Norovirus outbreaks on cruise ships in 2024

Cruise norovirus outbreaks updates.

Norovirus on ships is spread through contaminated water, foods and surfaces (public restrooms, railings, doorknobs, handles, board games-cards-puzzles-toys, etc). Norovirus withstands chlorine, prolonged exposure outside the body, as well as temperature extremes. Like a virus, Norwalk can't be effectively treated with antibiotics, making it extremely difficult to eliminate in closed environments - like cruise vessels.

Norovirus may incubate up to 48 hours before the symptoms appear. This makes it difficult to restrict an outbreak. Noro symptoms include nausea, vomiting (kids more than adults, abdominal cramps, diarrhea, general weakness, low fever, headache, muscle aches. The illness could last up to 5 days (depending on the person's age, general health, and severity of the exposure to the virus. Recovered patients can still spread the virus for up to 2 weeks.

Quarantining the ill passengers and crew to their cabins is mandatory (at least for 48 hours) to slow the outbreak's spread. Failing to comply with the crew's orders results in fines or even discharge from the ship.

CruiseMapper's Norovirus survey is based on official data from CDC.gov (USA's "Centers for Disease Control and Prevention"). CDC's "Vessel Sanitation Program" assists the cruise tourism industry in preventing and controlling the transmission and spread of gastrointestinal illnesses (Norovirus, ETEC) on passenger ships calling on US seaports.

This program operates under the authority of the Public Health Service Act (fda.gov, "Quarantine and Inspection Regulations to Control Communicable Diseases"). CDC sanitation inspections on passenger ships are conducted twice a year. Scores of 86 are considered passing. Among the issues that CDC health inspectors usually find on board and report are:

• food debris
• dead insects
• insect droppings
• records indicating crewmembers (including cooks and galley staff) working while sick (suffering from gastrointestinal disorders or with acute gastroenteritis/AGE symptoms)
• cracked/corroded equipment
• soiled cutting boards
• food served undercooked
• lack of safety instruction signs.

CDC cruise ship Norovirus reports

Cruise ship outbreaks are reported (posted on the CDC website) when the illness incident meets the following criteria:

• The ship falls within the purview of the Vessel Sanitation Program (VSP). This means if it carries 13+ passengers and has a foreign cruise itinerary with US ports of call in it. Keep in mind, that most departures are from US-based home ports.
• The ship cruise itinerary length is between 3 and 21 days,
• The ship carries 100+ passengers.
• The percentage of infected passengers or crew (cases reported to the ship's med staff) during the cruise is 3% or more. This means small outbreaks on cruise ships will not be reported to the CDC.

CDC cruise ship inspection fees are payable by the shipowner. Fees are based on the vessel's size. VSP doesn't charge fees for consultations related to shipping facilities renovations or new ships. Inspection fees are as follows.

• Small ships (under 3000 GT/gross tons) pay USD 1500 per inspection.
• Small ships (between 3000-15000 GT) pay USD 3000 per inspection.
• Medium ships (between 15000-30000 GT) pay USD 6000 per inspection.
• Large ships (between 30000-60000 GT) pay USD 9000 per inspection.
• Extra-large ships (between 60000-120000 GT) pay USD 12000 per inspection.
• Mega-liners (above 120000 GT) pay USD 18000 per inspection.

Note: When the itinerary doesn't include US cruise ports, the ship is not required to report to CDC, thus no official illness outbreak report would be issued.

CDC ship illness outbreak investigations

VSP (abbrev "Vessel Sanitation Program") monitors CDC's observations on illness patterns for GI (gastrointestinal) outbreaks on passenger shipping vessels ( ferries and cruise ships ).

• VSP conducts outbreak investigations only in cases with 3% or more passengers or crew reported sick with GI symptoms. VSP may also conduct outbreak investigations in cases of unusual GI illness patterns (even if the rate is less than 3%).
• VSP conducts outbreak investigations only on vessels visiting ports in the USA or which are within 15 days of arriving at a US port.
• When an outbreak occurs, VSP asks for ship logs and infirmary records of reported GI cases (symptoms and timing) and illness distribution (among passengers/crew, during each day of the cruise).
• VSP staff usually boards the vessel for epidemiological assessment, interviews, distribution and analysis of illness questionnaires, monitoring cleaning procedures.
• Lab investigations - the onboard med staff often collects stool, vomit, blood specimens, which are then sent to land-based labs to confirm the illness cause.

During the onboard illness outbreak, VSP requires the cruise company to activate the "Outbreak Prevention and Response Plan" (vessel's response to illness cases).

During an outbreak:

• Cleaning and disinfection frequencies are Increased.
• Self-service buffets are stopped.
• All infected (pax/crew) are quarantined to their staterooms/cabins
• Clinical specimens are collected for analysis.
• Daily updates are provided to VSP (cases counts and measures reports)
• All passengers and crew are alerted of the illness.
• Upon boarding on the next scheduled cruise, passengers are notified about the previous voyage's outbreak.
• Occasionally, VSP requires the company to notify port authorities and also to perform cleaning and disinfection in cruise port terminal buildings.

Illness outbreaks on cruise ships (annual statistics)

The following statistics show the number of cruise ship illness outbreaks in recent years. You can compare the number of reports (CDC and news media sources) and the total number of infected (passengers and crew).

In 2014, Time Magazine published the article "The 13 Worst Norovirus Outbreaks on Cruise Ships". In it, the overall winner was Princess Cruises with 5 epidemic illness outbreaks:

• Coral Princess (February 2009, infected 271)
• Crown Princess (January 2010, infected 396)
• Crown Princess (February 2012, infected 363)
• Sun Princess (July 2012, infected 216)
• Ruby Princess (March 2013, infected 276)

Norovirus outbreaks 2023 reports

Norovirus outbreaks 2022 reports, norovirus outbreaks 2020 reports, outbreaks 2019 reports.

In the following table, you can see all 2019-reported Norovirus outbreaks on cruise ships. The listed statistical data is based on CDC or news media reports. It shows the number of sick passengers and crew (with the respective percentage to all), along with the corresponding CDC report pages (if available) as outgoing links.

Note: When the itinerary doesn't include US cruise ports, the ship is not required to report to CDC, thus no official illness report would be issued.

With nearly 12 million cruisers departing from USA and Canada ports in 2013, the Norovirus infection rate is ~0,01% of all passengers.
• It should be noted, that in the past years on many CDC inspections was concluded the Noro virus illness source was off the ship.

In 2012, the number of reported illness outbreaks on cruise ships was 34. The total number of infected was 5542 (of those 5079 passengers and 463 crew).

Norovirus on cruise ships

All important things you should know about the "cruise virus".

Why do Norovirus incidents happen on cruise ships? There are more than 21 million US cases reported annually, of which 1 mill related to kids. Outbreaks happen mostly during winter months and mainly in more crowded places with close quarters. Among those are schools, hospitals, nursing homes, dormitories, prisons, big resorts, bigger passenger ships (including cruise ferries ). Norovirus is often branded as "cruise ship virus" simply because on ships health officials are required to report every gastrointestinal illness incident. 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.

What is Norovirus infection? 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.

The virus is named after an outbreak in Norwalk (OH, USA). 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. This virus also mutates (changing its strains). As to its efficiency - a mere 20 particles are enough to get you.

What causes Norovirus on cruise vessels is mainly contaminated food/water. When it comes to ships, it spreads mostly through physical contact with sick people or handling contaminated objects. This includes sharing food/utensils and poor hygiene (not washing hands after bathroom use). The virus also spreads fecally, so you can catch it into the onboard laundry, or while changing diapers, etc. However, many passengers likely can blame a sick crewmember for the virus. According to a survey based on 170 inspection records on ships that docked in Florida ports in 2012, on 59 cruises violations of the required illness reporting laws were reported. A total of 130 crew had gotten sick on those voyages and didn't report their illness in the required time period.

The symptoms are nausea, vomiting, diarrhea, indigestion, abdominal cramps. Also possible are mild fever and headache. It takes 1-2 days for the symptoms to appear. The illness lasts 1 to 4 days, but some people (especially elderly) may be contagious for up to 2 weeks after recovery.

What is the treatment? What to do if you got it? Obviously, the first thing is to go to the ship's infirmary (medical center) and contact the doctor. You should drink plenty of water as dehydration is a side-effect of the illness. There is no real treatment for Norovirus - you just wait it out. 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). The new vaccine generates a good immune response.

How to avoid Norovirus on cruise ships?

• Wash your hands often (hot water and soap), especially before/after eating and after using the bathroom
• Limit physical contacts as much as possible, pack some extra soap, a personal disinfectant (Lysol, Pepto-Bismol), oral rehydration sachets and treatments for diarrhea
• Avoid eating uncooked food (including salads and sandwiches) and food that cannot be washed (unless it can be peeled or shelled), drink only bottled liquids (preferably without ice), don't share drinks/utensils.
• Drink lots of water.
• Compensation for cruise illness. By contract, cruise lines are not required to compensate passengers who fall ill on cruises. However, they will compensate you if the itinerary was altered/canceled due to an illness outbreak. The deal may include up to 50% refund, up to 50% FCC (future cruise booking discount) or an option to cancel for a full refund plus reimbursement of airline change fees. If you have travel insurance, it covers cancellation due to illness. If you've been infected on the ship, it could also cover medical expenses and to compensate you for all days you're not on the ship before the cruise end.

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.

• It is critical that excellent standards of personal hygiene are maintained by all on board, as well as avoiding touching surfaces, such as handrails, door handles, elevator buttons, walls.
• Report any observed evidence of vomiting or diarrhea that you may encounter on the ship.
• Ensure that you minimize direct contact with others during this time, such as handshakes, etc.
• Avoid touching your mouth.
• Wash your hands frequently and thoroughly with soap for at least 20 sec and rinse them well under running water. Ensure that you follow this procedure every time you use the WC, after coughing or sneezing, and before eating, drinking or smoking.
• Attempt to always use your own cabin toilet facilities.
• In addition to hand washing, also use the alcohol hand gels provided where available, and in particular before eating in the self-serve buffet restaurant and outdoor food outlets.
• Should you experience any symptoms of vomiting or diarrhea, return to your cabin and immediately report to the Medical Center or Front Office (Reception, if the infirmary is busy) by dialling 999.

Cruise ship virus procedures

What do they do about it? What actions do lines/operators/CDC actually take in response to a Norovirus cruise outbreak?

An "illness outbreak" is considered when 3% or more of all passengers report symptoms to the ship's med staff. In such cases, the CDC requires cruise lines to file a medical report.

The hotel staff is required to implement special cleaning and disinfection procedures for sanitizing the whole ship. To do that, they use stronger solvents, like Microbac, chlorine bleach, hydrogen peroxide. The Lido Deck's bistro/buffet service switches to manned stations. Often, salt-pepper shakers are taken off the tables. The crew starts offering precautionary tips. Sick passengers and crew are quarantined in their rooms, typically for at least 2 days. When Norovirus outbreaks can't be contained, cruise lines might also pull the ship out of service for a few days for sanitizing.

The CDC's "Vessel Sanitation Program" is for monitoring illness outbreaks on passenger ships carrying 100 or more guests on sailings from 3 to 21 days in length. The ship's medical staff is required by the CDC to maintain illness counts for each itinerary involving a stop at a US cruise port and to give CDC the number of all passengers/crew, plus the number of reported diarrhea cases during that voyage. This is done 24 hrs prior to arrival at any US port of call from a foreign port. And they file such reports even if the "illness number" is zero. This protocol only confirms that the CDC knows everything about it.

Other possible actions and results are red level ("Code Red") cleaning. The boarding/embarkation of new passengers is often delayed to permit more extensive disinfection of public areas and the cabins. Usually, a pre-embarkation health advisory is distributed to all boarding passengers. Additional med staff is sent to the ship in port to assist the disembarkation of infected passengers. Another possibility is the cruise ship to cancel all the itinerary's foreign ports of call and to return to its US home-port before the end of the voyage.

Some cruise lines offer hand-sanitizer dispensers near the ship's restaurants, Lido/pool deck areas and other more crowded public spaces in their effort to keep a lid on sickness outbreaks.

In February 2020, the shipowner cruise company Lindblad Expeditions announced the "Premium Purity" program with a shipwide cleaning system based on ACT CleanCoat technology. The program was rolled out fleetwide after a year trial. The innovative ship cleaning process is based on photocatalytic antibacterial spray that when activated by light kills viruses, bacteria, airborne microbes, mould. The disinfecting product and technology were developed by the Danish company ACT Global AS ( Copenhagen ). The spray is chemical-free, odourless, transparent and can be applied to all surfaces.

Zika virus on cruise ships

Zika virus (aka ZIKV) is a Flavivirus - from the genus of the viruses named West Nile, dengue, tick-borne encephalitis, yellow fever. These plus several other viruses may cause encephalitis (acute brain inflammation). In humans, Zika virus causes the Zika fever which is known to occur only within some equatorial regions. In 2014, Zika spread across the Pacific Ocean to French Polynesia, and soon to Easter Island. In 2015, Zika virus reached Central America, the Caribbean, and South America. In South America were recorded several pandemic outbreaks.

The most severe outbreaks were reported in Brazil, with an alarming surge in newborns with microcephaly. If the mother is infected, the virus may cause microcephaly in newborns. This is a neurodevelopmental disorder - babies are born with an underdeveloped head.

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.

In January 2016, the CDC issued travel guidance on affected countries and suggested using enhanced precautions and even postponing travel. Guidelines (specifically for pregnant women) were issued as well. Similar travel warnings were issued by other health agencies and governments. The CDC list of potentially dangerous for travel countries included (alphabetically) Barbados, Bolivia, Brazil, Cape Verde, Colombia, Ecuador, French Guiana, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Martinique, Mexico, Panama, Puerto Rico, Paraguay, Salvador, Samoa, St Maarten, Suriname, Venezuela.

Cruise lines should warn their pregnant passengers of the virus. Cruise ships publish daily health and safety instructions to their passengers on how to avoid mosquito bites. Zika symptoms are fever, skin rash, pain in joints, conjunctivitis (pink eye). It typically lasts from a few days to a week. For now, the illness cannot be prevented by drugs or vaccines.

"Cruise ship virus" politics

Virus outbreaks on cruise ships are actually not that uncommon. 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. In confined spaces with frequent passenger turnover (like big capacity cruise ships), it is easy for diseases to spread - whether food- or air-borne, or otherwise. However, there's a tendency to cover up the severity of this issue.

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. And there is no surprise in that since the "cruise illness" news are nothing but bad publicity for the companies - which is bad for a prosperous multi-billion dollar sea travel vacation business. All major cruise line companies will do their best to keep quiet about virus outbreaks on their ships. There are passenger testimonials about quarantined ships and how badly guests have been treated by the line. Virus outbreak news speaks of a lack of proper hygiene control, badly trained staff, bad ship management. The whole responsibility goes to the shipowner (cruise line company) and its management.

Major (in some cases epidemic) illness outbreaks are among the "biggies" that can bring down the brand's reputation on the market. Cruise illness issues often result in lower booking rates and cheaper prices - which is bad for the business.

So it comes as no surprise that when CDC reports an illness outbreak on some vessel, big media sources do not immediately (or ever) respond to the news. You may hear about it on your local radio station, or on your local cable operator, but not necessarily on ABC, CNN, and often not even on Yahoo and MSN news online. It's not about the passengers' health (never been) - it's about the big money that rules our world.

So keep your hands clean, keep your mind clear, always hope for the best. Bad, if meant to happen, will happen anyway, and nothing can change it.

Seasickness on cruise ships

Seasickness is physical disorientation as a result of conflicting signals received by the brain from different body senses. Our inner ear senses the ship's irregular motion, which our eyes can't see because the floor and walls are stable. Depending on individual balance, our ability to adjust to motions varies, so not everyone experiences seasickness.

Seasickness is one of the most common "cruise illnesses". Passengers sensitive to nausea or motion sickness should consult their doctors for medical recommendations prior to departure. Drugs (like Dramamine) are effective against seasickness. At the cruise ship's Infirmary, and also at Reception Desk is provided (free of charge) Meclizine. Know that the bigger the vessel the more stable it is. Also, motion in midship-located areas (including staterooms) is highly reduced in comparison to forward and aft areas.

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. The harder the symptoms, the longer the recovery.

If seasickness symptoms are accompanied by diarrhea or fever, passengers should immediately seek medical treatment for Norovirus and avoid spreading the illness to others.

How to prevent seasickness on cruise ships (tips)

Passengers prone to motion sickness are more likely to suffer seasickness. The following prevention tips can minimize discomfort, so before the cruise:

• choose more sheltered routes (clam waters). Open sea and ocean waters are rough and have larger swells, thus river cruises are among your best choices.
• Choose a large liner as larger vessels are more stable and motions are minimized.
• Book centralized/midship stateroom and/or middle deck cabin, where motions are less noticeable.
• Get a good sleep before the voyage - an energetic, well-rested body adjusts easier to new conditions.

During the cruise tips to divert seasickness symptoms include:

• Get involved in onboard activities - this will occupy your mind while the inner ear adjusts to equilibrium changes.
• Avoid napping or lying down - when the body is horizontal, the ship's motion is more pronounced.
• Avoid eating unknown foods - you don't know how your stomach may react to new food/ingredients. Avoid alcohol and acidic-fatty-spicy foods. Stay well-hydrated by drinking plenty of water.
• Walk around to adjust the body's equilibrium to the ship's motion. When on open decks, focus on the horizon to give your eyes and body similar inputs about any tilting or other motion. Depending on the symptoms' severity, it may take several hours.
• Often get fresh air, take deep breaths, keep your lungs clear.
• Some herbal remedies (in tablets or teas) also can ease the symptoms, including ginger and peppermint. Their efficacy varies by person, and are best used together with other prevention methods.

Search for medical assistance - consult the ship's physician if no actions provide relief.

Cruise ship hospital (medical care)

Cruise vessels are not "hospital ships".

Hospital ships are designated as floating medical facilities (hospitals).

Most hospital ships are navy vessels (operated by military forces) which are specifically built for use in war zones.

Attacking a hospital ship is considered a war crime, but enemy forces have the right to board them for inspections.

As of 2018, hospital ships have Brazil (6), China (5), Russia (6), USA (2), Spain (2), and India-Indonesia-Peru-Vietnam (x1).

The navies of USA, UK, Australia, China, France, Italy, Spain, Argentina, and Japan have some classes of military ships fitted with onboard hospitals.

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.

Shipboard hospitals as facilities and equipment vary by cruise line and vessel. Clinic's size usually depends on the ship's capacity (passengers plus crew). Generally, bigger and newer ships offer larger and better-equipped medical facilities and are served by bigger infirmary staff.

The ship's medical personnel are independent contractors. This is for limiting the cruise company's liability. There are no internationally specified regulations governing ship infirmaries and medical staffing. Each company has its own standards provided for its passengers' healthcare.

For finding the Infirmary you can use the ship deck plans . On most vessels, the medical facilities are located midship on a lower deck (for easier access and better stability) and usually among other crew facilities. Every passenger stateroom has the Infirmary's number - posted or by the cabin's phone.

Basic medical care on cruise ships

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.

Infirmary's equipment and med supplies provide only emergency response and basic treatments in order to stabilize the passenger until transferred ashore.

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.

Both emergency and basic care are available on the ship 24 hours a day. All treatments are paid. Outside regular opening hours fees are higher.

Like inland hospitals, medical treatments at sea are pricey. 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.

Shipboard medical service fees vary and are usually set by medical practitioners. General consultations incur costs similar to home visits. Prescription medications or other treatments cost extra. In most cruise ship hospitals, some supplies and medications are provided to passengers and crew for free - like aspirin, seasickness pills, small bandages.

Mercy Ships

"Mercy Ships" is a charity accredited by Better Business Bureau. It operates hospital ships since 1978 and also has currently the world's largest hospital ship (excluding navy vessels) - MV Africa Mercy.

The organization provides free humanitarian aid worldwide, including health care, community development, and health education projects, mental health, agriculture, and water development programs in mainly developing countries in Africa, Caribbean, South America, Oceania.

The organization's headquarters are in Garden Valley (Texas USA), with another 16 offices worldwide - in UK, Spain, Canada, Germany, France, Denmark, Switzerland, Belgium, Holland, Sweden, Norway, South Africa, Australia, New Zealand, South Korea.

Financial support and supplies are mainly through donations from medical companies (medications, supplies, equipment), corporations (fuel, food, building supplies), governments (port fees, drydock costs), general public and also by the crew (all volunteers on a rotational basis). The crew serves with short-term (2 weeks to 2 years) and long-term (min 2 years) contracts. Volunteer crew members occupy both medical (surgeons, dentists, nurses) and general jobs (deckhands, seamen, engineers, machinists, electricians, teachers, cooks, welders, plumbers, agriculturalists.

The crew on Mercy Ships pay all costs associated with their service - fees, travel expenses, passports, insurance, personal expenses.

As 95 of the world's top 100 largest megapolises are port cities, "hospital ships" could provide healthcare very quickly and more efficiently to large numbers of people.

MV Africa Mercy

MV Africa Mercy is a converted former rail ferry (1980-built as "Dronning Ingrid") drydock-refitted in 2007 at Cammell Laird shipyard (Hebburn, England).

The ship project started in March 1999 with the vessel's acquisition through a donation from Balcraig Foundation (UK), which purchased the boat for US$6,5 million.

Ferry's train deck was reconstructed and converted into a hospital. Project's total cost was over USD 62 million.

Vessel details include:

• Volume/GT tonnage 16572 tons
• LOA length 152 m (499 ft )
• Width 23,7 m (78 ft)
• Draft 6 m (20 ft)
• Powerplant 4x BW main engines plus diesel generators
• Propulsion two shafts with controllable pitch propellers
• Speed 19 Kn/35 kph/22 mph
• Passenger capacity 484
• Crew capacity 450
• Fleet of 28 vehicles (used in land-based operations)
• Annual drydock maintenance and refurbishment are done in Durban (South Africa).

As for facilities and amenities, the hospital ship has 5 operating rooms, Intensive Care Unit, an ophthalmic unit, CT scanner, X-Ray, labs, recovery ward (82 beds), a daycare center, a school (for all ages), library, launderette, convenience store, restaurant, gymnasium, shops, Starbucks Cafe (donated), satellite communications.

Africa Mercy has a total of 126 staterooms for the staff/crew. They are located on upper decks and include cabins for families, couples and single cabins.

Land-based operations ("Field Service") include mobile clinics providing screening for potential surgery patients, healthcare, dental care, also mental health programs, infrastructure projects.

Norovirus outbreaks on cruise ships surge to decade-high levels: How to avoid the stomach bug

In 2023, a decade-high number of cruise ships have reported an unwelcome passenger on board: norovirus.

Outbreaks of the stomach bug have surged on cruise ships this year, reaching the highest levels seen in 10 years. Since January 2023, there have been 13 confirmed norovirus outbreaks on cruise ships under U.S. jurisdiction — that's more outbreaks in six months than there have been during any full year since 2012, according to data from the U.S. Centers for Disease Control and Prevention .

After a lull during the COVID-19 pandemic, cases of the highly contagious virus that causes diarrhea and vomiting, aka stomach flu, spiked this winter and spring on land. 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 outbreaks on cruise ships

Most recently, a norovirus outbreak in June on the Viking Neptune sickened 110 passengers (over 13% of the ship's guests) and nine crew members with vomiting, diarrhea and abdominal cramps, according to the CDC . The CDC has tracked outbreaks of gastrointestinal illness on cruise ships through its Vessel Sanitation Program (VSP) since 1994.

Several weeks prior, a Celebrity Summit cruise ship reported an outbreak of norovirus that sickened more than 150 passengers and 25 crew members, per the CDC . It was the third norovirus outbreak on a Celebrity Cruises vessel this year. Another popular cruise line, Royal Caribbean International, has reported four outbreaks since January.

Cruise ships are required to report cases of gastrointestinal illness to the CDC before arriving at any U.S. port, and the CDC will notify the public about outbreaks if they meet certain criteria, including: the ship is carrying 100 or more passengers, the voyage is three to 21 days long, and 3% or more of passengers or crew report symptoms, per the CDC .

The number of outbreaks in the first six months of 2023 is higher than the yearly total during every year since 2012, when there were 16 outbreaks on cruise ships reported to the CDC.

Norovirus can spread year-round, but it tends to have a wintertime seasonality and peak during the colder months. Outbreaks are most common between November and April, TODAY.com previously reported.

"It's a virus we typically see all throughout spring, so it’s not unusual to be see cases in April and May, (and) we are continuing to see many cases now," Dr. Luis Ostrosky, an infectious disease specialist at UTHealth Houston and Memorial Hermann in Houston, tells TODAY.com.

However, as travel surges this summer, travel-related illnesses are expected to surge, as well. “I think our travel frenzy after COVID is partially fueling this continued spread (of norovirus),” says Ostrosky.

What should people know about norovirus and how to avoid getting sick on cruise ships this summer?

Norovirus symptoms and treatment

The most common symptoms of norovirus are vomiting, nausea, diarrhea and abdominal pain, Dr. Albert Ko, infectious disease physician and professor of public health, epidemiology and medicine at Yale School of Public Health, tells TODAY.com.

Less commonly, norovirus may cause a headache, muscle aches, or a low-grade fever — symptoms usually develop within one to two days after exposure to the virus,  per the CDC .

In the vast majority of people, norovirus symptoms will last several days and resolve on their own.

There’s no specific treatment or antiviral for norovirus, according to Ostrosky, but most cases can be managed at home with supportive care like hydration and rest. Sick people should also isolate until their symptoms resolve, the experts emphasize.

Some people are at higher risk of developing severe norovirus symptoms — these include infants, the elderly, and people with compromised immune systems, Ostrosky noted.

How does norovirus spread?

Norovirus is highly contagious and can spread directly through sick people and contaminated surfaces, food, or drinks.

Transmission often occurs when tiny virus particles in feces or vomit from an infected person end up in another person's mouth through direct contact or by touching contaminated surfaces and putting unwashed hands in the mouth or nose, TODAY .com previously reported .

Norovirus can also get into food before, during or after preparation, and it's the top germ causing foodborne illness in the U.S., per the CDC . Virus particles can contaminate drinking water that isn't treated properly or pools when people poop in the water.

It only takes a small number of virus particles for norovirus to spread, which is why norovirus causes so many explosive outbreaks, Ko 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.

Most people are infectious from symptom onset until about two or three days after recovering, but some people can remain contagious for weeks, Ko notes. People can get infected with norovirus multiple times in their lifetime.

Is norovirus common on cruise ships?

Certain environments are more conducive to the virus spreading. According to the CDC , the most common settings for norovirus outbreaks are health care facilities, restaurants or catered events, schools, day cares and, of course, cruise ships.

Cruise ships are often associated with norovirus because of the enclosed spaces, close living quarters, communal dining and high turnover of passengers, experts note. That said, outbreaks of acute gastrointestinal illnesses are relatively infrequent on cruise ships compared to settings on land, the CDC notes .

How to avoid norovirus on a cruise

Hand hygiene is key to prevent the spread of the highly contagious virus — but the way you clean your hands matters, experts note. It has to be with soap and water, because alcohol-based hand sanitizers are not effective against norovirus.

“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.

It's important to wash your hands with soap and clean water frequently, but especially after using the bathroom or changing diapers, before eating and before touching your face.

Surfaces or objects that are contaminated with norovirus can be cleaned with a high-level disinfectant like bleach, per Ostrosky.

On cruise ships, avoid sick people if you can. Passengers who experience norovirus symptoms like vomiting and diarrhea should notify staff and follow recommended precautions, per the CDC .

Norovirus outbreaks surging on cruise ships this year

By Emily Mae Czachor

July 12, 2023 / 10:33 AM EDT / CBS News

Norovirus outbreaks spiked on cruise ships this year, with data showing more outbreaks happened between January and June than over the course of any other full calendar year in the last decade. Thirteen norovirus outbreaks have been reported on cruises so far in 2023, according to the  U.S. Centers for Disease Control and Prevention , which keeps a record of annual case counts dating back to 1994. 

The most recent outbreak hit passengers and crew members on board a Viking Cruises trip from Iceland that docked in New York on June 20. More than 13% of passengers on the Viking Neptune — 110 of 838 in total — reported being ill while onboard, according to the CDC. Nine crew members reported being ill as well. Health officials at the CDC determined that norovirus caused the outbreak after Viking Cruises collected and sent specimens to the agency's laboratory for testing.

Those cases in June came after multiple norovirus outbreaks in previous months that affected a range of cruise lines. 

In May, two outbreaks were reported on voyages led by Celebrity Cruises and Holland America. In March, Celebrity Cruises reported two norovirus outbreaks, as did Royal Caribbean International and Princess Cruises. Princess Cruises reported its first outbreak of the year in February, and Royal Caribbean International reported two the previous month. P&O Cruises also reported an outbreak on its Arcadia cruise ship this year.

The CDC's tally of norovirus outbreaks so far confirmed on cruise ships in 2023 is already higher than any annual outbreak tallies since 2012, when the health agency recorded 16 outbreaks. 

Symptoms of norovirus

Norovirus is a highly contagious virus that causes acute gastroenteritis, which is inflammation in the stomach or intestines, according to the CDC . Health officials say norovirus is the most common cause of vomiting and diarrhea as well as the most common type of foodborne illness .

Norovirus is often referred to as a "stomach bug" or "stomach flu" (although it is not a form of flu). It causes a variety of symptoms including nausea, vomiting, diarrhea and stomach pain. People infected with the virus may also have headaches, fevers and body aches, and are at risk of dehydration.

The virus spreads easily and is typically contracted when someone accidentally ingests tiny particles of vomit or feces from someone who is infected with it. The CDC writes that people who are infected "can shed billions of norovirus particles that you can't see without a microscope," and exposure to just a few norovirus particles can make someone sick. 

Symptoms typically emerge within 12 to 48 hours of being exposed. Most people get better after a few days, but severe cases may require hospitalization.

Studies have shown that norovirus can continue to spread for two weeks or more after an infected person stops having symptoms of the illness, according to the CDC.

Cruise lines battle norovirus outbreaks, affecting crews, hundreds of passengers. Here's what to know

In all, about 1,700 people reported being sick with norovirus aboard a cruise ship between January and June of this year. 

By Monica Galarza and Marissa Bagg • Published July 13, 2023 • Updated on July 13, 2023 at 6:49 pm

The Centers for Disease Control and Prevention is reporting the highest number of norovirus outbreaks in over a decade and it is impacting hundreds of passengers and crew members onboard some of the most prominent cruise lines.

In the first six months ending in June, cruise lines have reported 13 separate outbreaks to the CDC. It’s the most number of reported norovirus outbreaks on cruise ships since 2012.

One local expert says it’s in part because more people are cruising. 

“The hundreds of thousands, if not millions of people that have already gone on cruises without incident. It’s a very small number and it’s there’s nothing to be concerned about,” said Steward Chiron, a cruise expert. “I would not think twice about going on a cruise. I would not think twice about going on a cruise or traveling anywhere.”

Celebrity, Royal Caribbean International, Holland America, Princess and P&O were among the Royal Caribbean and Carnival lines affected.

So if you're planning to set sail this summer, here's everything you need to know about the norovirus.

What is norovirus?

According to the CDC, norovirus is the leading cause of vomiting, diarrhea, and foodborne illness in the United States.

It's also not a one-and-done virus. You can get norovirus illness many times in your life because there are many different types of noroviruses and one type may not protect you against the others.

It is possible, however, to develop protection against specific types, but it's not known exactly how long protection lasts.

This may explain why so many people of all ages get infected during norovirus outbreaks.

According to the CDC, your likelihood of getting a norovirus infection is also determined in part by your genes.

How does norovirus spread?

Because people of all ages can get sick with norovirus, it can spread easily and quickly.

The CDC says norovirus can be spread by:

• Having direct contact with someone with norovirus, such as by caring for them, sharing food or eating utensils with them, or eating food handled by them.
• Eating food or drinking liquids that are contaminated with norovirus.
• Touching surfaces or objects contaminated with norovirus and then putting your unwashed fingers in your mouth.

You are at your most contagious when you have  symptoms  of norovirus illness, especially vomiting or during the first few days after you feel better.

But studies have shown that you can still spread norovirus for two weeks or more after you feel better.

According to Mayo Clinic , norovirus most often spreads in closed and crowded environments, such as hospitals, nursing homes, child care centers, schools and cruise ships.

But it can also spread through contaminated food, water or through sick people and contaminated surfaces.

What are the symptoms of norovirus?

According to the CDC, the most common symptoms of norovirus are diarrhea, vomiting, nausea and stomach pain.

You may, however, experience fevers, headaches, and body aches.

Symptoms usually last one to three days and most people recover, according to the Mayo Clinic.

How do you treat norovirus?

There is no specific medicine to treat people with norovirus illness.

If you have norovirus illness, the CDC recommends you drink plenty of liquids to replace fluid lost from vomiting and diarrhea and help prevent dehydration.

Sports drinks and other drinks without caffeine or alcohol can help with mild dehydration, but these drinks may not replace important nutrients and minerals.

It is important to note that antibiotic drugs will not help treat norovirus infections because they fight bacteria, not viruses.

When was the most recent norovirus outbreak on a cruise ship?

The CDC's latest report of a norovirus outbreak happened on Viking Neptune, a cruise ship owned by Switzerland-based Viking Cruises, during a voyage from June 6 to June 20.

According to the CDC, 110 of 838 passengers and nine of the 455 crew members reported feeling ill during the trip.

The following ships saw outbreaks so far in 2023: Celebrity Summit, Nieuw Amsterdam, Grand Princess, Emerald Princess, Enchantment of the Seas, Celebrity Equinox, Celebrity Constellation, Ruby Princess, Viking Neptune, Jewel of the Seas, Brilliance of the Seas, Arcadia.

What can I do to prevent contracting norovirus?

The key to preventing norovirus , and most other illnesses is simply washing your hands well.

Norovirus is very contagious, but you can take steps to stop it from spreading.

Wash your hands often with soap and water for at least 20 seconds, especially:

• After using the toilet or changing diapers.
• Before eating, preparing, or handling food.
• Before giving yourself or someone else medicine.

It is important to continue washing your hands often even after you feel better.

Chiron says cruise lines try to keep ships clean and limit some interactions. 

“What they do is they reduce the person-to-person interactions. So when you go to the buffet for example for breakfast or lunch. Instead of serving yourself a gloved crew member will do it for you,” said Chiron.

When on board, if you see someone with norovirus symptoms, you’re urged to leave the area and alert a crew member. 

Norovirus can be found in your vomit or feces (poop) even before you start feeling sick. The virus can also stay in your poop for two weeks or more after you feel better and you can still spread norovirus during that time.

Hand sanitizer does not work well against norovirus. You can use hand sanitizers in addition to hand washing, but hand sanitizer is not a substitute for handwashing.

More than 175 people fall ill in Celebrity Cruises norovirus outbreak

More than 175 people got sick with norovirus during a recent Celebrity Cruises’ sailing, the Centers for Disease Control and Prevention said.

The agency said 152 of the Celebrity Summit ship’s 2,144 passengers, as well as 25 crew members, reported being ill during its May 15 voyage, according to its website . Their main symptoms were diarrhea, vomiting, abdominal cramps and headache.

"The health and safety of our guests, crew and communities we visit are our top priority," a Celebrity spokesperson said in an emailed statement. "To maintain the highest levels of health onboard our ships, we implement rigorous safety and cleaning procedures, many far exceeding public health guidelines. Combined, these efforts allow us to maintain some of the lowest levels of community spread."

The cruise line and ship’s crew implemented heightened “cleaning and disinfection procedures according to the ship’s outbreak prevention and response plan,” notified guests and encouraged practicing good hand hygiene and reporting illness, according to the agency. They also provided reports of gastrointestinal illness cases to the CDC’s Vessel Sanitation Program twice a day during the outbreak investigation, among other steps.

The incident marks the third norovirus outbreak on Celebrity ships the CDC has posted this year. The line previously saw outbreaks on its Celebrity Equinox and Celebrity Constellation vessels in March. On Celebrity Equinox, 136 passengers and crew reported being ill, while 96 did so on Celebrity Constellation.

Gastrointestinal illness at sea plummeted during the COVID-19 pandemic, but cases have ticked up again as the industry has rebounded.

While norovirus is frequently associated with cruise ships, Ben Lopman, a professor of epidemiology at Emory University’s Rollins School of Public Health, told USA TODAY in February that those represent a "tiny minority of norovirus outbreaks.” The vast majority take place in health care settings like nursing homes, he said.

Matador Original Series

2024 is already shaping up to be the year of cruise ship norovirus cases.

A nother month, another norovirus outbreak on a cruise ship. On March 12, reports started to surface that 98 passengers and 12 crew members tested positive for the virus on a Holland America Line cruise that left San Diego on February 17, with planned stops in Hawai’i and French Polynesia. It marks the third instance in the first three months of 2024 to be listed on the Centers for Disease Control and Prevention (CDC) tracker .

The cruise industry’s norovirus year started early. The Celebrity Cruises Constellation ship left from Tampa, Florida, on January 3 with planned stops in New Orleans, Belize, and Mexico. Shortly after, 92 of 2,056 guests and eight crew members were reported ill with vomiting and diarrhea during a norovirus outbreak, according to USA Today . Then, in February, more than 150 people were confirmed with norovirus on Cunard Line’s Queen Victoria that departed from England with stops in Florida and San Francisco.

That’s not counting the Norwegian Dawn incident in late February, which was originally reported as cholera but was changed to a “stomach-related illness.” Or, in the words of a Matador editor on the ship, “plenty of cases of stomach-related illnesses. Of the frequent stomach-related illnesses on cruise ships, norovirus is the most common.”

2024 is surely starting strong after what was a breakout year for norovirus in 2023. The CDC, which is the only agency tracking norovirus outbreaks on cruise ships and only follows up on outbreaks on ships that dock in United States ports, recorded the highest disease outbreak incidence rate in 10 years in 2023. That year saw 14 outbreaks that met the public notification threshold, and 13 of those were from norovirus (the other was due to Salmonella and E. Coli).

Norovirus is neither novel nor exceptional. Tens of millions of people get it every year, and the CDC lists it as the “leading cause of vomiting and diarrhea, and foodborne illness in the United States.” It spreads easily, is hard to build immunity against because there are different types of noroviruses, and it’s unknown how long protection lasts even if someone does get antibodies for one particular strain.

It’s easy to pass — especially with raw foods, though norovirus can withstand heat up to 145 degrees Fahrenheit — and hand sanitizer is not super effective. Norovirus can quickly travel from one cook’s unwashed hands to dozens of plates in front of diners.

Diarrhea, vomiting, nausea, and stomach pain are the most common norovirus symptoms, followed by fever, headache, and body aches. It’s often accompanied by stomach or intestine inflammation, or acute gastroenteritis. Symptoms start 12-to-48 hours after exposure, and last for up to three days (though people can stay contagious for longer).

In the grand scheme of things, norovirus is not solely a cruise ship problem. Industry officials are all too eager to point out to the press that an estimated 1 percent of norovirus cases tracked by the CDC are on or from cruise ships. Schools, nursing homes, hospitals, and restaurants make up the vast majority of root sources. But it’s important to put those numbers in perspective.

The total number of cruise passengers in 2023 isn’t available as of writing, but the industry source Cruise Lines International Association (CLIA) forecasted 31.5 million people around the world went on a cruise last year. Numbers from Statista point to just under 12 million American passengers in 2022, the latest year that numbers are available. That amounts to about 3 percent of the US population. So yes, comparatively few norovirus cases are tied to cruises, but that 1 percent of norovirus cases stemming from cruise ships has new meaning when considering the comparatively miniscule number of people who are cruising compared to the number of people going to restaurants, healthcare facilities, and schools.

There’s simply no getting around the fact that the likelihood of getting norovirus is statistically higher on a cruise ship than it is when you go to any random restaurant, classroom, or hospital in the country.

It’s hard to blame cruise ships. People get sick when traveling, and that’s a tale as old as time. Whose responsibility, of course, is harder to pin down, and CLIA makes it pretty clear where the industry stands: “All of the efforts made by cruise ship crews cannot replace the responsibility that rests with each and every individual. Passengers and crew alike must also be committed to keeping themselves, their family and their fellow travelers healthy.”

There’s only so much that one can do. A 2005 study in the journal Emerging Infectious Diseases studies norovirus transmission on a cruise ship that had back-to-back-to-back itineraries. It found that after passengers on the first cruise came down with the illness, the new passengers on the second and third cruises were infected with the same strain of the virus as well as new strains (as determined by genetic sequencing). This is despite the fact that the ship was sanitized before the second boarding. Three more cruises on the ship had higher positive cases than background levels, but stayed below the 3 percent threshold of calling it a big outbreak.

All that’s left to see is whether cruise lines can figure out a way to get ahead of the issue in a year when cruises are undeniably booming with at least 35 around-the-world cruises to choose from.

Nearly 70 Celebrity Cruises guests sick in norovirus outbreak

Nearly 70 Celebrity Cruises passengers got sick in a norovirus outbreak during a recent cruise.

The Centers for Disease Control and Prevention said 68 of Celebrity Summit’s 2,264 guests reported being ill during a cruise that ended on Friday, along with five crew members. Their main symptoms were diarrhea and vomiting.

The ship is currently sailing week-long Alaska voyages between Vancouver and Seward, according to CruiseMapper . In response to the outbreak, the cruise line isolated sick guests and crew and collected samples for testing, among other steps, the health agency said.

There were an isolated number of cases on board and the impacted guests are no longer on the ship, according to Nathaniel Derrenbacher, a spokesperson for Celebrity’s parent company Royal Caribbean Group. Summit was also sanitized.

The news follows another norovirus outbreak on Celebrity Constellation in January that left nearly 100 guests sick. The CDC has logged seven outbreaks of gastrointestinal illness on cruises that met its threshold for public notification so far this year. Norovirus was listed as the causative agent in all but one.

Cruise ship medical facilities: What happens if you get sick or injured (or bitten by a monkey)

The illness is frequently associated with cruise ships, but those outbreaks account for just 1% of all outbreaks reported, according to the CDC. Dr. Sarah E. Hochman, a hospital epidemiologist and the section chief of infectious diseases at NYU Langone Health’s Tisch Hospital, told USA TODAY in April that those happen in communities on land, too.

“There's not something special or unique about cruise ships,” she said at the time. “It's really any type of congregate setting, but it's also happening out in the community on a much smaller scale among households and household contacts. It just doesn't come to the attention of public health as much as it does for larger congregate settings.”

Norovirus Outbreaks on Cruise Ships: How to Avoid Getting Sick on Vacation

• There have been 13 norovirus outbreaks on cruise ships in 2023.
• Experts note that the highly congested environment, as well as the fact that people have not been exposed to as many illnesses due to the COVID-19 pandemic, are likely the reason for the increased norovirus numbers.
• Experts recommend maintaining proper hygiene habits and contacting the ship’s medical facility as soon as you don’t feel well in order to avoid spreading illnesses while at sea.

Multiple cruise lines are experiencing norovirus outbreaks.

There have currently been 13 norovirus outbreaks on cruise ships in 2023. The most recent outbreak occurred on a Viking Cruises ship, which traveled from Iceland and docked in New York City. About 13% of its passengers and several crew members became ill with the virus while on board.

With more than 31 million passengers worldwide expected to set sail this year, experts told Health that these highly-congested environments—along with the fact that people have not been exposed to a normal amount of illnesses due to the pandemic—could be the reasons for the increased numbers.

“Loosening of restrictions after the COVID-19 pandemic makes us more susceptible to picking up viruses after several years in seclusion,” Sanjiv Shah, MD, MPH , an infectious disease specialist and chief medical officer for MetroPlusHealth, New York City’s public health insurance program, told Health.

“Children who have been able to avoid the virus during the pandemic are now being exposed to viruses that tend to peak during the school year,” he said. “While norovirus is higher this year, the numbers are not a big outlier compared to pre-pandemic levels.”

What Is Norovirus?

Norovirus is the most common cause of gastroenteritis and foodborne illness . Though people often call it the “ stomach flu ,” it has nothing to do with flu, Brian Labus, PhD, MPH, REHS , an expert in infectious diseases, told Health .

“You have to swallow the virus to get sick,” Labus, an assistant professor in the Department of Epidemiology and Biostatistics at the UNLV School of Public Health, said. “That can be through consuming contaminated food or touching a contaminated surface and then touching your mouth or not washing your hands before you eat.”

Norovirus, which causes inflammation of the stomach or intestines, typically causes diarrhea , vomiting, nausea, and stomach pain Bernadette Boden-Albala, DrPH, MPH , director and founding dean of the Program in Public Health at the University of California Irvine told Health . Other symptoms can include fever, headache, and body aches.

Typically, norovirus lasts for one to three days, though you can spread the illness for a few days after.

“Infected people spread the virus widely and make it difficult for public health officials to contain the virus,” Boden-Albala said.

Why the Number of Norovirus Outbreaks Increased

The exact cause for the increase in the number of norovirus cases is not clear, but the increasing demand for cruises could be one explanation for the rise in reported cases, said Labus.

During COVID, the options for cruises were limited, but now that restrictions have been lifted , more people are deciding to take that cruise they had been putting off.

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.

It also is possible the numbers for norovirus on cruise ships appear more alarming than they truly are.

On cruise ships, health officials are legally required to track any illnesses that occur, while this same reporting is not required on land. For this reason, the Centers for Disease Control and Prevention note that outbreaks are reported more frequently on sea than on land.

“The risk of getting norovirus each year is about 1 in 15 [but] a cruise passenger has about a 1 in 5,500 risk of getting norovirus,” Sally Andrews, vice president of strategic communications and public affairs for the Cruise Lines International Association told Health .

Environments Where Norovirus Spreads Quickly

According to Shah, norovirus spreads rapidly anywhere there are large groups of people, like school classrooms, family gatherings, and weddings.

Cruise ships in particular have many of the conditions that make people susceptible to norovirus—close quarters, enclosed spaces, communal dining, and high turnover of passengers.

“The virus is often associated with cruise travel simply because health officials are required to track illnesses on ships,” Shah said. “The CDC estimates only about 1% of annual U.S. norovirus cases happen on cruise ships. Rates are much higher in schools, nursing homes, hospitals, and restaurants, which collectively account for about 91% of cases.”

Minji Kang, MD, an assistant professor and infectious disease specialist in the Department of Internal Medicine at UT Southwestern Medical Center added that norovirus can also be brought onboard by contaminated food or water, or passengers who were infected while ashore.

Yes, Cruise Ships Have Strategies to Prevent Outbreaks

Because norovirus outbreaks can flare up in the close quarters of a ship, the cruise industry has had norovirus prevention programs in place for nearly 20 years, Labus said. “They have the right chemicals needed to control it and the plans and training for how to use them appropriately.”

Cruise ships also have plans for how to deal with ill guests to ensure that they are not infecting other passengers, he said. “It’s important to let the ship’s medical staff know if you are sick so that they can protect the rest of the passengers.”

According to the American College of Emergency Physicians (ACEP), every cruise ship must have a place to isolate any passengers who have a contagious disease. This step helps them minimize the risk of spreading the disease to others.

What’s more, the CDC has established a rigorous Vessel Sanitation Program (VSP) to help prevent the overall spread of illnesses on cruise ships. Not only do they inspect a cruise ship’s medical center, but they also monitor their portable water systems, dining rooms, housekeeping procedures, heating, ventilation, air conditioning (HVAC) systems, and more.

If a cruise ship does not do well on its inspection—or gets an 85% or lower—it cannot set sail until it corrects the issues.

Staying Healthy While on a Cruise

While there have been 13 outbreaks of norovirus on cruise ships this year, Labus explained that not every cruise passenger is going to be exposed to the virus. Still, taking certain steps to prevent the likelihood of getting sick is never a bad idea.

“The most important measure to prevent the spread of norovirus is to wash your hands with soap and water for at least 20 seconds,” said Kang. “This should be done before eating and drinking, brushing one’s teeth, and after going to the bathroom, touching high-hand contact surfaces, and taking care of a sick person.”

She noted that hand sanitizers do not work well against norovirus and that they are not a substitute for handwashing.

For extra peace of mind, you can also research your cruise line prior to booking.

To see how your specific cruise line performed on its VSP inspections, you can visit the CDC website and search their portal. This site also lists any corrective actions taken to remedy any issues. You can even look for cruise lines that have scored a perfect 100.

If you do happen to get sick while on a cruise, Boden-Albala recommends that you follow CDC guidelines and report your illness to the ship’s medical facility as soon as possible. “[You also should] rest and drink plenty of water to rebuild your immunity system and prevent dehydration.”

Even though you may be tempted to conceal your illness, you would be doing a great disservice to the other passengers and the crew on the cruise by keeping it a secret.

“While staying in your cabin [for a day or two] may not make for the best vacation,” Shah said, “it’s important to take precautions to avoid infecting others.”

Norovirus outbreak on Royal Caribbean cruise ship sickens 475 passengers

The ship will be cutting its journey short.

The Royal Caribbean Oasis of the Seas cruise ship is cutting its journey short after 475 passengers and crew members have been infected with a norovirus, Royal Caribbean Cruises announced Thursday.

The cruise line initially reported on Thursday that more than 250 passengers had fallen ill.

“We think the right thing to do is to get everyone home early rather than have guests worry about their health ” the cruise line said in a statement, adding that returning early “also gives us more time to completely clean and sanitize the ship before her next sailing.”

Guest and crew members began getting sick when the ship departed the Port Canaveral in Florida on Jan. 6. The ship, originally scheduled for a seven night cruise, made its first stop in Haiti Tuesday where the ship hosted a lunch buffet on land, said Abby Perrin, a passenger on the ship told ABC News. That night, Perrin said she and her mother began experiencing symptoms associated with food poisoning, like vomiting.

The next day, the ship arrived to Jamaica, but passengers said they weren’t allowed to leave the vessel.

Thursday morning, the ship headed for its next scheduled destination in Cozumel, Mexico , but officials canceled the cruise while it was still en route. Now it is on its way back to Florida.

“It was pretty upsetting that we weren’t able to get into Jamaica at all,” Perrin said. “Then we were supposed to be in Mexico tomorrow, which we were really excited about, and it turns out we’re going back to Florida instead.”

About three percent of people aboard the ship are affected by the norovirus, according to the cruise company.

Alan Thomas is currently aboard the ship with his spouse and two friends.

“People are still getting sick,” he told ABC News. “At a cafe next to Guest Services last night, there was a kid vomiting in the trash can.”

Thomas shared a video on Twitter of crew members cleaning the ship. He told ABC News that crew members are not allowing guests to serve themselves food or drinks.

Norovirus is a contagious virus that causes vomiting and diarrhea. A person can become infected through having direct contact with another infected person, consuming contaminated food or water, or touching their nose and mouth after touching contaminated surfaces, according to the Centers for Disease Control and Prevention (CDC).

In 2017, about 220 passengers aboard a five-night Royal Caribbean cruise suffered from a gastro-intestinal illness .

All of the current Oasis of the Seas passengers will receive a full refund, Royal Caribbean Cruises said in the statement.

“Our guests sail with us to have great vacations, and we are sorry this cruise fell short,” the statement reads.

The cruise company said the ship is scheduled to return to Florida on Saturday.

We asked: Should I cancel a cruise if my ship had norovirus?

Does it matter what happens on the cruise before your cruise? We asked infectious-disease experts for answers.

Traveling has always come with complications. Our By The Way Concierge column will take your travel dilemmas to the experts to help you navigate the new normal. Want to see your question answered? Submit it here .

“What do you do if you’re a passenger on a cruise directly following a norovirus outbreak? Should you rebook?” — Washington Post travel reporter Andrea Sachs

Even though it feels as if we hear a lot about gastrointestinal illness on cruise ships, the Centers for Disease Control and Prevention says outbreaks are “relatively infrequent.” Because health officials track illness on cruises, outbreaks are found and reported quicker on ships than on land, the CDC says.

But it happens . So far this year, the CDC has reported 13 outbreaks of norovirus — more than the annual total of gastrointestinal illnesses reported on cruise ships visiting U.S. ports in each year dating back to 2017; the CDC imposed a no-sail order for much of 2020 because of the coronavirus pandemic, and U.S. cruises were required to follow pandemic-era restrictions until January 2022 , which may have also helped contain norovirus . Although outbreaks may affect more than 100 passengers, the two most recent cases represented about 13 percent and 7 percent of guests, respectively.

So how far do you need to go to evade the stomach bug on your vacation?

Let’s start with what I heard from Bernadette Boden-Albala, the director and founding dean of the Program in Public Health at the University of California at Irvine, who has extensively researched and studied norovirus and is still a fan of cruise travel. In fact, she emailed me from a cruise ship.

Her take: You don’t need to rebook if you hear there has been an outbreak on the sailing before yours. You and the cruise line are on the same page: Nobody wants you getting sick on board.

“Norovirus is a worst fear for all cruise lines,” Boden-Albala says.

She mentioned information you’ll also find on the norovirus page of the Cruise Lines International Association website: When a gastrointestinal illness plagues a cruise, the captain and crew follow deep-cleaning and sanitation practices developed with public health authorities. Additionally, Kendra Holmes, the CEO of Miray Cruises, says a ship’s crew is monitored for symptoms, and if anyone does display symptoms, they’re quarantined and treated.

Shoshana Ungerleider, a board-certified internal medicine physician and host of the “TED Health” podcast, also says that, thanks to the norovirus cleaning protocols on ships, the risk of getting an infection on the following cruise should be quite low.

Flying during summer storm season? Better have a backup plan.

“That being said, norovirus is highly contagious and can be spread from person to person,” she wrote in an email. “If any of the crew members were infected and are still in the incubation period or showing symptoms, there might be some risk of transmission.”

According to the CDC, the incubation period for norovirus — the time it takes between infection and the onset of symptoms — is between 12 and 48 hours.

So the decision to travel or not should depend on several factors, Ungerleider says, including your personal health status and risk tolerance.

For most young and healthy people, norovirus isn’t much of a health risk, says Eyal Leshem, an infectious-disease expert at Sheba Medical Center who previously worked at the CDC. With some hydration and rest, you should recover within days.

But for elderly people or those who suffer from chronic illnesses, Leshem says norovirus can cause severe disease, which may occasionally result in hospitalization and even death. He would advise such travelers to follow up to make sure the ship has followed the CDC’s guidance and recommendations for outbreaks.

Ungerleider says those high-risk travelers may want to consider rebooking their trip for the peace of mind alone.

But not all cruise ships are the same, Boden-Albala says; you can allay some of your fears by choosing ships that come with less risk. Because norovirus risks increase when you have lots of people inside close quarters, look for smaller ships that carry fewer passengers and give you lots of opportunities to spend time outdoors. (So, not a ship like this .)

On board, Boden-Albala avoids crowded situations. “I rarely use a buffet,” she says.

Most importantly, wash your hands a lot. Boden-Albala says this is the best measure you can take to protect yourself and your loved ones from the potential spread of disease. Do it the way you relearned during the pandemic: with soap and warm water for at least 20 seconds, scrubbing around and under your fingernails and between your fingers. Do it not just before eating or drinking, but also before brushing your teeth, blowing your nose, changing a diaper, et cetera.

“You must be diligent beyond your common understanding of when to wash your hands, because there are millions of norovirus particles spreading in various areas,” Boden-Albala says.

You can use hand sanitizer in addition to — but not as a substitute for — hand-washing, as Boden-Albala notes that it doesn’t do well against norovirus on its own.

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.

Norovirus Outbreaks

• Each year, there are about 2,500 reported norovirus outbreaks in the United States.
• Most norovirus outbreaks happen when infected people spread the virus to others through direct contact.
• Norovirus outbreaks have been reported in many settings. Some of the most commonly reported outbreak settings are listed below.

When and how outbreaks happen

A norovirus outbreak is defined as:‎.

Most outbreaks of norovirus illness happen when infected people spread the virus to others through direct contact. This can happen by caring for them or sharing food or eating utensils with them. Food, water, and surfaces contaminated with norovirus can also cause outbreaks.

Each year, there are about 2,500 reported norovirus outbreaks in the United States. Norovirus outbreaks occur throughout the year but are most common from November to April.

Current alerts and advisories

CDC works closely with our federal regulatory partners on norovirus outbreak investigations. The following are current food safety advisories or product recalls:

• FDA Advises Restaurants and Retailers Not to Serve or Sell and Consumers Not to Eat Certain Frozen, Raw, Half-shell Oysters from Republic of Korea Potentially Contaminated with Norovirus
• FDA Advises Restaurants and Retailers of a Recall of Certain Oysters from Westport, Connecticut Potentially Contaminated with Norovirus
• FDA Advises Restaurants and Retailers Not to Serve or Sell and Consumers Not to Eat Certain Oysters from Baja California, Mexico Potentially Contaminated with Norovirus
• FDA Advises Restaurants and Retailers Not to Serve or Sell and Consumers Not to Eat Certain Oysters from Bahia Salina in Sonora, Mexico Potentially Contaminated with Norovirus

• FDA Advises Restaurants and Retailers Not to Serve or Sell and Consumers Not to Eat Certain Raw Oysters from Dai One Food Co., Ltd, Republic of Korea Potentially Contaminated with Norovirus

Common settings of norovirus outbreaks

Healthcare facilities.

The most commonly reported setting for norovirus outbreaks in the United States and other industrialized countries is healthcare facilities. This includes long-term care facilities and hospitals. Over half of all norovirus outbreaks reported in the United States occur in long-term care facilities.

The virus can be introduced into healthcare facilities by infected patients, staff, visitors, or contaminated foods. Outbreaks in these settings can sometimes last months. Compared with healthy people, norovirus illnesses can be more severe—and occasionally even deadly—in patients in hospitals or long-term care facilities.

Restaurants and at catered events

Foods commonly involved in norovirus outbreaks:‎.

- Leafy greens (such as lettuce)

- Fresh fruits

- Shellfish (such as oysters)

Norovirus is the leading cause of outbreaks from contaminated food in the United States. About 50% of all outbreaks of food-related illness are caused by norovirus. Most of these outbreaks occur in food service settings like restaurants. Infected food workers are frequently the source of outbreaks in food-service settings, often by touching ready-to-eat foods (such as raw fruits and vegetables) with their bare hands before serving them. However, any food served raw or handled after being cooked can get contaminated with norovirus.

Norovirus outbreaks can also occur from food that is contaminated at the source or on the farm. This can include oysters harvested from contaminated water, or fruit and vegetables sprayed with contaminated water in the field.

Schools and childcare centers

Norovirus outbreaks also frequently occur in schools, childcare centers, colleges, and universities. Norovirus outbreaks on school and university campuses have even led to campus closures. Close quarters, shared spaces, and high-touch surfaces make it easy for norovirus to spread in schools.

Cruise ships

Norovirus is the most frequent (over 90%) cause of outbreaks of diarrheal disease on cruise ships. These outbreaks often get media attention, which is why some people call norovirus the "cruise ship virus." However, norovirus outbreaks on cruise ships account for only a small percentage (1%) of all reported norovirus outbreaks.

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. This is because norovirus can persist on surfaces for days or weeks and is resistant to many common disinfectants.

A United plane had to be taken out of service and deep cleaned after dozens of passengers flying home from a cruise started throwing up

• United Airlines briefly grounded a jet after 30 passengers fell ill with symptoms such as vomiting.
• The Boeing 737 Max was carrying dozens of passengers who were returning from a cruise.
• Two flights were canceled after the jet was taken out of service for deep cleaning.

A United Airlines plane had to be removed from service after dozens of passengers fell ill.

The Boeing 737 Max was carrying 163 passengers from Vancouver, British Columbia, to Houston on Friday.

About 75 people on board were returning from a cruise, and 30 of them fell ill, the Daily Mail reported.

The newspaper reported that their symptoms were flu-like, including vomiting and nausea.

In a statement shared with Business Insider, United confirmed that "several passengers who had been on the same cruise and did not feel well were on United Flight 1528."

The airline added that it was "actively coordinating with health authorities to address the situation."

It has not been confirmed which cruise ship the passengers came from.

Cruise Hive reported that only one was docked in Vancouver on Friday — Royal Caribbean International's Radiance of the Seas . The vessel experienced a norovirus outbreak in April.

Royal Caribbean did not immediately respond to a request for comment from Business Insider about whether Radiance of the Seas had experienced any cases of illness.

United told Business Insider its plane was temporarily removed from service for a deep cleaning "as a precautionary measure."

Data from Flightradar24 shows that two subsequent flights on Friday and Saturday, due to be operated by the same jet, were canceled. The plane did, however, depart Houston less than 24 hours after it landed.

Friday's incident was the second airline case of widespread illness within a month.

A Condor flight from Mauritius was met by emergency services as 70 passengers suffered nausea and vomiting . The airline said it was adjusting its cleaning processes as a result.

The most famous airline-vomiting incident occurred on a 1975 Japan Air Lines flight . One hundred and ninety-seven passengers fell ill, of whom 144 were taken to the hospital. It was later found that some of the meals had been contaminated by Staphylococcus bacteria, which caused food poisoning.

HOUSTON – More than two dozen people on a United Airlines flight to Houston on Friday became ill while the plane was traveling from Canada.

United Airlines flight 1528 was flying from Vancouver, British Columbia to Houston. During the flight, 25 people became sick.

According to the Houston Fire Department , the sick passengers reported symptoms of nausea.

“About an hour and a half before we hit Houston, they ask for if you’ve been on this cruise ship, could you raise your hand,” James Snell recounts from his flight.

All of the ill passengers were previously on a cruise. A total of 75 passengers flying on the plane were on that cruise.

Firefighters and paramedics met the passengers as they landed at George Bush Intercontinental Airport following the five-hour flight from Vancouver, British Columbia.

“Then all of a sudden, the flight attendant, she put on a mask, and the guy next to me is like, ‘What do you think’s going on?’ And I’m like, ‘Bro, I don’t know. You know? I mean, COVID, we’re all going to die.’ You know what I mean,” said Snell.

Three people were “evacuated” from the airplane, but no one was taken to the hospital.

MORE STORIES INVOLVING UNITED AIRLINES

According to the Federal Aviation Administration (FAA) the plane landed around 6:30 p.m.

“Then firetrucks and ambulances started pulling up,” Snell said. “They didn’t hold us very long, maybe 45 minutes-ish.”

Passengers aboard the airplane say that the pilot and flight attendants alerted them that the Centers for Disease Control and Prevention (CDC) is investigating the illness.

“This is where it got weird,” Snell said. “He [the pilot] got over the speaker, but he came out to us and he said, ‘Hey, in my 25 years of flying, I’ve never seen anything like this. We have been quarantined by the CDC. Nobody can exit the plane until the CDC lets us off.’”

After being let off the plane passengers were screened by paramedics from the Houston Fire Department.

“As soon as you got off, you got mobbed, wanting to know if you had any symptoms and did you want to be triaged,” Snell said. “But then they let us off and I thought, man, you’re letting us off in Houston airport. Like we’re going everywhere in the world. This is how it started the last time.”

The last time refers to the COVID-19 pandemic. It’s what he and other passengers thought they could be dealing with.

“We’re all trapped in this tube, and we’ve all lived through Corona. And I was just like, ‘oh, come on. Not again,’” Snell said.

KPRC2 asked the FAA, CDC, Houston Fire Department and United Airlines for information about which cruise ship the passengers who got sick were on and for the illness, but none of the organizations would provide further information.

According to information from the CDC, there have been seven outbreaks of illness on cruise ships this year.

The most recent is a norovirus outbreak on the Celebrity Summit cruise ship.

Norovirus is commonly known as the “stomach bug” and can lead to nausea, vomiting and diarrhea. It’s a highly contagious virus, but is typically not a severe illness and passes in a few days, the CDC reports.

According to Celebrity Cruises’ website , the Celebrity Summit ship is currently sailing between Seward, Alaska and Vancouver, British Columbia.

Vancouver is where the United Airlines flight full of sick passengers took off.

KPRC 2 asked Celebrity Cruises for more information about their outbreak and if it’s connected to the sick passengers that landed in Houston. We’re still waiting for an answer.

Meanwhile, United Airlines tells KPRC 2′s Gage Goulding that the plane is being pulled from rotation until it can be deep cleaned.

UNITED AIRLINES STATEMENT

“Several passengers who had been on the same cruise and did not feel well were on United Flight 1528 from Vancouver to Houston tonight. United Airlines is actively coordinating with health authorities to address the situation. As a precautionary measure, the aircraft will be removed from service and go through a deep cleaning before returning to service. Ensuring the health and safety of our passengers and crew remains our top priority.”

CDC Statement

“CDC is aware of a flight from Vancouver, British Columbia, that arrived at Houston’s George Bush Intercontinental Airport on Friday, May 31.

Public health officers from CDC’s Houston Port Health Station worked with EMS to evaluate ill passengers on board. Most of the ill passengers reported mild GI symptoms. No passengers were noted to have a fever during the flight or upon public health assessment at landing. No passengers met CDC criteria for further public health follow-up. Passengers from the flight continued with their travel plans.”
