2025 Sets Record for Cruise Ship Norovirus Outbreaks - Here's What You Need to Know

The buffet giveth, and the buffet taketh away.

There’s a certain irony to cruise ship dining. You pay thousands of dollars for an all-inclusive vacation with unlimited food, and then a microscopic virus turns that 24-hour buffet into your worst enemy.

Welcome to 2025, officially the worst year on record for cruise ship gastrointestinal outbreaks.

The Numbers Are Ugly

According to Cruise Law News, 2025 saw 20 gastrointestinal outbreaks reported across cruise lines – the highest number since the CDC began publicly tracking this data in 1994.

Let that sink in. Thirty years of data, and 2025 is the champion of cruise ship stomach bugs.

The previous record? 2024, with 18 outbreaks. Third place goes to 2012, with 16. So not only did 2025 break the record, but the last two years represent the two worst on record.

The cruise industry is crushing it in all the wrong categories.

The Outbreak Hits

Let’s run through some of the major incidents that contributed to this dubious milestone:

Holland America Rotterdam (December 2025 – January 2026): According to Food Safety News, the CDC reported 94 people fell ill between December 28, 2025, and January 9, 2026. That’s 85 passengers and 9 crew members spending their holiday over the toilet instead of at the captain’s dinner.

Royal Caribbean Serenade of the Seas (October 2025): NBC News reported that at least 94 passengers and crew were sickened aboard this ship – the third outbreak on a Royal Caribbean vessel in 2025.

Oceania Insignia (October 2025): According to CDC data, 74 passengers and 1 crew member came down with norovirus, affecting 11.6% of passengers. This was Oceania Cruises’ first reported outbreak.

Princess Coral Princess (March 2025): Food Safety News reported 69 passengers and 13 crew members fell ill with diarrhea and vomiting as the predominant symptoms.

Viking Polaris (April 2025): According to Food Poisoning News, over 30 individuals – 28 passengers and 4 crew members – were affected during a two-week voyage from Toronto to New York.

And that’s not even all of them. Holland America alone had seven outbreaks in 2025, including three on the Rotterdam and two on the Eurodam.

What’s Causing This?

If you’re wondering why 2025 was so bad for cruise ship outbreaks, you’re not alone. A few factors are likely at play:

1. Broader norovirus spike: The cruise ship outbreaks mirror a larger national trend. According to the CDC’s NoroSTAT network, the U.S. recorded 1,078 norovirus outbreaks from August 2024 to January 2025 – nearly double the 557 from the same period the previous year. Whatever’s happening isn’t cruise-specific.

2. Full capacity sailings: After years of reduced capacity due to COVID-19, cruise ships are back to being packed. More people = more potential carriers = more opportunities for spread.

3. Dining behaviors: Buffets, communal seating, and the general cruise ship culture of “eat everything in sight” create perfect conditions for a virus that spreads through contaminated surfaces and food.

4. Reporting improvements: It’s possible that better detection and reporting are catching outbreaks that would have flown under the radar in previous years. But that seems unlikely to explain a 30-year record.

How Norovirus Spreads (And It’s Gross)

Time for some unpleasant science. Norovirus spreads via the “fecal-oral route,” which is exactly as disgusting as it sounds.

The virus sheds in astronomical numbers when an infected person has diarrhea or vomits. Those particles get on surfaces – bathroom fixtures, handrails, buffet serving spoons, elevator buttons. Someone touches the surface, then touches their mouth (or their food), and boom – they’re next.

Norovirus is also incredibly hardy. It can survive on surfaces for days or weeks. It’s resistant to many common disinfectants. And it only takes a tiny number of viral particles – as few as 18 – to cause infection.

On a cruise ship with 3,000+ passengers touching the same surfaces and eating from the same buffets, it’s almost remarkable that outbreaks don’t happen MORE often.

What Cruise Lines Are Doing

To their credit, cruise lines take norovirus seriously. The sanitation measures on most ships include:

Hand sanitizer stations everywhere (and crew who watch to make sure you use them)
Regular deep cleaning of high-touch surfaces
Enhanced food handling protocols
Isolation of sick passengers
Sometimes closing buffets in favor of served meals during outbreaks

When an outbreak is detected, ships typically increase cleaning frequency, may quarantine affected passengers to their cabins, and in some cases modify dining operations entirely.

But norovirus is persistent. Even the best protocols can’t stop a virus that spreads this efficiently.

How to Protect Yourself

If you’re cruising in 2025 (or any year), here’s how to minimize your risk:

1. Wash your hands obsessively. Hand sanitizer is good, but soap and water is better for norovirus. Wash for at least 20 seconds before every meal and after touching anything in public areas.

2. Don’t touch your face. Easier said than done, but try. Your hands pick up contamination; your face is the entry point.

3. Skip the buffet if there’s an outbreak. If you hear about people getting sick on your ship, switch to restaurant-style dining where food is served to you.

4. Use the sanitizer. Those crew members asking you to use sanitizer before entering the dining room? They’re doing it for a reason. Comply enthusiastically.

5. If you feel sick, report it. Trying to hide symptoms so you don’t miss that port day is how outbreaks spread. Stay in your cabin and call medical.

6. Bring Lysol wipes. Give your cabin a once-over when you arrive. Wipe down light switches, door handles, TV remotes, and phone handsets.

The Cruise Line Scoreboard

For those keeping track, here’s which lines had the most reported outbreaks in 2025:

Holland America: 7 outbreaks (including 3 on Rotterdam)
Royal Caribbean: 3 outbreaks
Princess: Multiple outbreaks
Viking: At least 1 outbreak
Oceania: 1 outbreak (their first)

This doesn’t necessarily mean these lines have worse sanitation – larger fleets mean more chances for outbreaks, and ships that carry more passengers have more potential cases.

The Takeaway

The record-setting norovirus year of 2025 is a reminder that cruise ships, for all their luxury and engineering marvels, are essentially floating petri dishes when it comes to gastrointestinal illness.

That shouldn’t stop you from cruising. Millions of people sail every year without incident. But it should make you vigilant about hygiene.

Wash your hands. Use the sanitizer. Maybe skip that seventh trip to the dessert station.

Your stomach will thank you.
