Health & Safety
CLIA cruise lines go to great lengths to support the health and safety of all onboard. From cleaning practices to passenger screening and robust oversight over onboard health and safety practices, the cruise industry is one of the most vigilant industries as it relates to safety, sanitation and public health protocols.
Equipped for Health
CLIA members are prepared and proactive when it comes to the health and wellness of passengers and crew.

Ensuring Health at Sea
The cruise industry is a model for health protocols and practices that make cruising one of the safest forms of travel.
Crewmembers regularly clean and sanitize the ship’s facilities, including:
- Cabins cleaned at least once daily;
- Restaurants and snack areas cleaned regularly; and
- Common areas such as pools and elevators cleaned throughout the day.
At the end of every cruise, crewmembers clean the ship from top to bottom using designated cleaning supplies and sanitation procedures.
Pre-boarding health screenings help identify ill passengers or crewmembers prior to boarding. The most common health screening protocol is a health questionnaire. Passengers indicate if they or their traveling companions have had any recent symptoms of illness. Passengers and crewmembers who may be ill are assessed by medical staff before they interact with other guests.
Cruise Lines International Association (CLIA) Cruise Line Members collaborated with the American College of Emergency Physicians (ACEP) to develop and implement guidelines on cruise ship medical facilities. These guidelines, which are mandatory for CLIA oceangoing Cruise Line Members, specify that cruise ships must have at least one qualified medical professional available 24/7 for medical bay visits or cabin “house calls.” Also, cruise ships must have an examination room, an intensive care room and equipment for processing labs, monitoring vital signs and administering medications. Patients requiring more comprehensive facilities or treatment are typically referred to a shore side medical facility.
Passenger and crewmember health is protected by a robust system of oversight and enforcement. Public health authorities worldwide inspect cruise ships and enforce health requirements. Cruise ships calling on U.S. ports, for example, receive at least two unannounced health inspections every year. In addition, cruise ships undergo three or more formal internal public health inspections each year.
Onboard staff must be trained in first aid and public health practices. No matter their job onboard, crew must be trained in safety and first aid procedures, such as emergency procedures, signals and alarms; evacuation procedures; and fire prevention and fire safety.
CDC’s Vessel Sanitization Program
The cruise industry voluntarily participates in the Center of Disease Control and Prevention’s (CDC) Vessel Sanitization Program (VSP), which provides a level of federal scrutiny that is unprecedented within the travel and hospitality industry. There is no similar federal program for hotels, airlines or restaurants.
The VSP conducts operational sanitation inspections twice a year. As part of these unannounced inspections, the VSP looks at eight core areas of cruise ships:
- Medical facilities
- Potable water systems
- Swimming pools and whirlpool spas
- Galleys and dining rooms
- Child activity centers
- Hotel accommodations
- Ventilation systems
- Common areas of the ship
The VSP scores for cruise ships reflect the effectiveness of the cruise line protocols. Only 1% of ships since 1990 (the current history of stores published on the CDC site) have been below 86 points, and the average rating of ships is 95.76 points over that same time period. In the past 24 months, the average is 95.95.
Cruise ships are the only travel sector that routinely report illnesses to the CDC and where you can find a central list of ships and their scores. By contrast, you won’t find a listing of all restaurants or hotels or airplanes like you find for cruise ships. There is simply more visibility and reporting to health authorities from cruise, which should not be confused to mean a higher incidence rate on a cruise ship compared to other places.
Occurrences of gastrointestinal illness (GI) illnesses are rare on cruise ships (1 in 5,500 chance) compared to other settings (1 in 15 on land). According to information on the CDC website, the most common settings for GI are healthcare facilities, followed by restaurants or catered events, schools, daycares. By comparison, spread in cruise ship settings is far less common (only 1% of all cases), but CDC requires it be reported.

Safety
Cruise ships are one of the safest vacation options in the world as a result of comprehensive protocols and multiple layers of security.
Advanced Security Teams
Major cruise lines have sophisticated security departments run by former federal, state and military law enforcement officials and trained ship security personnel are on call 24/7

Strict Safety Oversight
Cruise ships are among the most scrutinized vessels at sea. Beginning at design and constructions, the International Maritime Organization (IMO), flag and port state authorities, and classification societies provide strict safety standards and oversight throughout a ship’s operations.
