Here are listed latest cruise ship Norovirus outbreaks on passenger ships, with information what is and how to avoid Norovirus on cruise ships, CDC reports and news updates. From the following link, you can skip the intro and jump directly to the illness outbreak reports for 2018.

Cruise Norovirus outbreaks

This survey is based on official data from CDC.gov ("Centers for Disease Control and Prevention"). CDC's "Vessel Sanitation Program" assists the cruising industry to prevent and control the transmission and spread of gastrointestinal illnesses (Noro virus, ETEC) on passenger ships calling on US ports.

Cruise Ship Norovirus - CruiseMapper CruiseMinus

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 Noro virus 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 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 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 ship facilities renovations or new ships. Inspection fees are as follow:

  • Small ships (under 3000 gross tons) pay US$ 1500 per inspection.
  • Small ships (between 3000 and 15000 gross tons) pay US$ 3000 per inspection.
  • Medium ships (between 15000 and 30000 gross tons) pay US$ 6000 per inspection.
  • Large ships (between 30000 and 60000 gross tons) pay US$ 9000 per inspection.
  • Extra large ships (between 60000 and 120000 gross tons) pay US$ 12000 per inspection.
  • Mega ships (above 120000 gross tons) pay US$ 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 cruise ship GI 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 to an 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 ship's med staff often collects stool, vomit, blood specimens, which then are send to land-based labs to confirm the illness cause.

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

  • 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 voayge's outbreak.
  • Occasionally, VSP requires the company to notify port authorities and also to perform cleaning and disinfection in cruise port terminal buildings.

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.

Norovirus on cruise ships

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

Norovirus cruise ship passenger

  • Why 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 Noro 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 Noro virus illness is not seasonal and usually not serious (in med terms). It hits 1 in 5 people annually. It is the cause for about 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 don't kill the Noro virus. 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 ships 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 of Norovirus 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 for Noro virus and what to do if you got it? Obviously, 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?

  1. Wash your hands often (hot water & soap), especially before/after eating and after using the bathroom
  2. Limit physical contacts as much as possible, pack some extra soap, a personal disinfectant (Lysol, Pepto-Bismol), oral rehydration sachets & treatments for diarrhea
  3. Avoid eating uncooked food (including salads & 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.
  4. Drink lots of water.
  5. 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 a travel insurance, it covers a 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.

sources for cruise ship Noro virus outbreaks and how to avoid Norovirus

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 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 diarrhoea 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 diarrhoea, return to your cabin and immediately report to the Medical Center or Front Office (Reception, if the infirmary is busy) by dialing 999.

The Noro cruise ship virus procedures

What 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, 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 an 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 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 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.

Zika virus illness 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, 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, 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 also issued by other governments and health agencies.
  • The CDC list of potentially dangerous for travel countries includes (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 Zika virus. Cruise ships publish daily health and safety instructions to their passengers on how to avoid mosquito bites.
  • Zika virus illness 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.
  • These links are to the Zika page at Wikipedia and to the travel warning ("Guidelines for Pregnant Women") at CDC.

The cruise ship virus conspiracy

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.

Cruise Ship Norovirus Outbreaks - CruiseMapper CruiseMinus

Some of the world's most famous passenger vessels 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 speak of 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 clear, keep your mind clear, always hope for the best. Bad, if meant to happen, will happen anyway, and nothing can change it.
