A norovirus outbreak has impacted over 100 people aboard AIDA Cruises’ AIDAdiva ship, according to a report from the Centers for Disease Control and Prevention (CDC).
At least 95 of the 2,007 passengers and six of the 640 crew members reported symptoms during the voyage, which included diarrhea and vomiting, the CDC noted.
The AIDAdiva is currently on a 133-day world cruise that began on November 10 in Hamburg, Germany.
The journey includes stops in the U.S., England, Mexico, Japan, South Africa, and more, with the cruise scheduled to return to Hamburg on March 23, 2026, according to the ship’s itinerary.
During the voyage, the ship had already visited Boston, New York, Miami, and Charleston, South Carolina, when the outbreak was reported on November 30.
In response to the outbreak, AIDA Cruises consulted with the CDC’s Vessel Sanitation Program to prevent further spread. Measures included isolating ill passengers and crew members, increasing cleaning and disinfection procedures, and collecting stool samples from those experiencing gastrointestinal symptoms for testing.
The CDC requires all cruise ships to report any gastrointestinal illness during sailings, and the agency noted that 21 norovirus outbreaks have already been reported on cruise ships since the beginning of 2025.
AIDA Cruises, whose parent company is Carnival Corporation, is based in Germany and has already announced plans for its next world cruise aboard the AIDAsol.
That 126-day sailing will run from October 18, 2026, to February 21, 2027, visiting 43 ports across 20 countries on four continents.
The norovirus outbreak aboard the AIDAdiva underscores the challenges cruise lines face in managing contagious illnesses while operating extensive global itineraries.
Crew and passengers alike were closely monitored, and the cruise line implemented CDC-recommended safety protocols to limit further cases.
