This means Norovirus outbreaks are reported more quickly on ships than on land. Just for comparison, the virus can afflict as many as 3000 people per day in only one big city, which is about the passenger capacity of a typical modern cruiser. ▪ While the virus has garnered the nickname “cruise ship virus,” in reality, norovirus outbreaks on cruise ships account for only 1% of all reported norovirus outbreaks, the CDC says. In fact, acute gastrointestinal illness is fairly uncommon on cruise ships, the agency says. Through its Vessel Sanitation Program, the CDC inspects cruise ships, monitors illness, trains crew and provides public health information. The agency releases information on outbreaks when 3 percent or more of passengers or crew report symptoms to medical staff on board.

▪ You can get norovirus in a variety of ways, such as by eating or drinking contaminated food and drinks, touching an infected surface and then touching your mouth or having direct contact with someone ill from the virus, according to the CDC. Mathis says older passengers and others traveling with family face a risk from others in their party. For example, if grandchildren aren’t careful hand-washers, they can easily infect their grandparents and others. If you'd like to check out the outbreak information, you can find a detailed list of ships that have had acute gastroenteritis outbreaks (many of which were caused by norovirus), listed by year, about halfway down the CDC's outbreak page. People with ARI should be advised of the importance of covering coughs and sneezes and keeping hands clean because respiratory viruses may be shed after the isolation period ends. Fever (a temperature of 100°F [37.8°C] or higher) will not always be present in people with influenza, COVID-19, or RSV.

Nearly 1,700 passengers have come down with the virus, which causes vomiting, nausea, diarrhea and stomach pain. Not only does it take the joy out of vacation, keeping passengers confined to their stateroom, but for older travelers, there’s a concern of dehydration, doctors say. Norovirus spreads easily in close quarters, such as those found on cruise ships. Such viral/bacterial outbreak incidents affect the vacation experience of thousands of people, being packed up in a floating resort for many days on end.
Seasickness on cruise ships
A few years ago an experimental Norovirus vaccine (applied as nasal spray) was developed by the "Center for Infectious Diseases and Vaccinology" (Arizona State University). Numerous studies confirm that a quick application of hand sanitizer doesn't kill the Norovirus. It takes about 30 sec of hard rubbing with hot water and soap (including under the nails) to wash it.

Find out why norovirus is unfairly labeled a cruise ship illness, what cruise lines do to minimize onboard spread and whether you should be worried about it on your next voyage. An excessive number of news reports exist for norovirus cases on ships, making it seem to the unsuspecting public that cruise vessels are dirty or you're likely to get sick if you sail. Infection prevention and control (IPC) are critical to reducing the spread of ARI. Each cruise ship should maintain a written Infection Prevention and Control Plan (IPCP) that details standard procedures and policies to specifically address infection control and cleaning/disinfection procedures to reduce the spread of ARI. Travelers with ARI who board, as well as those who become sick with ARI onboard, should be identified and tested as soon as possible to minimize transmission of respiratory viruses.

Norovirus Cases On Cruise Ships Skyrocket: Here’s Why—And How To Avoid Getting Sick.

This is a virus that is not only passed through respiratory pathways but also environmental pathways as well. And recent data from the CDC has noted that over 15% of norovirus tests are coming back positive. "MSC Cruises rigorously adheres to health protocols, and the results of this inspection do not reflect the brand's high standards," the person added. Likewise, Mathis says vacationers shouldn’t let the fear of norovirus keep them from taking a vacation.
How common is it?
The table below provides disease-specific recommendations for persons on board with COVID-19, influenza, or RSV and those exposed (i.e., contacts). To reduce the likelihood of onboard transmission of SARS-CoV-2, pre-embarkation testing is recommended for all passengers, including those on back-to-back sailings [4]. Completion of testing closer to the time of embarkation (within 1 to 2 days) maximizes the benefit of preventing introduction of infectious persons onboard.
However, unlike on land, most basic travel insurance policies don't cover medical treatments on cruise ships as they are not from the patient's primary caregiver. Purchasing cruise travel insurance with health coverage (medical clauses) is highly recommended. A cruise ship's medical facility can treat only passengers experiencing minor health issues - seasickness, scrapes, sunburns, etc. More severe medical emergencies can't be handled on the ship and usually require medevacs. Coast guard helicopter teams fly to the ship, hoist the passenger (accompanied by a spouse/relative and a crew nurse) and fly them to the nearest land hospital.
Medical Evaluation and Management
In 2013, the number of reported illness outbreaks on cruise ships was 22. The total number of infected was 2385 (of those 2249 passengers and 136 crew). In 2014, the number of reported illness outbreaks on cruise ships was 17. The total number of infected was 3559 (of those 3354 passengers and 205 crew). In 2015, the number of reported illness outbreaks on cruise ships was 23.
Of those 127 million cruisers, 26,450 reported symptoms of gastrointestinal illness while on board. It sounds like a large number, but it amounts to just 0.02% (two one-hundredths of one percent) of cruisers throughout those 14 years, with the total number of cases decreasing from 4,507 in 2006 to 1,201 in 2019. Norovirus is highly contagious and spreads when you touch a contaminated surface and then put your fingers in or near your mouth, such as when eating without washing your hands. It's also frequently spread through contaminated food, sometimes earning it the nickname "food poisoning," even though there are many pathogens that can cause foodborne illnesses. You might also hear it generically called a stomach bug or the stomach flu despite the fact that noroviruses are not the same as flu viruses. Here are listed latest cruise ship Norovirus outbreaks on passenger ships, with information what is and how to avoid Norovirus on cruise ships, CDC reports, and news updates.
People also are more likely to get sick now since pandemic restrictions have been lifted. For the past few years, people have not been exposed to as many common viruses and illnesses and now that exposure is rising, illnesses are bound to rise as well. The CDC logged 14 cruise ship outbreaks that met its threshold for public notification in 2023, more than any year between 2017 and 2019.
Norovirus cases have spiked across the United States this year, which some experts say is the result of ending COVID-19 restrictions. In a study of acute gastroenteritis cases from 2006 to 2019 (before the cruise industry's COVID-19 shutdown), the CDC found that the number of cases on ships decreased over those 14 years. It also noted that the number of cases tends to be higher on larger ships and on voyages of a week or longer. Cruise lines employ crews dedicated to keeping public areas and high-touch surfaces clean. Galley crews and waiters receive extensive training on food safety and handling.
Hospital ships are designated as floating medical facilities (hospitals). Generally, Zika is a mosquito-borne virus spread by Aedes aegypti (aka "yellow fever mosquito") and Aedes albopictus (aka "Asian tiger mosquito"). However, it became "cruise virus" since the decease can also result from intrauterine (contraceptive device), sexual intercourse, blood transfusion, lab exposure, organ/tissue transplantation, breast milk transmission.
Zika symptoms are fever, skin rash, pain in joints, conjunctivitis (pink eye). An "illness outbreak" is considered when 3% or more of all passengers report symptoms to the ship's med staff. The following "health advisory" list of recommended actions is often issued during gastrointestinal illness outbreak or on embarkation day (of the next scheduled voyage). It has important suggestions on how to avoid spreading the cruise ship virus infection. While cruise ships have strict sanitation practices, the resilience of norovirus complicates matters. The virus can survive for days on surfaces and is resistant to many common disinfectants, making it challenging to eliminate once an outbreak has occurred.
