Another Royal Caribbean cruise outbreak hits 140+ passengers. Are outbreaks getting worse?

2025 has already seen as many cruise ship outbreaks as all of last year. Is this the new normal?
More than 140 passengers and crew members aboard Royal Caribbean's Navigator of the Seas fell ill with gastrointestinal symptoms during a week-long cruise that ended July 11, marking yet another outbreak in what's shaping up to be a particularly challenging year for the cruise industry.
The outbreak affected 134 of the ship's 3,914 passengers — roughly 3.4% of those aboard — along with seven crew members out of 1,266 total crew. Passengers experienced the familiar trio of cruise ship illness symptoms: vomiting, diarrhea, and abdominal cramps. The Navigator of the Seas had departed Los Angeles on July 4 for a round-trip voyage to Mexico, making three stops before returning to port, where the outbreak was officially reported to the Centers for Disease Control and Prevention.
What makes this outbreak particularly concerning isn't just the numbers — it's the broader trend. We're only halfway through 2025, and this incident brings the year's total cruise ship gastrointestinal outbreaks to 18, already matching the entire total for 2024. That's a significant jump from the 14 outbreaks recorded in 2023. Is this the future of cruising?
A troubling pattern in the U.S.
The CDC tracks these incidents carefully, but only reports outbreaks that meet specific criteria: the ship must be under Vessel Sanitation Program jurisdiction (operating voyages that include both U.S. and foreign ports) and at least 3% of passengers or crew must report gastrointestinal symptoms to the ship's medical staff. This means the Navigator of the Seas outbreak, at 3.4% of passengers affected, just barely crossed the threshold for public notification.
Most of these outbreaks stem from norovirus, the highly contagious stomach bug that spreads rapidly in enclosed environments. The CDC noted in April that "a newly dominant strain is currently associated with reported norovirus outbreaks on land," and ships typically mirror land-based outbreak patterns. This suggests the current surge may reflect broader public health trends rather than cruise-specific problems. But that's not great news, either.
For the record, Royal Caribbean implemented enhanced sanitation protocols and isolated sick passengers and crew members during the voyage. The company emphasized that "the health and safety of our guests, crew, and the communities we visit are our top priority," noting their cleaning procedures exceed public health guidelines. However, the CDC has yet to identify the causative agent behind this latest outbreak.
The streak continues — across all cruise lines
This isn't Royal Caribbean's first outbreak rodeo this year. The cruise line has been dealing with multiple outbreaks across its fleet, joining other major operators like Holland America Line, Princess Cruises, and Cunard in facing similar challenges. Earlier this year, a Cunard luxury liner experienced an outbreak affecting more than 240 passengers and crew during a monthlong international voyage, while Princess Cruises saw over 80 people fall ill during a 16-night cruise in February.
The timing of these outbreaks raises questions about whether cruise lines are adequately prepared for what appears to be a particularly virulent norovirus season. While companies have implemented enhanced cleaning protocols and isolation procedures, the close quarters and shared facilities aboard cruise ships create ideal conditions for rapid transmission of gastrointestinal illnesses.
Are cruises... actually safe?
Despite the alarming headlines, perspective matters. The Navigator of the Seas carried nearly 4,000 passengers, and while 134 falling ill sounds significant, it represents a relatively small percentage of the total. For comparison, norovirus outbreaks occur regularly on land — in schools, nursing homes, and restaurants — but cruise ships draw more attention because they're self-contained environments where outbreaks can be easily tracked and reported.
The CDC emphasizes that cruise ship outbreaks represent only 1% of all reported gastrointestinal outbreaks. However, the concentrated nature of cruise ship populations means that when outbreaks do occur, they can affect a substantial number of people in a short timeframe.
For prospective cruisers, the key is understanding that while these outbreaks are concerning, they remain relatively rare events. The cruise industry serves millions of passengers annually, and the vast majority complete their voyages without incident. That said, the uptick in reported outbreaks suggests passengers should be particularly vigilant about hand hygiene and other preventive measures, especially during peak norovirus seasons.
The real question isn't whether cruises are safe — they generally are, all things considered. Instead, we should be asking whether the industry is doing enough to adapt to evolving public health challenges (never mind sustainability) and whether current protocols are sufficient to handle increasingly virulent strains of common illnesses. Because in 2025, there's work to be done.
