Passengers aboard Star Princess, one of Princess Cruises’ newest ships, recently experienced an unexpected disruption after a gastrointestinal illness spread among guests and crew during a Caribbean sailing.
The outbreak, believed to be caused by norovirus, affected more than 150 people onboard.
Although the situation was quickly addressed with strict health protocols, it marked the first major illness outbreak since the ship entered service in late 2025.
While outbreaks like this can sound alarming, cruise lines have well-established procedures to manage them and protect passengers on current and future voyages.
Illness Reported During March Caribbean Sailings
The outbreak occurred during voyages that departed Fort Lauderdale, Florida, on March 7, 2026.
Star Princess was operating two itineraries at the same time:
- A 7-night Western Caribbean sailing.
- A 14-night extended Caribbean cruise.
Both voyages were scheduled to conclude on March 14.
During the cruise, a number of passengers and crew began experiencing gastrointestinal symptoms commonly linked to norovirus.
Reported symptoms included:
- Vomiting
- Diarrhea
- Nausea
- Abdominal cramps
According to health monitoring data, 104 passengers and 49 crew members reported symptoms during the sailing.
When an Illness Becomes an “Official Outbreak”
Health authorities monitor cruise ships closely for signs of contagious illness.
An outbreak is typically reported when more than 2% of passengers or crew develop gastrointestinal symptoms during a voyage.
On Star Princess:
- Around 2.4% of passengers reported symptoms.
- About 3.1% of crew members were affected.
Because those numbers crossed the monitoring threshold, the situation was classified as a gastrointestinal outbreak.
Despite the numbers, the vast majority of passengers onboard remained healthy throughout the cruise.
Crew Immediately Activated Enhanced Sanitation Protocols
Once the illness was identified, crew members began following strict health guidelines designed to contain the virus and prevent further spread.
Cruise ships have detailed response plans for these situations, and Star Princess quickly implemented additional sanitation procedures across the vessel.
Measures included:
- Isolating passengers who showed symptoms.
- Increasing cleaning throughout the ship.
- Disinfecting high-touch surfaces more frequently.
- Monitoring guests for additional symptoms.
The ship’s medical team also collected samples to confirm the virus responsible for the illness.
Passengers Notice Increased Cleaning Across the Ship
Guests currently onboard reported seeing crew members working constantly to keep the ship sanitized.
According to passenger comments shared online, cleaning crews focused heavily on high-traffic areas around the ship.
Passengers said they observed crew members:
- Frequently disinfecting stair railings.
- Cleaning public seating areas.
- Wiping down restaurant tables after every use.
- Removing shared items like salt and pepper shakers.
Many passengers also reported that cabin stewards were spending additional time thoroughly cleaning staterooms.
Some guests even mentioned that bed linens were replaced across the ship as an extra precaution.
Handwashing and Hygiene Encouraged Across the Ship
To help reduce further spread of the virus, crew members also increased efforts to encourage proper hygiene among passengers.
Several additional measures were introduced throughout the ship.
These included:
- Crew stationed at restaurant entrances, reminding guests to wash their hands.
- Additional hand sanitizer stations around the ship.
- Frequent announcements provide health updates.
Passengers were also advised to contact the ship’s medical team immediately if they began experiencing symptoms.
Boarding for the Next Cruise Will Be Slightly Delayed
Because the current voyage ends on March 14, Princess Cruises decided to delay the next embarkation in Fort Lauderdale.
The extra time will allow the crew to complete a full deep cleaning of the ship and terminal before welcoming new passengers.
Future guests scheduled to board the next sailing were notified about the delay through email communication.
While waiting longer to board may feel inconvenient, the extra sanitation time helps ensure the ship is fully prepared for its next voyage.
Deep Cleaning Is Standard Practice After Illness Reports
Cruise ships occasionally delay boarding after illness incidents so crews can perform extensive sanitation work without passengers onboard.
This process often includes:
- Deep cleaning cabins and bathrooms.
- Sanitizing dining venues and kitchens.
- Disinfecting elevators, stairways, and railings.
- Cleaning luggage handling areas.
Performing these procedures between sailings helps prevent viruses from continuing onto the next cruise.
Norovirus Is the Most Common Cruise Ship Illness
Norovirus is responsible for the majority of gastrointestinal illness cases reported on cruise ships worldwide.
The virus spreads easily in environments where large groups of people share dining spaces, public areas, and entertainment venues.
However, outbreaks remain relatively rare when compared with the millions of passengers who cruise each year.
When incidents do occur, cruise lines typically act quickly to isolate cases and limit transmission.
A Temporary Challenge for a Brand-New Ship
Star Princess entered service only a few months ago and can carry more than 4,300 passengers at full capacity.
Although the outbreak represents an unfortunate early challenge for the ship, the quick response from crew members appears to have helped stabilize the situation.
Many passengers onboard have commented positively about how seriously the crew is taking sanitation and health precautions.
With the deep cleaning scheduled before the next cruise begins, future guests boarding in Fort Lauderdale should expect a ship that has been thoroughly cleaned and prepared for its next Caribbean journey.
