TL;DR
More than 150 people on Princess Cruises’ Star Princess became sick with norovirus-like illness during an eight-day Caribbean cruise, according to U.S. health authorities.
Why This Matters
Norovirus is one of the most common causes of gastrointestinal illness worldwide. It spreads easily in close quarters, which makes cruise ships, nursing homes, schools, and other group settings especially vulnerable. While most healthy adults recover within a few days, the virus can be more serious for young children, older adults, and people with underlying health conditions.
The Centers for Disease Control and Prevention (CDC) tracks outbreaks on cruise ships that sail from U.S. ports through its Vessel Sanitation Program. Each incident adds to a growing data set that shapes sanitation standards, inspections, and public health guidance for the entire industry. For frequent cruisers, especially retirees, these updates provide an early picture of how reliably different lines detect, report, and respond to illness on board.
Norovirus outbreaks also have economic implications. Cruise lines must devote staff and resources to deep cleaning, may face reputational damage, and sometimes adjust itineraries. For ports that depend on cruise tourism, recurring health incidents can affect local businesses and public health planning as they prepare for thousands of visitors arriving in a single day.
Key Facts & Quotes
According to the CDC, 104 passengers and 49 crew members aboard the Star Princess reported gastrointestinal symptoms, including diarrhea and vomiting, during a Caribbean voyage in March. The ship was carrying 4,307 guests and 1,561 crew members, and the cruise line notified federal health officials on March 11 after the vessel had already spent several days at sea.

The Star Princess departed Fort Lauderdale, Florida, on March 7 for an eight-day itinerary, data from the CDC summary and cruise-tracking site CruiseMapper show. The ship visited ports in Honduras, Belize, and the Mexican Riviera before returning to Fort Lauderdale. When the outbreak was first reported, the vessel was sailing between Belize City and Cozumel, according to the itinerary.
Princess Cruises told the CDC it activated its outbreak response plan, which includes stepped-up cleaning and disinfection, isolating sick passengers and crew, and collecting stool samples for testing. The CDC said its Vessel Sanitation Program “is doing a field response to conduct an environmental assessment and outbreak investigation,” aiming to identify how the virus spread and what measures might reduce future risk.
Norovirus and similar illnesses have affected multiple ships in recent months. In early January, a Holland America vessel reported more than 80 sickened passengers and crew after leaving Fort Lauderdale, according to CDC records. In February, an outbreak of an undetermined gastrointestinal illness on the luxury Regent Seven Seas line sickened 27 people on a Miami-to-Honolulu trip.
What It Means for You
For travelers, the latest update is a reminder that cruise vacations, while popular and often affordable, carry some infectious disease risk. The CDC estimates that norovirus causes tens of millions of illnesses in the United States each year, not just on ships but also in homes, restaurants, and hospitals.
Before booking a cruise, you can review recent ship inspection scores and outbreak reports on the CDC’s public website to get a sense of a line’s health track record. On board, regular handwashing with soap and water, especially before eating and after using the restroom, remains one of the most effective ways to reduce the risk of norovirus. If you have chronic health issues, it may be worth discussing cruise travel with your doctor and considering travel insurance that covers trip interruption due to illness.
