Medical community concerned about alarming rise in Norovirus outbreaks on cruise ships.

The allure of the ocean, glamorous itineraries and the promise of carefree luxury have made cruise travel a long-time popular choice for vacationers.

However, a recent surge in outbreaks of Norovirus, a particularly persistent and contagious pathogen, has clouded the industry’s allure.


Why does Norovirus appear frequently on cruise ships?



Since the beginning of the year, a disturbing trend has emerged. There have been 13 outbreaks on six different cruise lines, according to the U.S. Centers for Disease Control and Prevention (CDC). The staggering figure is the highest rate of such outbreaks since 2012, when eight cruise lines saw 16 outbreaks for the year.


In light of these recent developments, it is imperative to explore and understand the nature of Norovirus—what it is, why it recurs on cruise ships, and its impact on the cruise industry. This article aims to shed light on these issues, reveal their complexity, and highlight ongoing responses.


The recent surge in Norovirus outbreaks has highlighted the need for vigilance and proper understanding of the issue, both for those planning dream vacations at sea, and for the cruise industry itself. Together, we can ensure that cruise ships continue to be places of relaxation and enjoyment, not breeding grounds for this troublesome virus.




What is Norovirus?


Sometimes called “winter vomiting sickness,” Norovirus is a highly contagious virus that can cause gastroenteritis, an inflammation of the stomach and intestines. Named after the city of Norwalk, Ohio, where an outbreak was first identified in 1968, Norovirus can cause severe vomiting, diarrhea, stomach cramps and, in some cases, severe dehydration, among other serious consequences .


Norovirus is usually spread through direct contact with an infected person, eating contaminated food or water, or touching surfaces or objects that have been contaminated with the virus.

One of the major challenges in containing Norovirus is that Norovirus can survive on various surfaces for considerable periods of time, making it easy to infect without knowing it.




Why does Norovirus appear frequently on cruise ships?


Highly contagious in close quarters

The design and operation of cruise ships often involves large groups of people living in close quarters, sharing dining areas, entertainment venues and public restrooms. This makes it easy for Norovirus to spread rapidly from person to person.


Rapid and massive outbreaks

When a case of Norovirus appears on a cruise ship, it can quickly lead to an outbreak affecting hundreds or even thousands of people. This can happen very quickly due to the enclosed nature of cruise ships and the frequent close contact between passengers and crew.


Contaminated food and water

Cruise ships are known for their extensive buffet and dining options. This provides an opportunity for the virus to spread if food or water is contaminated by an infected person or becomes contaminated through improper handling and storage.


Difficulty in proper sanitation

While cruise ships have strict sanitation protocols, the tenacity of Norovirus has compounded the problem. Norovirus can survive for days on surfaces and is resistant to many commonly used disinfectants


Disruption of planned activities

Norovirus outbreaks can severely disrupt cruise line programs and itineraries. Infected people must be quarantined, common areas may need to be closed for cleaning, and in severe cases, the cruise ship may even have to return to port.



The impact of Norovirus on the cruise industry


In response to the Norovirus threat, cruise lines have had to invest heavily in sanitation protocols, disease detection methods and passenger education .

In many cases, the outbreak has resulted in public relations challenges, decreased passenger satisfaction, and financial losses due to trip cancellations and medical expenses.


Additionally, the cruise industry tends to come under intense scrutiny following an outbreak, which can affect public perception and willingness to book cruises, ultimately affecting the industry’s bottom line.





The Norovirus threat on cruise ships is a serious problem with health and economic implications. The confined environment of a cruise ship combined with the highly contagious nature of the virus presents a formidable challenge.

Cruise lines, passengers, and health officials must remain vigilant and proactively informed to prevent and contain potential Norovirus outbreaks.

While the cruise industry has made great strides in improving sanitation protocols and disease prevention measures, the threat of Norovirus remains an ongoing concern to ensure the safety and well-being of all passengers at sea.
