Key Takeaway:
- Norovirus outbreak sickened 115 people aboard Caribbean Princess during an 11-day Caribbean voyage.
- CDC launched an onboard investigation after the ship arrived at Port Canaveral.
- The cruise line increased sanitation, isolation, and monitoring measures to contain the spread.
A Princess Cruises ship carrying more than 100 passengers and crew sickened by norovirus arrived Monday at Port Canaveral after completing an 11-day Caribbean voyage, prompting a federal outbreak investigation and intensified sanitation measures.
Cruise Ship Arrives After Norovirus Outbreak At Sea
The Caribbean Princess docked Monday morning after an onboard norovirus outbreak affected passengers and crew during a sailing that departed April 28 from Port Everglades in Fort Lauderdale, federal health officials said.
According to the Centers for Disease Control and Prevention, 102 of the ship’s 3,116 passengers, or 3.3%, reported illness linked to the highly contagious virus. Thirteen of the vessel’s 1,131 crew members, or 1.2%, also became sick.
The outbreak was first reported on May 7 through the agency’s Vessel Sanitation Program, which monitors gastrointestinal illness on cruise ships calling at U.S. ports.
Norovirus commonly causes diarrhea and vomiting and spreads quickly in close environments such as cruise ships, hospitals, and schools.
Cruise Line Implements Cleaning And Isolation Measures
Princess Cruises said it increased sanitation procedures after identifying the outbreak. The company isolated sick passengers and crew, intensified cleaning and disinfection efforts, and collected stool samples for laboratory testing.
Company officials also consulted with federal health authorities ahead of the ship’s arrival to review reporting requirements and sanitation practices.
A CDC response team boarded the vessel upon arrival to conduct an environmental assessment and outbreak investigation aimed at limiting further transmission.
“The health and safety of guests and crew remain our highest priority,” Princess Cruises said in a statement, adding that enhanced cleaning protocols were implemented throughout the voyage.
CDC officials said cruise operators are required to report suspected outbreaks before arriving at U.S. ports, allowing federal teams to prepare response measures.
Outbreak Marks Fourth Cruise Illness Event This Year
The incident represents the fourth cruise ship outbreak tracked by the CDC in 2026. Earlier cases included two E. coli outbreaks aboard the Oceania Insignia and the Regent Seven Seas Mariner, as well as another norovirus outbreak on Princess Cruises’ Star Princess.
Federal officials noted that cruise ships operate under stricter reporting rules than many land-based hospitality businesses. Hotels and resorts, for example, are not federally required to report similar illness clusters.
Health experts emphasize that norovirus outbreaks are common worldwide and often originate from contaminated food, surfaces, or person-to-person contact. The virus can spread rapidly, but usually resolves within several days for most healthy individuals.
Despite the outbreak, the Caribbean Princess is scheduled to continue operations, beginning a series of Caribbean and Bahamas sailings expected to run through October before the vessel returns to Port Everglades.
Passengers scheduled for upcoming voyages were notified of enhanced sanitation practices and monitoring procedures, the cruise line said.
Federal investigators will continue reviewing onboard conditions and testing results to determine the outbreak’s source and recommend additional prevention measures.
