A norovirus outbreak has sickened 120 people on a Holland America Line cruise. This includes 107 guests and 12 crew members on the Rotterdam ship. They were affected by vomiting and diarrhea. The ship is currently on a 12-day Panama Canal cruise. It left Fort Lauderdale, Florida, on February 2, 2025.
Details of the Outbreak
The Rotterdam carries 2,614 passengers. Of them, 107 guests reported feeling ill during the voyage. In addition, 12 crew members had symptoms. The Centers for Disease Control and Prevention (CDC) confirmed the illness was norovirus. This virus is common in crowded places, like cruise ships.
The cruise line quickly took action. A spokesperson said the cases were mild. Most people got better quickly. The line started extra cleaning measures. They disinfected public areas continuously. They also isolated sick passengers and crew members. This helped stop the virus from spreading.
How Norovirus Spreads
Norovirus spreads easily. It passes from person to person. It can also spread through contaminated food, water, or surfaces. Cruise ships are especially vulnerable because people share meals and spaces. Norovirus often spreads in winter when people stay indoors more.
Dr. Dean Winslow, a doctor at Stanford Medicine, explained that norovirus is common in places where people eat and drink together. These places include nursing homes, schools, and even hospitals. The virus causes discomfort but is usually not dangerous. Most people recover in a few days.
Response from Holland America
Holland America worked closely with the CDC. The line took quick action to contain the virus. The spokesperson said the company followed CDC guidelines. They cleaned high-touch surfaces frequently. The cruise line also isolated sick passengers to reduce contact with healthy ones. This helped to limit the spread.
The CDC supports the cruise line’s response. They work together to stop outbreaks like this one. The agency also reminded passengers to wash their hands often. Washing hands reduces the spread of norovirus. The CDC also recommends that cruise lines keep public spaces clean, especially dining areas.
Winter and Norovirus Outbreaks
The winter season sees more outbreaks of norovirus. People spend more time inside when it is cold. This helps the virus spread faster. However, while outbreaks happen often on cruise ships, they make up only 1% of all reported cases. The majority of outbreaks occur in places like schools and hospitals.
The CDC reports that this is the seventh outbreak of norovirus on a cruise in 2025. Last year, there were 18 outbreaks. Most of those were also caused by norovirus. The agency said the virus is not only common on cruises. It is a widespread problem in many settings. While norovirus is very contagious, it is not usually deadly. However, it can cause severe discomfort.
Other Affected Cruises
The Rotterdam is not the only cruise affected by norovirus recently. Just last December, the same ship had a similar outbreak. That incident was also caused by norovirus. This highlights how common the illness is on cruise ships.
The cruise line has made efforts to prevent future outbreaks. They now have more frequent cleaning schedules. They also use better cleaning tools. These changes should help reduce the chance of illness on future cruises.
Public Health and Cruise Ship Safety
The Rotterdam’s outbreak brings attention to the importance of public health on cruise ships. Large groups of people in close quarters make it easier for viruses to spread. The CDC’s role is crucial in overseeing the cleanliness of ships. They ensure cruise lines take steps to reduce the spread of illness.
One way to keep people safe is by making sure cruise lines have strong health measures in place. The CDC encourages cruise lines to use new technology to clean more effectively. Some ships now use ultraviolet lights to clean areas faster and better. Other ships have improved air filtration systems to help reduce the spread of germs.
While the norovirus outbreak on the Rotterdam caused concern, it was managed quickly. The cruise line took immediate steps to stop the spread of the virus. The CDC provided support and advice. Together, they minimized the impact of the illness. The outbreak serves as a reminder of the importance of hygiene and safety on cruise ships.
