Norovirus Outbreaks on Cruise Ships in December
Norovirus Sickens Hundreds on Three Cruise Ships: CDC | Health
In December 2024, the U.S. Centers for Disease Control and Prevention (CDC) reported a concerning trend: norovirus outbreaks on three different cruise ships. These outbreaks have affected over 300 passengers and crew members, raising alarms about health safety on cruise lines. Norovirus, often referred to as the “cruise ship virus,” is notorious for causing gastrointestinal illness. It spreads easily in crowded environments, making cruise ships particularly vulnerable. This article delves into the details of these outbreaks, their implications, and the measures taken to address them.
Overview of the Outbreaks
In total, 301 individuals fell ill due to norovirus outbreaks on three cruise ships in December. This month marked the only time in 2024 that the CDC reported multiple confirmed outbreaks on cruise ships. The affected vessels included Holland America’s Rotterdam and Zuiderdam, as well as Princess Cruises’ Ruby Princess. Passengers and crew members primarily experienced symptoms such as diarrhea and vomiting, which are common indicators of norovirus infection.
The Rotterdam, which was concluding its Caribbean voyage, reported the highest number of cases. Out of 2,192 passengers, 83 were sick, along with 12 of the 953 crew members. A spokesperson for Holland America emphasized that the health and safety of guests and crew are their top priorities. They noted that the cases were mostly mild and resolved quickly. To combat the outbreak, the cruise line implemented additional cleaning and disinfection protocols. Sick individuals were isolated to prevent further spread.

The Zuiderdam also faced a significant outbreak earlier in December. During a voyage from December 4 to 11, 87 out of 1,923 passengers and four of the 757 crew members reported illness. Meanwhile, the Ruby Princess, which sailed from San Francisco to Hawaii, reported 103 sick passengers and 12 crew members out of 3,001. Princess Cruises has not publicly commented on the situation.
The Challenges of Containing Norovirus
Norovirus is particularly challenging to control on cruise ships. The close living quarters, shared dining areas, and rapid turnover of passengers create an environment where the virus can spread quickly. According to the CDC, norovirus can be introduced to a ship through contaminated food or water, or by passengers who were infected while ashore. Once on board, the virus can easily infect others, leading to outbreaks.
The CDC notes that there are approximately 2,500 reported norovirus outbreaks in the United States each year. While cruise ships account for a small percentage of these outbreaks, they often receive significant media attention due to the nature of the incidents. The CDC has implemented strict guidelines for cruise lines to follow in order to minimize the risk of outbreaks. These include enhanced sanitation measures, passenger education on hygiene practices, and protocols for isolating sick individuals.
Despite these measures, outbreaks can still occur. The recent incidents highlight the importance of vigilance and preparedness among cruise lines. Passengers should be aware of the risks and take precautions, such as frequent handwashing and avoiding close contact with sick individuals.
