelers: Identifying and isolating travelers with possible symptoms of COVID-19 as soon as possible is essential to minimize transmission of the virus. All travelers onboard the cruise ship with signs and symptoms of COVID-19, regardless of vaccination status, should be isolated and tested for SARS-CoV-2 infection immediately upon notifying medical staff of symptom onset. Results should be reported to CDC in aggregate through the EDC form. Close Contacts: Because of the potential for asymptomatic and pre-symptomatic transmission in this high-risk residential congregate setting, it is important that close contacts of individuals with SARS-CoV-2 infection be quickly identified and tested. CDC has provided guidance for quarantine in community and high-risk congregate settings. In addition to this guidance, cruise ship operators can consider the following options.
Onboard COVID-19 Testing for Symptomatic Travelers (Crew and Passengers) and Testing and Quarantine of Close Contacts† Onboard COVID-19 Testing for Symptomatic Travelers (Crew and Passengers) and Testing and Quarantine of Close Contacts
† If a cruise ship cannot maintain minimum safe manning because crew members are in isolation or quarantine, the cruise ship may consider a “working quarantine” (i.e., crew perform job duties then return to cabin quarantine) for essential crew who are not up to date with their COVID-19 vaccines to ensure the safety of ship as it immediately returns to port. When choosing essential crew for a working quarantine, the cruise ship should prioritize crew who are fully vaccinated over those who are not. See guidance below regarding masking and dining. ^ Individual should properly wear a well-fitting mask at all times when outside of cabin (indoors and outdoors) until 10 days after the last close contact with someone with COVID-19 (the date of last close contact is considered day 0). They should also wear a well-fitting mask inside their cabin if any other person (e.g., a crew member) enters the cabin.
Considerations for Isolation or QuarantineCruise ship operators should consider the following elements when isolating cases or quarantining close contacts:
Discontinuation of Isolation for Travelers (Crew and Passengers)To calculate the traveler’s isolation period, day 0 is their first day of symptoms or the day of their positive viral test if asymptomatic. CDC has provided guidance for isolation in community and high-risk congregate settings. If isolation is ended before 10 days are completed, travelers should properly wear a well-fitting mask when outside of cabin (indoors and outdoors) through day 10. During this time, these individuals should have in-cabin dining and also wear a well-fitting mask inside their cabin if any other person (such as a crew member) enters the cabin. Cruise ship operators can consider the following for the discontinuation of isolation:
[6] As noted in the labeling for authorized over-the-counter antigen tests: Negative results should be treated as presumptive. Negative results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Onboard Medical CentersMedical centers on cruise ships can vary widely depending on ship size, itinerary, length of cruise, and passenger demographics.
LaboratoryTo ensure safe and effective laboratory procedures, cruise ship operators should:
Disembarking Travelers (Crew and Passengers)If a traveler is known to be infected with or has symptoms compatible with COVID-19:
Disembarkation to Obtain Medical CareCruise ship operators should have clear protocols that avoid medical evacuations at sea to the extent possible for COVID-19 and other medical conditions. Protocols should rely on commercial resources (e.g., ship tender, chartered standby vessel, chartered airlift) for unavoidable medical evacuations at sea and be designed to minimize the burden on federal (including U.S. Coast Guard), state, and local government resources. Travelers with COVID-19 should properly wear a well-fitting mask covering their mouth and nose during the disembarkation process and throughout transportation to the shoreside healthcare facility, if a mask can be tolerated and does not interfere with medical treatment (e.g., supplemental oxygen administered via an oxygen mask).

COVID-19 Screening Testing of CrewScreening Testing of Newly Embarking Crew
Routine COVID-19 Screening Testing and Monitoring of All CrewScreening testing is defined as testing of asymptomatic crew who have not been identified as a close contact to a confirmed case or a case of COVID-19-like illness.
Crew Screening Testing Specifications
Preventive MeasuresStrict adherence to passenger and crew testing protocols and vaccination levels will aid in mitigating transmission and illness onboard; however, continued prevention efforts are necessary to reduce the possibility of transmission to others if a case occurs on board the ship.

7-day Crew or Passenger Attack Rates Crew: 7-day crew attack rates are calculated using the cumulative number of crew cases in the last 7 days divided by the average number of crew onboard the ship in the last 7 days. Passenger: 7-day passenger attack rates are calculated using the cumulative number of passenger cases in the last 7 days divided by the average number of passengers onboard the ship in the last 7 days. The following persons should not be included in these calculations because they do not pose a risk of transmission onboard the ship:
Disclaimer: The accuracy of attack rates is dependent upon the frequency of routine screening testing of asymptomatic travelers on board. Enhanced Preventive Measures (recommended when 7-day crew or passenger attack rate reaches 1%)
Outbreak Public Health Interventions (recommended when 7-day crew or passenger attack rate reaches 2%)
Considerations for Suspending OperationsAdditional public health precautions, such as returning to port immediately or delaying the next voyage, should be taken to help ensure the health and safety of onboard travelers or newly arriving travelers. A ship should consider suspending operations based on the following factors:
[7] These thresholds are subject to change based on the characteristics of the dominant COVID-19 variant in the U.S. Infection Prevention and Control PlanInfection prevention and control (IPC) is critical to reducing the spread of SARS-CoV-2. Each cruise ship should maintain a written Infection Prevention and Control Plan (IPCP) that details standard procedures and policies to specifically address infection control and cleaning/disinfection procedures to reduce the spread of COVID-19. To reduce the spread of SARS-CoV-2, cruise ship operators should include the following as part of a written IPCP:
Cleaning and DisinfectionCurrent evidence suggests that COVID-19 may remain viable for hours to days on surfaces made from a variety of materials. Cleaning of visibly dirty surfaces followed by disinfection is a best practice measure for prevention of COVID-19 transmission. In addition to routine cleaning and disinfection strategies, ships should focus on cleaning and disinfecting common areas where crew members may come into contact with infectious persons. Frequent, routine cleaning and disinfection of commonly touched surfaces such as handrails, countertops, and doorknobs with an EPA-registered disinfectant effective against coronaviruses is strongly recommended. Additional information on cleaning and disinfecting on cruise ships can be found on CDC’s Interim Guidance for Ships on Managing Suspected Coronavirus Disease 2019 and CDC’s Vessel Sanitation Program 2018 Operations Manual [PDF – 291 pages]. Medical personnel who have direct contact with isolated or quarantined persons and crew members who handle waste or soiled linens should wear proper PPE per CDC’s Interim Guidance for Ships on Managing Suspected Coronavirus Disease 2019. Other environmental considerations include:
Frequently Asked QuestionsThe following frequently asked questions (FAQs) for cruise ship operators and medical center personnel to provide more detail about CDC recommendations for cruise ships. CDC recommends all eligible travelers be up to date with their COVID-19 vaccines. A threshold cruise ship operators can consider is operating with least 90% passengers and 95% crew who are up to date with their COVID-19 vaccines. While the protection COVID-19 vaccines provide to individual travelers in preventing severe illness or death from COVID-19, having a high proportion of travelers on board who are up to date with COVID-19 vaccines reduces the likelihood that cruise ships’ medical centers are overwhelmed by cases of COVID-19. Yes, for the purpose of the cruise ship guidance, if an eligible traveler has not received a booster dose but is within 1 month of their recommended booster vaccination date, then they can be considered up to date with their COVID-19 vaccines. Example for mRNA vaccines (Pfizer BioNTech/Moderna):
Example for J&J/Janssen vaccine:
How many days after travel should I quarantine?Quarantine1 for at least 5 days after last exposure. Quarantine can end after Day 5 if symptoms are not present and a test collected on Day 5 or later tests negative. If unable to test or choosing not to test, and symptoms are not present, quarantine can end after Day 10.
How long do international travelers have to quarantine?You are at risk of testing positive to COVID-19 for up to 14 days after being exposed to someone with the virus. Most people will test positive in the first 7 days. This is why it is important to be careful to protect the people around you, especially those who are at higher risk of severe illness, during this time.
What precautions should I take after traveling internationally during the CovidStay home for five days after travel. If at any point you test positive for the virus that causes COVID-19 , stay home. Stay at home and away from others if you develop symptoms. Follow public health recommendations.
