Another norovirus outbreak has struck a major cruise vessel, highlighting the persistent vulnerability of crowded ships to highly contagious gastrointestinal illnesses.
The Caribbean Princess departed Port Everglades in Fort Lauderdale, Florida, on April 28 for a 13-night Southern Caribbean itinerary carrying more than 3,100 passengers and over 1,100 crew members. According to the Centers for Disease Control and Prevention (CDC), 102 passengers and 13 crew reported symptoms consistent with norovirus infection. Laboratory tests confirmed the presence of the virus.
Passengers began experiencing classic symptoms including vomiting, diarrhea, abdominal cramps, and nausea shortly after departure. The ship continued its voyage with planned stops in tropical ports and is scheduled to return to Port Canaveral, Florida, on May 11.
Princess Cruises described the affected individuals as a “limited number” experiencing mild symptoms. The company stated it responded swiftly by disinfecting all areas of the ship and implementing additional sanitizing measures throughout the voyage, with plans for a comprehensive cleaning upon return to port.

Norovirus Explained
As noted by the Mayo Clinic, norovirus ranks among the leading causes of stomach-related illness globally. It spreads rapidly in confined environments such as cruise ships, schools, and long-term care facilities through contaminated food, water, surfaces, or direct person-to-person contact. Symptoms typically appear suddenly and resolve within a few days for most healthy individuals, though the virus can pose greater risks of dehydration for older adults, children, and those with weakened immune systems.
Cruise ships present ideal conditions for transmission due to shared dining areas, entertainment venues, and public spaces. Once introduced, the hardy virus proves difficult to eradicate completely despite enhanced cleaning protocols introduced industry-wide since the COVID-19 pandemic.
This marks the second reported norovirus incident on a Princess Cruises vessel this year. In March, the Star Princess experienced over 150 cases following a departure from Fort Lauderdale. The CDC’s Vessel Sanitation Program continues to monitor outbreaks on vessels operating from U.S. ports, including through stool sample testing, isolation of symptomatic individuals, and intensified sanitation efforts.
Passengers have observed increased hand sanitizer stations and frequent cleaning of high-touch areas. Some chose to remain in cabins as a precaution after learning of the illnesses. No deaths or severe complications have been reported in the current outbreak.
Health authorities continue to emphasize basic preventive steps: thorough hand washing, avoiding shared utensils, and promptly reporting symptoms to crew. The Caribbean Princess will undergo further deep cleaning after disembarkation while the CDC maintains oversight.
