Royal Caribbean Group hired new internal public health inspectors to help the ships improve their public health practices. The Norovirus Eradication Campaign was launched in 2023 on Royal Caribbean International and Celebrity Cruises vessels with the ultimate goal of eliminating transmission of norovirus on its ships. “Norovirus is one of the few viruses that doesn’t get deactivated by alcohol. You actually need to use soap and water to physically destroy it and remove it from your hands,” Ostrosky previously told TODAY.com. Exposure to less than 100 norovirus particles can make someone sick, and infected people typically shed billions of particles, according to the CDC.
Incorrectly Called the Cruise Ship Disease
As post-pandemic travel surges and millions of Americans return to cruise ships, an increasing number of cruise lines are reporting outbreaks at sea. Norovirus can be especially challenging to control on cruise ships because of the close living quarters, shared dining areas, and rapid turnover of passengers. When the ship docks, norovirus can be brought on board in contaminated food or water or by passengers who were infected while ashore. Repeated outbreaks on consecutive cruises may also result from infected crew or environmental contamination.
Norovirus outbreaks on cruise ships surge to decade-high levels: How to avoid the stomach bug
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. Norovirus, sometimes referred to as the “winter vomiting bug,” is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines.
Norovirus Cases Are Rising on Cruises. Here’s How You Can Stay Safe
Norovirus infects between 19 million and 21 million Americans annually, the CDC reports. The most recent occurred in June on a Viking Cruises ship from Iceland that docked in New York, where 110 passengers and eight crew members fell ill. Land-based operations ("Field Service") include mobile clinics providing screening for potential surgery patients, healthcare, dental care, also mental health programs, infrastructure projects.
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. Public health officials track illnesses on cruise ships so “outbreaks are found and reported more quickly on a cruise ship than on land,” the C.D.C. said. Some of the world's most famous passenger ships are listed in the virus outbreak statistics, yet one hears so little of it in mass media news.
A norovirus outbreak can cause significant disruption to the planned activities and itineraries of a cruise. Infected individuals must be isolated, common areas may need to be closed for cleaning, and in severe cases, the ship may even have to return to port. In light of these recent developments, it’s imperative to explore and understand the nature of Norovirus — what it is, why it’s a recurring issue aboard cruise ships, and its impact on the cruise industry. This article aims to shed light on these matters, unpacking the complexities of the problem, and highlighting the steps that are being taken to address it. Some people find getting tested for norovirus embarrassing, while others only have stomach virus symptoms for a few days and do not seek medical care during that time.

When the Covid pandemic hit, the CDC made a travel health notice advising against cruise ship travel. However, in March 2022 the agency dropped the health notice, though it strongly urged against cruising without a booster shot. 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.

Using a Smartphone to Detect Norovirus (Winter Vomiting Bug)
As part of the program, ships are required to adhere to stringent health and safety protocols that dictate everything from the cleaning of high-touch areas to how food is stored in freezers, refrigerators and galleys. On ships where outbreaks occur, the crew conducts a deep cleaning of the ship after passengers have disembarked and before the next sailing begins. In cases where outbreaks are particularly severe, subsequent sailings could be canceled to allow for more thorough sanitization. According to data compiled by the Centers for Disease Control and Prevention (CDC), there have been 13 outbreaks across six different cruise lines. This alarming number marks the highest incidence of such outbreaks since 2012 when there were 16 across eight lines over the entire year.
Common Settings of Norovirus Outbreaks
Seasickness manifests in different ways and is always a result of the body's attempt to correct for the conflicting inputs received from its senses. Common symptoms are cold sweat, dizziness, drowsiness, headache, nausea. When such symptoms are noticed, passengers should take precautions to prevent intensifying the disorientation. Obviously, the first thing is to go to the ship's infirmary (medical center) and contact the doctor.
The C.D.C. said that, as of Thursday, 129 passengers and 25 crew members had reported being ill on the ship. The agency said 1,824 passengers and 967 crew members were aboard at the time of the outbreak. In cases of severe emergencies, passengers with life-threatening illnesses or injuries are evacuated off the ship - either by boat (if in or near seaport) or by rescue helicopter dispatched from nearest coast guard or other station. In some cases, nearby ships with better medical facilities may assist. If seasickness symptoms are accompanied by diarrhea or fever, passengers should immediately seek medical treatment for Norovirus and avoid spreading the illness to others.
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. Lastly, “if you see someone sick like vomiting or having diarrhea, remove yourself from the area and notify cruise staff if they are not already aware,” Boden-Albala says.
The CDC says the most common symptoms of norovirus are diarrhea, vomiting, nausea, and stomach pain. The CDC estimates only about 1% of all annual U.S. norovirus cases happen on cruise ships. The numbers are greatest in nursing homes, hospitals, schools and restaurants, which collectively account for about 91% of cases. Infected passengers who don't wash their hands after coughing, sneezing or using the restroom are the reason those surfaces become contaminated in the first place.
In most cruise ship hospitals, some supplies and medications are provided to passengers and crew for free - like aspirin, seasickness pills, small bandages. For passengers with health concerns, medical care on cruise ships is a vital part of their travel planning. Most cruise vessels are equipped with either basic infirmary (a small clinic) or larger hospital where sick or injured passengers are treated and cared for by contractor physicians and nurses on 24-hour duty. The virus can be introduced into healthcare facilities by infected patients, staff, visitors, or contaminated foods. Norovirus illnesses can be more severe and occasionally even deadly in patients in hospitals or long-term care facilities when compared with healthy people. That means data for norovirus on cruise ships is more readily available than for other entities.
It's a very common, highly contagious, ruthlessly efficient and uncomfortably bad virus affecting the stomach and large intestines. Often called "stomach flu" (the med term is "Gastroenteritis") the infection results in massive vomiting and diarrhea. Sickness outbreaks are considered as such if the percentage of infected people is over 3%. The virus is not seasonal and usually not serious (in medical terms). It hits 1 in 5 people annually and is the cause of ~50% of all foodborne illness outbreaks in the USA and for ~90% of all non-bacterial gastroenteritis worldwide. Specifically, the medical staff from each cruise ship must submit a report with the number of ill passengers within 24 to 36 hours of its arrival at a U.S. port from a foreign port, even when no cases of gastrointestinal illness are present.

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. Norovirus is referred to as "the stomach flu", and is easily spread from person to person.
