AIDA Cruises Norovirus Outbreak Affects More Than 100 People Onboard
Recently, AIDA Cruises had a rocky start to its world voyage when more than 100 people onboard caught norovirus early on in the trip.
It didn’t take long for the illness to make its way through the shared spaces, and this AIDA Cruises norovirus outbreak quickly became one of the most talked-about cruise health stories of the season.
What We Know So Far
During the early stretch of AIDAdiva’s 133-day itinerary, more than 100 passengers and crew members reported norovirus symptoms on the cruise, like vomiting and diarrhea.
The ship had just departed Hamburg and was scheduled to visit England, the United States, Mexico, Costa Rica, and other ports.
The cruise line moved quickly to add extra cleaning, increase disinfection, and isolate anyone who was sick.
Thankfully, those steps helped slow the AIDAdiva outbreak, and case numbers have already started to drop.
How Many People Got Sick
AIDA Cruises confirmed that 95 guests and 6 crew members got sick throughout the voyage.
The ship had a total of 2,007 guests onboard, so most of the passengers were unaffected.
Still, norovirus is known for spreading fast, especially in places where people eat and live close together.
What We Know About the Outbreak
The CDC recorded this as one of several cruise ship illnesses in 2025. So far this year, the CDC cruise ship outbreaks list includes 21 gastrointestinal events that met the reporting threshold, with norovirus being the majority.
This follows similar patterns from 2024 and 2023, when the virus also accounted for the majority of the cases reported at sea.
Public health experts say ships often reflect what’s happening on land, and this year’s norovirus season has been particularly active.
How AIDA Responded Onboard
Once reports of the illness began to rise, the crew increased their sanitation efforts throughout the ship. High-touch areas were cleaned more often, and additional hygiene reminders were posted around the vessel.
Sick passengers and crew members were asked to stay in their cabins until they were symptom-free.
These steps are common during gastrointestinal outbreaks at sea and are designed to help protect travelers while keeping the itinerary as stable as possible.
Why Cruise Ships See Norovirus More Often
Norovirus thrives in environments where many people share dining spaces, bathrooms, and other public areas. Cruise ships, schools, nursing homes, and daycare centers often report the most outbreaks for this reason.
Experts say that many norovirus cases in everyday communities go unreported, but outbreaks on cruise ships are more likely to be detected and documented because the setting is more controlled.
What We Can Take Away From This
If you have a cruise planned, norovirus doesn’t have to stop you from enjoying your trip.
Handwashing with soap and water, avoiding shared food when you feel unwell, and reporting symptoms early on can make a big difference.
Cruise lines also have strong cleaning protocols in place during peak illness seasons. Still, outbreaks like this one remind us how quickly illness can move through shared spaces, but they also reflect how effective early action and added hygiene measures can be.
