Norovirus Outbreak on Caribbean Princess Affects 115 Passengers

A gastrointestinal outbreak has affected 115 people aboard the Caribbean Princess cruise ship after the vessel departed from Florida. As of May 10, 2026, reports indicate that the individuals have presented symptoms associated with norovirus.

The norovirus outbreak involves passengers and crew members who have experienced gastrointestinal distress. The ship, which began its itinerary in Florida, is monitoring the health of those on board to contain the spread of the virus.

Norovirus is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines. Common symptoms include nausea, vomiting, diarrhea, and stomach pain. Because the virus can survive on surfaces and is resistant to many common disinfectants, it frequently spreads in crowded environments such as cruise ships.

Cruise Ship Health Protocols

In instances of gastrointestinal illness, cruise lines typically implement enhanced sanitation measures. These protocols generally include the increased use of disinfectants on high-touch surfaces and the isolation of symptomatic passengers in their cabins to prevent further transmission.

Cruise operators are required to report outbreaks of gastrointestinal illness to health authorities. These reports help regulators track the prevalence of the virus and ensure that the vessel is following established hygiene and safety guidelines to protect the remaining passengers and crew.

The Caribbean Princess is managing the 115 identified cases as the voyage continues. Further updates regarding the health status of the passengers or changes to the ship’s itinerary have not been confirmed.
