The CDC Just Confirmed a Norovirus Outbreak on Holland America’s Rotterdam—And This Is the SECOND Time in 11 Months

The Centers for Disease Control and Prevention has confirmed what cruise passengers dread most: a norovirus outbreak aboard a cruise ship. And if you’ve been following Holland America Line, this news might feel like déjà vu—because it’s happening on the same ship that saw an outbreak less than a year ago.

According to NBC News, 81 passengers and 8 crew members fell ill with gastrointestinal symptoms during a 13-day Panama Canal and Caribbean voyage aboard the MS Rotterdam. The ship departed from Fort Lauderdale on December 28 and returned on January 10, 2026.

The Numbers Tell a Concerning Story

Out of 2,593 passengers and 1,005 crew members aboard, 89 people experienced the telltale symptoms of norovirus: vomiting and diarrhea. While that represents just over 3 percent of those onboard, it’s enough to trigger CDC protocols and raise questions about why this keeps happening on the same vessel.

Holland America Line reported the outbreak to the CDC’s Vessel Sanitation Program on January 8—the day before the voyage ended—and emphasized that “the health of our guests and crew is a top priority.” The cruise line noted that cases were “mostly mild and quickly resolved,” but that didn’t prevent the ship from requiring comprehensive sanitization upon its return to Port Everglades.

Why This Matters: Rotterdam’s Troubling Pattern

Here’s what makes this outbreak particularly newsworthy: this is the second norovirus outbreak aboard the Rotterdam in just 11 months. In February 2025, the same ship experienced an outbreak that sickened 169 people—nearly double the number affected in this latest incident.

That pattern should concern anyone considering booking a cruise on this vessel. While norovirus outbreaks can happen on any cruise ship (the CDC recorded 22 gastrointestinal illness outbreaks on cruise ships in 2025, with 17 attributed to norovirus), having two outbreaks on the same ship within a year suggests something more systemic might be at play.

Even more troubling: Holland America Line accounted for 7 outbreak incidents in 2025—more than any other cruise line—according to CDC data.

What Holland America Did in Response

Credit where it’s due: Holland America Line followed proper protocols once the outbreak was confirmed. The cruise line isolated affected passengers and crew members, increased cleaning and disinfection procedures, and collected stool specimens for laboratory testing to confirm the presence of norovirus.

The ship’s crew also consulted directly with the CDC’s Vessel Sanitation Program regarding enhanced sanitation cleaning procedures. And to prevent the outbreak from continuing into the next sailing, Holland America delayed embarkation for passengers boarding on January 9, allowing extra time for deep cleaning and sanitization.

The Rotterdam has since departed Port Everglades on a 9-night Southern Caribbean voyage visiting Curaçao, Bonaire, Aruba, and Half Moon Cay.

What Cruisers Need to Know

Norovirus is extremely contagious and spreads easily in close quarters—which makes cruise ships particularly vulnerable. The virus causes inflammation of the stomach and intestines, leading to vomiting, diarrhea, and stomach pain. Most people recover within 1 to 3 days, but the illness can be severe for young children, older adults, and people with weakened immune systems.

The best defense is aggressive hand hygiene. Norovirus is resistant to alcohol-based hand sanitizers, so frequent handwashing with soap and water is essential—especially before eating and after using the restroom.

If you’re booking a cruise, it’s worth checking the CDC’s Vessel Sanitation Program website, which tracks outbreaks and sanitation scores for cruise ships. While any ship can experience an outbreak, patterns matter—and the Rotterdam’s recent history raises legitimate concerns about whether underlying sanitation issues need to be addressed.

The Bottom Line

Norovirus outbreaks are an unfortunate reality of cruise travel, but two outbreaks on the same ship in less than a year crosses the line from bad luck to troubling pattern. Holland America Line deserves credit for following CDC protocols and delaying the next sailing to ensure proper sanitization, but cruisers considering the Rotterdam should be aware of this vessel’s recent history.

If you’re booked on an upcoming Rotterdam sailing, practice extra vigilance with hand hygiene and avoid self-serve buffets if possible. And if you start experiencing symptoms, report them to medical staff immediately—not just for your own health, but to help prevent the virus from spreading to others.

Because nobody wants their vacation memories to include a stomach bug.
