If you're planning a cruise this summer, you'll have to worry about more than just auto-gratuity increases: the Centers for Disease Control and Prevention (CDC) has reported a significant uptick in gastrointestinal illness outbreaks on cruise ships in 2025. So far, 16 outbreaks have been reported—10 of them caused by norovirus. That's the highly contagious bug that can turn your dream vacation into a queasy nightmare.
In the most recent outbreak, more than 150 passengers and crew aboard Holland America Line’s Eurodam fell ill. And with the year not even halfway through, 2025 is already trending worse than 2024, which saw 18 outbreaks in total.
Why are cruise ships such hotspots? Tight quarters, shared buffets and lots of contact with new people. Cruises are one big petri dish for norovirus. The CDC’s Vessel Sanitation Program (VSP), despite recent staffing cuts, is still tracking outbreaks and encouraging transparency from cruise lines.
The CDC says you can still cruise, but offers tips for protecting yourself. Start with the basics: wash your hands. A lot. Before eating, after using the restroom and anytime you touch shared surfaces. Hand sanitizer is helpful, but soap and water are your best defense.
If you're feeling sick, report it to the ship’s medical center right away. Early detection helps staff contain outbreaks before they spread. And don’t be shy about steering clear of passengers who seem under the weather—social distancing isn’t just for pandemics.
Finally, disinfect your cabin’s high-touch surfaces with bleach-based wipes, and skip the buffet if it looks suspect. Norovirus may be a more common part of cruise life this summer, but with a little vigilance, you can make sure you enjoy smooth sailing.
