Wash hands frequently, avoid touching your face, and stay away from shared surfaces to help prevent the spread of norovirus on cruise ships.
A norovirus outbreak has swept through the Caribbean Princess cruise ship mid-voyage, leaving more than 100 passengers and crew members ill and triggering a full federal investigation — the second such incident involving a Princess Cruises vessel in just two months. ()
Despite the outbreak, passengers on board report that life at sea has continued with surprising normality, even as the ship’s crew moved swiftly to contain the spread.
The Caribbean Princess departed on April 28, 2026, on a 13-night voyage from Barbados to Port Canaveral. During the voyage, the norovirus outbreak met the CDC’s Vessel Sanitation Program threshold for public posting because more than 3% of passengers reported gastrointestinal illness.
The ship made stops in the Bahamas, Puerto Rico, Aruba, St. Maarten, Curacao, and Bonaire before the norovirus outbreak was confirmed. The outbreak sickened 102 of the ship’s 3,116 passengers and 13 crew members, according to the CDC.
The predominant symptoms were vomiting and diarrhea. The outbreak was formally reported to the CDC on Thursday, 7 May 2026, triggering a public notification and investigation process.
What Is Norovirus, and Why Do Cruise Ships Keep Getting Hit?
Norovirus is a highly contagious virus that commonly causes vomiting and diarrhea and can spread quickly in close quarters. Healthcare facilities such as nursing homes and hospitals experience the most reported outbreaks — over half of US norovirus outbreaks occur in long-term care facilities. Cruise ships face a similar vulnerability: they combine high passenger density, communal dining, and rapid turnover in a confined maritime environment.
The CDC’s Vessel Sanitation Program monitors outbreaks across the cruise industry with specific reporting thresholds. Cruise lines are required to report outbreaks to the agency when at least 3% of passengers or crew report gastrointestinal symptoms. The Caribbean Princess met that threshold, which triggered the public posting and field investigation.
Passengers Praise Caribbean Princess Crew’s Swift Response Amid Norovirus Outbreak
Despite the outbreak, passengers described conditions on the ship as far from chaotic. Jan van Milligen, who had spent 21 days on board with relatives and friends from South Africa, told reporters: “The normal atmosphere is still here. We went to a show last night, had dinner and breakfast this morning.”
Van Milligen took notice of the stricter sanitation measures aboard. “The cruise line made all precautions to stop the spread,” he said, adding that “they were very professional” and passengers were informed about the situation in a timely way.
Among the changes he noticed were passengers becoming more cautious about hygiene, including washing their hands more frequently. Passengers were also no longer allowed to serve themselves at the buffet.
Another passenger, Donna Leonte, who boarded with her husband and friends to celebrate her wedding anniversary, echoed the sentiment. “People need to be mindful and take precautions. We are not missing any activities,” she said. “The buffet is well-staffed and they are handing out dishes, utensils and food. They’re doing an excellent job.”
Leonte said ship staff kept guests informed throughout. “They’ve said it’s been sanitized, that they’ve been cleaning everything. They let us know if there’s any more people that have contracted it,” she said.
The response on board was swift and multi-layered. Princess Cruises and the crew increased cleaning and disinfection procedures according to their outbreak prevention and response plan, collected stool specimens from gastrointestinal illness cases for testing, and isolated ill passengers and crew members.
CDC Launches Investigation as Princess Cruises Steps Up Sanitization After Norovirus Outbreak
The CDC’s Vessel Sanitation Program launched a field response for an environmental assessment and outbreak investigation to assist the ship in controlling the spread.
Princess Cruises issued a statement confirming the situation while seeking to manage its scale. The company said it could “confirm that a limited number of individuals reported mild gastrointestinal illness during the April 28 Caribbean Princess voyage from Port Everglades. We quickly disinfected every area of the ship and added extra sanitizing throughout the voyage.”
The company added that upon arrival at Port Canaveral on May 11, the Caribbean Princess would undergo comprehensive cleaning and disinfection before departing for her next voyage. Infected passengers were asked to stay in their rooms and quarantine, and were being checked on by medical staff every day.
This is not an isolated incident for Princess Cruises, nor for the broader cruise industry. The outbreak on the Caribbean Princess comes just over a month after another norovirus outbreak was reported on the Star Princess. In March, that ship faced an outbreak that sickened more than 104 guests and 49 crew members on a voyage departing Fort Lauderdale with stops in Honduras, Belize, and the Mexican Riviera.
The Star Princess voyage ran from March 7 to March 14, 2026. By March 11, the ship had reported to the CDC that 141 of 4,307 passengers and 52 of 1,561 crew had reported gastrointestinal illness — 3.3% of passengers and 3.3% of crew. The predominant symptoms were diarrhea and vomiting, and norovirus was confirmed as the cause.
In early January, the CDC also reported that an outbreak on board a Holland America cruise ship had sickened more than 80 people after departing from Fort Lauderdale at the end of December 2025.
The pace of four outbreaks through the first five months of 2026 is notably lower than the same period in 2025, when the CDC had reported more than a dozen outbreaks by May and the full year total reached 23. Of those 2025 outbreaks, 18 were caused by norovirus.
On arrival at Port Canaveral on May 11, the Caribbean Princess will undergo comprehensive cleaning and disinfection before her next voyage, with the CDC conducting an environmental assessment as part of its ongoing investigation. The response measures taken on board — isolating ill passengers, increasing disinfection, and consulting with the CDC — reflect years of cruise industry protocol refinement following previous high-profile norovirus outbreaks.
The norovirus outbreak aboard the Caribbean Princess is a reminder that even the most tightly managed cruise environments remain vulnerable to highly contagious viruses.
With 115 passengers and crew affected across a 13-day voyage, and the ship’s arrival at Port Canaveral imminent, authorities and the cruise line are focused on containment and deep cleaning before the next sailing departs.
For the wider cruise industry, the pattern of repeated outbreaks across multiple Princess vessels in early 2026 will likely prompt fresh scrutiny of sanitation protocols — even as the overall outbreak rate remains below last year’s levels.
