The Cruise G.I. Blues: Why We Don't Handle Gastrointestinal Virus Cases

The last several articles on this blog have involved gastrointestinal (G.I.) virus outbreaks on cruise ships.

The cruise ships involved are Holland American Lines’ Volendam and Veendam, (HAL ships, historically, are the most likely to be contaminated with norovirus), the Discovery cruise ship which was held up in Liverpool for what the cruise lines describe as “enhanced cleaning,” and most recently the Celebrity Millennium which arrived in Alaska with a bunch of sick passengers who went ashore and coughed all over the city of Seward.

These ships join the list of other sick cruise ships this year. There are seven official reports of Cruise Ship NorovirusG.I. cases so far this year documented by the U.S. Centers for Disease Control and Prevention (CDC). But the list is incomplete. The CDC requires cruise lines to report outbreaks only when a certain percentage (more than 3%) of the passengers become ill. If the cruise ship does not call upon a U.S. port, then the CDC has no jurisdiction and there is no obligation to report any G.I. cases to the U.S. federal government.

Most countries around the world don't require reporting of cruise G.I. cases. So when you read the CDC database of G.I. outbreaks on cruise ships, remember that this is only those cruises which dock at a U.S. port and where at least 3% of the passenger report to the infirmary.

My partners at my law firm ask me why I blog about G.I. cases because our firm rarely handles such cases. Why don’t we handle G.I. cases? For a couple of reasons:

It is usually impossible to prove where the virus originated. The CDC and the Food and Drug Administration (FDA) concluded long ago that most norovirus outbreaks are due to contaminated food and water. No, not due to the dirty hands of the cruise passengers as the cruise lines want you to believe, but noro-laden food or contaminated water.

But general propositions are no help in a particular case. The CDC makes no real effort to pinpoint the epicenter of the outbreak on the cruise ship.

The CDC usually can figure out the causative agent (i.e., noro, e-coli, etc.) but that’s where the federal agency’s inquiry ends. The CDC has but a few hours to board the cruise ship and conduct its Cruise Ship Norovirusinvestigation once the ship returns to a U.S port. It does not have the time or the resources to perform a full blown epidemiology assessment during the limited time the ship is in port.

Was the water well used to irrigate the potatoes or lettuce which were loaded onto the cruise ship contaminated by noro-infected swine feces that leeched into the well supplies? You will never know because no one is doing any investigation to find out.

The cruise lines don’t want such sophisticated analysis either, because the most likely cause of norovirus outbreaks is not bad passenger hygiene but contaminated food and water. It’s bad for cruise business for an official U.S. agency to point the finger at contaminated water or infected food, or to conclude that food handlers worked while infected with noro and, in turn, contaminated 150 plates of salad consumed by the passengers.

Illnesses due to e-coli or norovirus are nasty. You’re afraid that you are going to die and then you’re afraid that you’re not going to die, the joke goes. But it’s no joke. Sick passengers do die, particularly elderly passengers with suppressed immune system and especially those who are ignored by the ship doctors or those who receive bad care while on the cruise ship.

The rights of ill or dying passenger infected with norovirus on cruise ships are limited. The Death on the High Seas Act (DOHSA) prohibits the recovery of damages for elderly retirees. Their deaths are financially meaningless if they become sick during a cruise and then later die either on or off of the cruise ship. Cruise lines love DOHSA. Also, sick passengers who receive bad medical care by the ship doctors usually have no recourse against the cruise lines because the ship doctors are legally considered to be “independent contractors” for whom the cruise lines have no responsibility. And neither the cruise lines nor the CDC or FDA are trying to find out where the norovirus came from in the first place.

Cruise lines are cutting back on the testing of water, placing increasing demands on its crew members who often work while sick, hiding dirty galley equipment from CDC inspectors, and pushing their ships and staff past reasonable limits leaving little time and resources to maintain a clean and hygienic environment. 

Cruise Ship NorovirusIt’s easier for the cruise lines to blame the passengers for poor hygiene and then stand behind the CDC’s and FDA’s indifference and archaic laws like DOHSA which have insulated the cruise industry from the consequences of their negligence and recklessness for decades.

In a nutshell, we don’t handle G.I. virus cases because the deck is stacked against the cruise passenger. Cruise passengers typically don’t know when they board a noro-infected ship that they have few rights and that the cruise line will blame them if they get sick. We blog about the problem because it is an insight into the way which the cruise industry operates its business and treats its customers.

The cruise lines say that the “health and safety of cruise passengers are its highest priorities.” That’s not true. We prefer that the cruise passengers understand that before they walk up the gangway into a noro-contaminated ship.

Carnival Fascination Cruise Ship Flunks Health and Sanitation Inspection

A Carnival cruise ship has become the sixth cruise ship this year to flunk a sanitation inspection by the Centers for Disease Control and Prevention (CDC).

The Carnival Fascination failed the surprise inspection with a score of only 84. You can read the report from the CDC here.  It's full of dirty and unsanitary conditions in the galley and food serving areas, as well as problems with the recreational water supplies.

The Fascination had a problem which we are hearing about more often, that is when crew members are experiencing acute gastrointestinal illness but keep working. This substantially increases the Carnival Fascination Cruise Shipchances that they will infect other crew members and the passengers that they come into contact with. The problem is particularly critical when the infected crew are food handlers. 

Five other cruise ships have failed CDC inspections this year.

Two weeks ago we wrote about the Celebrity Summit, the Golden Princess, the Sea Dream Yacht Club's Sea Dream, and the Caribbean Fantasy operated by America Cruise Ferries all of which flunked the CDC inspections. You can read our article: Disease Breeding Grounds: Three Cruise Ships Fail Health & Sanitary Inspections

A week ago, we wrote about another Celebrity Cruises ship, the Celebrity Century, which also failed the inspection.

Report of Gastrointestinal Sickness Outbreak on Celebrity Infinity Disappears: Honest Mistake or Diabolical Cover-Up?

Those of you who read this blog regularly know that I find lots of information about things that the cruise lines would prefer you not know on Professor Ross Klein's website called CruiseJunkie.com.  A silly name I know, but the information is quite serious if you are interested in accurate information about cruise passengers and crew who disappear under mysterious circumstances, fires and collisions, and disease outbreaks on the high seas.  There is no other credible website like this anywhere which tracks such information in the cruise industry. 

Yesterday Professor Klein's website contained information about a gastrointestinal illness (GI) outbreak aboard the Celebrity Infinity cruise ship. He linked to the CDC Vessel Sanitation website which contained a report that 101 of 2086 passengers (4.84%) and 17 of 927 crew (2.05%) have reported ill Celebrity Infinity Cruise Shipwith gastrointestinal illness. Two CDC Vessel Sanitation Program environmental health officers and an epidemiologist boarded the ship on arrival in Fort Lauderdale on April 1, 2013 to conduct a targeted environmental health assessment and evaluate the outbreak and response activities. 

But when I clicked on the link to the CDC information, the website said:

"The page you requested cannot be found at this time. It may be temporarily unavailable or it may have been removed."

So what happened?  I don't know. 

Professor Klein questions whether this is a mistake of some sort or whether there is a cover-up at play.

Again I don't know. But I do know after being a lawyer for 30 years that there is a very cozy relationship between the cruise lines and federal agencies like the CDC whose surprise inspections are hardly a surprise. And last year it became obvious that after Congress passed a law requiring the cruise lines to report crimes to the FBI which had to post the data on a Coast Guard website for the public to view, these federal agencies worked behind the scenes with the cruise lines to cover the crime statistics up.  

So what's up with the CDC posting a GI outbreak and then the information disappearing?

Celebrity has had difficulties with its shipboard sanitation this year with the Summit and the Century failing CDC inspections for health and sanitation.  

Is the removal of the report of the outbreak aboard the Celebrity Infinity a mistake or is something else more sinister going on?

I'd like to hear from passengers and crew members whether there was a recent gastrointestinal illness or norovirus outbreak on the Celebrity Infinity?  Please let us know.

Am I being overly-suspicious? Maybe so. But I'd rather be paranoid than a naive sap who looks the other way while another federal agency and a cruise line play games behind the public's back.

April 7 2013 9:30 PM: The CDC report on the Celebrity Infinity has reappeared. Here it is.  Celebrity Cruises has the dubious distinction of 2 failed CDC inspections and a GI outbreak for 2013.

Another Celebrity Cruise Ship Flunks Health & Sanitation Inspection

Celebrity Century Cruise Ship - Failed CDC ScoreAccording to the Centers for Disease Control and Prevention (CDC), another Celebrity Cruises ship flunked a surprise inspection.

The Celebrity Century failed the CDC inspection, receiving a score of only 78.

Last week we reported that another Celebrity cruise ship, the Summit scored, flunked an inspection with a score of only 81. Three other cruise ships received failing scores as well.  So far this year there have been five cruise ships with failing grades. Read our article: Disease Breeding Grounds: Three Cruise Ships Fail Health & Sanitary Inspections.

The most disturbing finding was not just that the Century was dirty with contaminated food debris, but that crew members worked while ill with gastrointestinal sicknesses. Several of the ill ship employees worked in the galleys or interacted with passengers while ill.  The other cruise ships who flunked the inspections earlier this year also had ill crew members who worked with food and around passengers as well.  

These findings are significant because the cruise lines always blame the passengers when there are norovirus outbreaks and accuse the quests of not washing their hands.  The outbreaks may be due to ill employees who may be contaminating the food and infecting passengers.  

Celebrity Cruise Ship - Failed CDC ScoreYou can read the report of the Century here

The report indicates that two cruise ship cook worked while ill before reporting to the ship's medical infirmary.  A sick hair stylist worked all day around passengers before going to the medical center. And an ill gift shop attendant worked before going to the medical center and continued working after he was suppose to be in isolation.

A particularly disgusting finding was that the toilet intended for galley workers was found locked when the galley was in service, and when the inspectors opened the door, the bathroom had no toilet paper.

And you wonder why there are norovirus outbreaks on cruise ships?

Disease Breeding Grounds: Three Cruise Ships Fail Health & Sanitary Inspections

Centers for Disease Control - Cruise Ship CDC Cruise Critic is reporting that three cruise ships recently failed inspection by the Centers for Disease Control and Prevention (CDC).

The cruise ships are the Celebrity Summit, Princess Cruises' Golden Princess and the SeaDream II.  

Take a moment and read the actual CDC reports of these ships. They are disgusting.

You can understand how easily norovirus and other gastrointestinal viruses can spread after reading about cooks and food handlers working while they are suffering from acute gastrointestinal symptoms. The monitoring of water treatment on some of these cruise ships is spotty and there was even one ship using a reverse osmosis system (which is suppose to be used only when the ship is underway) that was sucking up nasty water in the ports.    

The report for the Celebrity Summit is here. You will read about several crew members, including food handlers, who were suffering from acute gastrointestinal (referred to as AGE) symptoms but were still working, including handling food. The gastrointestinal surveillance logs were not being completed. There were widespread dirty and greasy conditions with flies and insect droppings in the bars and galleys.

The report for the Golden Princess is here. The Princess Cruises ship also had crew members with acute gastrointestinal symptoms continuing to work throughout the day even though they were Celebrity Summit Cruise Shipobviously ill in the morning.  An assistant buffet steward was suffering from GI problems but worked the buffet from 9:30 Am and did not report to the ship infirmary until 4:00 PM. There were inadequate reports regarding potable water facilities.  The ship had dirty and soiled areas, including the signature Princess restaurant Sabatini's.        

The report for the Sea Dream Yacht Club's Sea Dream II is here. This is the ship that was operating its water system continuously, including at port, and had been doing so for years. There were also dirty and unsanitary conditions noted.

The next time there is a norovirus outbreak and the cruise line instantaneously blames the passengers for not washing their hands, there may be a lot more to the story.

March 27, 2013 Update: In reading cruise expert Professor Ross Klein's website, I realized that Cruise Critic omitted another failed CDC score by the Caribbean Fantasy operated by America Cruise Ferries. You can read the report here. The deficiencies include failing to maintain acute gastrointestinal sickness logs, potable water deficiencies, galley and potwash cleaning shortcomings, and the failure to maintain cleaning equipment in proper order including several dish-washing machines and conveyors which had been not in proper condition for over a year.

Norovirus Outbreak on Rhapsody of the Seas in Fiji - Cruise Ship Quarantined

Cruise Norovirus - Rhapsody of the SeasThe Fiji Broadcasting Corporation (FBC) reports that a Royal Caribbean cruise ship berthed at the Suva Wharf in Fiji was quarantined today by authorities following what is described as an outbreak of norovirus. The Health Ministry in Fiji reportedly confirmed 51 cases of the contagious virus on board the Rhapsody of the Seas which is carrying around 2300 passengers and 870 crew.

The FBC states that affected passengers have been isolated and no one is allowed to enter the quarantined area on the ship except the medical response team. 

The cruise ship will leave Fiji for Noumea, New Caledonia later tonight.

Because this outbreak occurred on a cruise ship which did not call on a U.S. port, it will not be reported to the Centers for Disease Control (CDC).

You can get norovirus from an infected person, contaminated food or water, or by touching contaminated surfaces.

The Rhapsody of the Seas experienced a norovirus outbreak the last week of August when 53 of 2,129 passengers (7.19%) experienced vomiting and diarrhea.

October 31, 2012 Update: Cruise ship under quarantine leaves Fiji.

Small Cruise Ship Sanitation Blues: Grand Mariner Flunks the Fed's Galley Inspection

Cruise Ship SanitationCruise Critic reports today that just one month after HAL's Veendam flunked an inspection by the Centers for Disease Control (CDC), the Blount Small Ship Adventures Grand Mariner's 100 passenger cruise ship also failed a CDC inspection: 

"Moldy ice-cubes, inadequate monitoring of food temperatures, raw meat stored with nonmeat items, ingredient containers left open, dirty dish-washing sinks" and 31 other violations earned the ship the failing score of 75 out of 100.

Wow.  Sounds like the kitchen in my college apartment.  And people pay money to cruise and eat on these ships? 

HAL's Veendam Flunks Health Inspection

Below is a CNN video regarding the 16 year old Holland America Line's Veendam cruise ship which failed an inspection conducted by the Centers for Disease Control.

We blogged about this incident last week in our article:

"Gross! Holland America Line's Veendam Flunks Health Inspection."

CNN described the ship conditions as "really gross:"

 

 

Gross! Holland America Line's Veendam Flunks Health Inspection

Dirty Cruise Ship - CDC - Failed InspectionFlies. Dirty and malfunctioning ice machines, refrigerators & dishwashers. More flies. Dust, dirt, food residue, and debris. Flies and more flies. Flies where food is prepared. Flies where food is stored. Ugh. These unsanitary problems are part of a ridiculously long list that the U.S. Centers for Disease documented during a surprise inspection last month aboard the Holland America Line's Veendam cruise ship.

You can read the gross report here.

The inside word is that most "surprise" inspections are not surprises at all.  Most of the time the cruise lines are tipped off and immense pressure is suddenly applied on the crew to bring the ship up to standards. But here, at least, there was no advance warning. And this is what you get.  

The last cruise ship to fail such an inspection was the Monarch of the Seas last December - Dirty Dishes & Fruit Flies Flourish on Royal Caribbean's Oldest Cruise Ship. That was pretty gross too. 

 

Norovirus Update: Celebrity Constellation Cruise Ship is Latest to Join List of Sick Ships

A number of cruisers have been contacting our office asking about a sickness outbreak aboard the Celebrity Cruises' Constellation cruise ship. 

The Centers for Disease Control ("CDC") officially placed the Constellation on its vessel sanitation list of ships with sickness.  The Constellation sailed on January 28th from Fort Lauderdale and returned yesterday, February 11th. 

95 out of 1,992 passengers reported being ill during the voyage (4.77%).  12 crewmembers reported being ill. The sick passengers and crew reported symptoms of vomiting and diarrhea.

Only cruise lines calling on U.S. ports are required to report disease outbreaks to the CDC.  Cruise Celebrity Cruises' Constellation Cruise Ship - Norovirus?lines are required to make the report only when 3% or more of passengers or crew reported symptoms of diarrheal disease to the ships medical staff during the voyage.  Under-reporting occurs regularly because many passengers can't make it away from their toilets due to diarrhea, and some passengers don't want to be confined to their cabins. 

This is the fifth "official" cruise ship sickness outbreak which has found its way onto the CDC database which lists the Celebrity Silhouette, Celebrity Constellation, Royal Caribbean Voyager of the Seas, Princess Cruises' Crown Princess and P & O Cruises Aurora cruse ships.  The CDC data does not include the outbreak on Princess Cruises' Ruby Princess, which we reported on last week

The CDC has confirmed norovirus only on the Crown Princess and Aurora.  It is disappointing that the CDC can't figure out the type of disease on the other ships.  In no cases did the CDC pin-point the cause of the outbreak, to either a virus brought on the cruise ships by a passenger, or unsanitary handling of food by a crew, or infected food and/or water.  If the CDC can't figure out how the outbreak occurred, it seems hard to respond to the problem and eradicate the causative factors.

There has been a lot of criticism on how Celebrity Cruises handled the latest outbreak on the Silhouette.  You can read the comments by passengers here.   

How did Celebrity Cruises handle the outbreak on the Constellation?  If you were on the cruise, please leave her comments below, pro or con.

November 5, 2012 Update:

News sources are reporting that the Constellation suffered another outbreak of norovirus, this time during a 12 day cruise which just returned to Southampton.  BBC reports that 350 passengers became ill with vomiting and nausea. Read our article: Cruise Puke Fest: Norovirus Strikes Celebrity Constellation. if you were ill on that cruise please leave a comment at the end of that article.

Dirty Dishes & Fruit Flies Flourish on Royal Caribbean's Oldest Cruise Ship

Cruise Ship - Centers for Disease Control - CDCIn a story widely reported in the national media, the Centers for Disease Control failed Royal Caribbean's Monarch of the Seas after conducting a surprise vessel sanitation inspection last month. 

On November 18, 2011, CDC inspectors boarded the Monarch of the Seas, which is the cruise line's oldest vessel, and found numerous public health risks and violations if the CDC's sanitary standards.

The popular online cruise community, Cruise Critic, first reported on the nasty situation, followed by the USA Today cruise blog, CruiseLog.  

The CDC found a whopping 43 unsanitary conditions and "deficiencies" in the cruise ship's procedures which were in violation of the CDC's Vessel Safety Program (VSP) manual.  Included in the report were the following:

  • Dish-washing equipment in poor condition;
  • Improper cooling temperatures for stored provisions;
  • Improper cooking temperatures for cooked food;
  • Accumulations of food debris in wash and rinse areas;
  • "Clean" plates soiled with food residue;
  • Soiled plates stacked with clean plates;
  • Waiter stations, food preparation counters, slicers, and strainers soiled with dirt and food particles;
  • Live and dead fruit flies on food preperation surfaces throughout the galley; and 
  • Improper procedures for public toilets, shower-head disinfection, and disease outbreak and prevention.   

You can read the complete inspection report here

Cruise Ship Fruit FliesIt is rare for a cruise ship based in the U.S. to fail a CDC inspection.

For a cruise line which spent billions on its gigantic new Genesis class cruise ships the Oasis and the Allure of the Seas, it looks like its oldest cruise the Monarch is showing significant signs of neglect which risk sickening its passengers. 

Anyone who sailed recently on the Monarch care to leave a comment?

CruiseLog's Article on Cruise Ship Sickness Misses the Boat

The popular cruise blog written by Gene Sloan for the USA Today newspaper published an article yesterday entitled "Outbreaks of Illness on Cruise Ships at Multiyear Low."

CruiseLog cites statistics from the U.S. Centers for Disease Control ("CDC") of 11 outbreaks of illnesses so far in 2011, down from 14 in 2010 and 15 in 2009.  It concludes that this reflects a "downward trend that began several years ago as the industry increased prevention efforts."

But looking at the data at the CDC website, you can see that the "trend" is actually flat, with 14 to 15  outbreaks reported to the CDC for each the past 3 years (2008, 2009 and 2010).  This year will probably end up with the same number of reported incidents.

There has been an additional outbreak reported to the CDC just since the CruiseLog article was published yesterday.  HAL's Ryndam cruise ship has reported that more than 5% of its passengers reported to the ship's infirmary complaining of vomiting and diarrhea. You can read Cruise Ship Sicknessabout this latest outbreak here.  The cruise ship is returning to Tampa tomorrow.

Unfortunately, there seems to be an outbreak or two over the Christmas and New Year sailing somewhere each year, so we should reasonably expect there to be the usual number (14 to 15) this year as in past years.

My real criticism of the CruiseLog article is not whether the number is actually 15 versus 11.  It is that the article really doesn't explain that the cruise ship outbreaks reported to the CDC are probably less than 50% of the actual number of incidents which occur around the world each year.  Remember that cruise lines do not report sickness outbreaks to the CDC if the cruise does not call on a U.S. port.  This is significant because many cruise lines re-positioned a greater number of their cruise ships to Europe and Asia in recent years compared to five years ago

Although it is difficult to track the incidents outside of the U.S., we have reported on a number of incidents this year. 

For example, in September, norovirus broke out on Celebrity's Eclipse sailing out of Southampton, England. Royal Caribbean's cruise ships sailing out of this U.K. port remained on heightened alert for months.  You will find no mention of this is in the official CDC database.  The cruise lines certainly will never voluntarily disclose this.

In November, we reported on one death and 80 sick passengers on HAL's Veendam which Holland America Line Veendam Cruise Ship Norovirus?experienced a sickness outbreak as the cruise reached in Rio de Janeiro.  

The other issue that the CruiseLog does not explain is the cruise lines report disease outbreaks only when 3% of passengers are afflicted based on the number of ill passengers who appear in the ship infirmary.  This is significantly less than the true number of those afflicted with viral illnesses.  Many sick passengers know that they will be quarantined in their cabins or they simply do not want to wait in the long lines outside of the ship infirmary. 

The Clinical Infectious Disease Journal reported earlier this year that 40% of passengers with a viral infection did not report being sick to the ship medical staff.  If these passengers were included in the sickness count, then the number of CDC reportable cases would surely increase.   

CruiseLog also points to Carnival as not reporting a single outbreak this year.  Does that mean that Carnival has a vaccine against the cruise ship bug?  Hardly.  Consider the following comments by cruise passengers on the CruiseJunkie website about the Carnival Conquest last week:

"From a passenger: There was an outbreak of something vomiting and diarrhea starting on Tuesday of the cruise (4-11 Dec). My husband got sick on Thursday morning and was asked to stay in cabin on isolation. On Friday I came down with vomiting and diarrhea. We were told there were lots of people sick.

Another passenger writes: On our final day at sea suddenly all the crew was wearing gloves and none of the passengers were allowed to get their own plate or food at the buffet.  Everything had to Cruise Ship Norovirusbe served by the staff and they were constantly wiping down everything and making announcements about hygiene.  We asked if something was going on and we were told no however by that night 3 of the seven people in our party were very sick and once we walked in on an employee in the bathroom vomiting very badly.  A casino employee told us that night many of the crew and passengers were very sick. 

When we were getting off the boat Sunday we saw stacks and stacks of mattresses in plastic they were loading on the ship.  We still have people from our group sick and I wish we had been told something.  We received no information and since I was traveling with two children and my seventy year old father I continue to be concerned." 

Families intending to cruise and worried about norovirus should read news sources like CruiseLog with a grain of salt.  There is no empirical evidence that norovirus and other cruise ship sicknesses are on the decline. 

Regarding cruises not calling on a U.S. port, the best sources of information are anecdotal, like cruise community forums and websites not beholden to the cruise lines like Professor Ross Klein's CruiseJunkie.

Norovirus Aboard Celebrity Solstice Kills Father of Eight

Courthouse News Service reports that a lawsuit has been filed against Celebrity Cruises for the death of a father of eight after he died from incompetent medical care for norovirus he contracted during a vacation cruise aboard the Celebrity Solstice

The lawsuit alleges that Joseph Gavigan Jr., from Orleans, Massachusetts, embarked the Solstice cruise ship in January of this year in Fort Lauderdale, Florida.  During the cruise, a norovirus outbreak occurred and Mr. Gavigan contracted the illness.

The lawsuit alleges that Celebrity failed to take adequate precautions to screen passengers and crewmembers, failed to sanitize and disinfect the cruise ship and disinfect plates, cups, food trays, Joseph Gavigan Jr. - Norovirus - Celebrity Solstice Death utensils, ice machines and drinking fountains, failed to quarantine infected passengers and crewmembers and failed to warn Mr. Gavigan about the virus. 

The lawsuit also alleges that Celebrity provided negligent medical care to Mr. Gavigan, and negligently selected the cruise ship medical staff who held themselves out as agents of the cruise line.

A copy of the lawsuit is available on line and can be viewed here.  The lawsuit was filed by attorney Keith Brais, a very experienced maritime lawyer who used to be a defense lawyer for Celebrity Cruises and other cruise lines.  

The Centers for Decease Control and Prevention reports that 118 cruise passengers and 10 crewmembers reported ill during the voyage.  You can read more about the CDC's report for this voyage aboard the Solstice here.  

The popular on line community Cruise Critic contains Celebrity's official press statement about the norovirus outbreaks (which preceded Mr. Gavigan's cruise) as well as the accounts of unhappy cruisers some of whom felt that the medical staff was incompetent and the cruise line was trying to cover-up and down-play the outbreaks. 

An on line obituary indicates that Mr. Gavigan, nicknamed "Junior," is survived by 21 grandchildren and 17 great grandchildren in addition to his 8 children and companion.

New Study Reveals Little New About Norovirus on Cruise Ships

The medical journal "Clinical Infectious Diseases" published an article entitled "Disease Transmission and Passenger Behaviors During a High Morbidity Norovirus Outbreak on a Cruise Ship, January 2009."

Of some 1842 passengers on the cruise ship, 1532 (83%) returned questionnaires provided by the researchers.  236 (15%) met the norovirus definition.  

Cruise Ship Norovirus This particular cruise had a passenger vomit in a public area during boarding, as well as 7 other incidents where passengers vomited in public.  The Centers for Disease Control ("CDC") investigators concluded that some sick passengers may have been infected by the vomit (through aerosolized vomit or by touching contaminated surfaces) or they were infected by person-to-person contact, particularly by an ill cabin mate. 

The CDC investigators also concluded that some of the public toilets on the cruise ship were out of hand soap and paper towels and dish washing machines did not do an adequate job sanitizing eating utensils.  These shortcomings might have contributed to the outbreak.

Nothing new with these conclusions.

The two interesting points in my opinion revealed in the study:

Of the 236 ill passengers, 95 (40%) did not report to the infirmary.  We have been told by many passengers on cruises plagued by norovirus that the actual number of sick passengers reported by the cruise lines to the CDC was far less than the actual number of passengers with norovirus.  Cruise lines report only the number of passengers who report to the ship infirmary.  This is a problem we have discussed before - Is Celebrity Cruises Under-Reporting Sicknesses to the CDC?

Perhaps the most interesting statistic is that 62% of ill passengers did not decrease their participation in public activities.  Over 200 passengers ill with norovirus walking around the ship?  Yuck.  This undoubtedly led to the spread of the outbreak.

But most outbreaks of norovirus on cruise ships are no so clear cut.  There appears to be no effort to scientifically determine the source of norovirus outbreaks.  

As we have reported in prior blogs,  the U.S. Food and Drug Administration (FDA) concludes that whereas "person to person" transmission of norovirus has been documented, "norwalk gastroenteritis is transmitted by the fecal-oral route via contaminated water and foods."  The FDA reports that "water is the most common source of outbreaks and may include .  .  . water stored aboard cruise ships."

When will the CDC conduct a recent study analyzing the potable water and food products after an outbreak?  Compare this study with a study by the CDC in 2002 which the CDC "suspected that initial infection among passengers on cruise 1 originated from a common food or water source and then continued to spread from person to person" and "we identified that eating breakfast at restaurant A on day 2 of the cruise was associated with illness . . ."  Or consider "Characterization of a variant strain of Norwalk virus from a food-borne outbreak of gastroenteritis on a cruise ship in Hawaii" (pin-pointing fruit at a buffet as the likely culprit).
 

Read some of our other articles about cruise ship norovirus:

Cruise Ship Norovirus - Clean the Damn Toilets!

"Cruise Ship Sickness" - Is Norovirus In The Food and Water?

Cruise Ship Norovirus - Something in the Water?

March 24, 2011 Update:  USA Today's CruiseLog has a story today about this study, indicating that the study involved Celebrity Cruises' Mercury cruise ship in January 2009.  As we pointed out in an earlier blog, the CDC investigated outbreaks on the Celebrity Mercury in  January and February 2009. 

The interesting thing about the Mercury was that it experienced four cruises a year later, in 2010, with repeated outbreaks of norovirus until the CDC took the unprecedented step of issuing a no sail order, an event we covered last March: Centers for Disease Control: "Shut Mercury Cruise Ship Down!"   It would have been interesting for the CDC to have studied the cause of the norovirus on this cruise ship for months in early 2010.  Why did this particular cruise ship experience so many problems with norovirus?  Certainly it was not just because a passenger puked on embarkation in January 2009?

Royal Caribbean's Radiance of the Seas - First Sick Cruise Ship of 2011

The Centers for Disease Control and Prevention (CDC) has listed Royal Caribbean's Radiance of the Seas as the first cruise ship in 2011 to suffer gastrointestinal illness affecting more than 2% of the vessel's passengers.

The CDC's Vessel Sanitation Program website has indicated that 150 of 2336 (6.42%) of the Royal Caribbean passengers reported being ill during the cruise on the Radiance from January 3 - 8, 2011.  The CDC information on the Radiance can be seen here

Radiance of the Seas - Norovirus? - Tampa Local 13-News station has the headline "Sick Cruise Ship Docked at Tampa Port," indicating that vacationers on board suffered from vomiting and diarrhea. The illnesses will delay the ship from returning to sea later today. The station indicates that the cruise ship's departure will be delayed approximately five hours, until 9:30 p.m., "so crews can sanitize the vessel."

The cruise line is advising cruise passengers who have recently experienced gastrointestinal illness should reschedule their cruise.  The CDC is reporting that the cruise line's response to the outbreak is "increased cleaning and disinfection procedures." 

The CDC at this point has not determined whether norovirus is causing the outbreak, nor the source of the "causative factor."  If norovirus is involved, most outbreaks of norovirus are from food and water, not by person to person contact as the cruise lines claim. 

As we have reported in prior blogs,  the U.S. Food and Drug Administration (FDA) concludes that whereas "person to person" transmission of norovirus has been documented, "norwalk gastroenteritis is transmitted by the fecal-oral route via contaminated water and foods."  The FDA reports that "water is the most common source of outbreaks and may include water from municipal supplies, well, recreational lakes, swimming pools, and water stored aboard cruise ships."

When stories like this occur, the cruise lines blame the passengers and tell them to wash their hands. The cruise ships then spray cleaning fluids everywhere.  But no one ever reveals whether the ship's food and water have been tested and the results of the tests.

The Radiance of the Seas had norovirus outbreaks before.  One passenger took this video of nasty looking tap water on the Radiance on a prior cruise.  An equally disgusting video of brown water on a Carnival cruise ship is here.  

But the winner of the gross-cruise-tap-water award goes to Carnival and is shown here.

Does anyone have video for this cruise?

Were you on the cruise?  How did Royal Caribbean handle the situation?

January 8, 2010 Update:

Passengers on the cruise arre beginning to leave comments, below, that the ice may have been contaminated, that this was a "vacation from hell," and there were way more than 150 passenger  sick.  A few passengers say they still had a great time . . .

Norovirus Update on Celebrity's Mercury Cruise Ship - March 21st Sailing

A local news station in Charleston South Carolina is reporting that passengers aboard the Mercury cruise ship on the March 21st sailing are ill.  The story is entitled  "Five Cases of Norovirus on Celebrity Mercury Cruise Ship."

The article suggests that the information came from the cruise line, although I do not see a quote or a press release from Royal Caribbean / Celebrity.  The article is rather vague, as I'm sure it's more accurate to say that some passengers have norovirus-like symptoms.  Stool samples have to be taken and analyzed ashore before anyone can conclude that norovirus exists. (There is still no official determination regarding the cause of the last round of sickness on the Mercury).  

Mercury Cruise Ship - Celebrity Cruises - Norovirus?If this information is accurate, five cases of gastrointestinal sickness is not particularly significant.  The Centers for Disease Control (CDC) "Vessel Sanitation Program" does not require the data to be reported until at least 2% of the passengers are affected (around 37 passengers).

It is possible that all five passengers were infected before they boarded the cruise ship, because there are reports of norovirus ashore of course.  It is also possible that they contracted a virus after they boarded.

We have received a number of calls and emails asking for information about the Mercury's March 21st sailing.  Here are some suggestions:

The Cruise Critic message board has a posting "People are Sick Again on the Mercury," where there is mention of a small number of passengers who may be ill.  The cruise community message boards are sometimes a good source of information, particularly when the cruise lines are not forthcoming with information.

I have found that the CDC eventually responds to e-mails and telephone calls.  The email for the CDC is cdcinfo@cdc.gov - be sure to include "Celebrity Mercury Cruise Ship - March 21st sailing" in the title of your email.  The telephone number is 800-232-4636.

The PR person at Royal Caribbean who handles crisis management statements, including norovirus outbreaks, is Cynthia Martinez.  Her email is CynthiaMartinez@rccl.com  I would be interested if anyone receives a response. 

We often hear from passengers directly from the cruise ships.  If we hear something, we will update this article.

March 27, 2010 Update:

The Charleston Regional Business Journal reports that the Mercury has only 6 sick passengers -"Celebrity Mercury Sees Huge Dip in Sickness After Extra Cleaning Measures."  Good news for Celebrity Cruises and the next round of passengers who will be sailing this Monday, March 29th.

Celebrity's Mercury Cruise Ship - Free of Norovirus?

So far, no one is reporting an outbreak of sickness aboard Celebrity Cruises' Mercury cruise ship for its latest - March 21st - sailing.  This is good news after the last three disastrous cruises.

Today's South Carolina Post and Courier newspaper runs the headline "Mercury Appears Free of Norovirus" in which the newspaper reports: "after several days at sea, the Celebrity Mercury seems finally free of a stomach bug that afflicted nearly 1,000 passengers on its previous three voyages Norovirus - Cruise Ship - Contaminated Food, Water - Infected Food Handler? from Charleston." 

The Cruise Critic message boards for the Mercury also seem to suggest that there is not a problem with gastrointestinal sickness, yet.  

The question remains what was the cause of the last illness outbreak on the Mercury?  Was it norovirus?  Was it transmitted due to contaminated water or food?  An infected food handler?  

So far the Centers for Disease Control (CDC) have not said.

Let's hope that the cruise ship passengers do not get sick for the remainder of the cruise.    

If you are on the cruise and know otherwise, let us hear from you.  Otherwise, enjoy your cruise!

Is Celebrity Cruises Under-Reporting Sicknesses to the CDC?

The Centers for Disease Control (CDC) reports that 406 of the 1829 passengers (22.1%) aboard Celebrity's Mercury cruise ship have reported fever, vomiting, and/or diarrhea.  These CDC statistics are based entirely on the information provided by the cruise line.

In the past week, we have received information from crew members that although they were sick, they were required to continue working.  This raises the issue whether the cruise line is not reporting all ill crew members to the CDC.

We just received the following comment from a passenger, who suggests that you can't trust the official CDC numbers:  

"We just got back from this cruise March 18th (one day early) and we were ready to come home. Don't believe the official count of sickness on this boat, I became ill on the second night out around 2 AM. At around 8 AM, my wife called for medical attention and was told they would be to see us in our cabin. We waited. At 5 PM, my wife called medical again and were told they had no record of our calling earlier but the medical crew was on its way around the ship and they would be to our cabin soon. As of today, March 19th., no one from medical has seen me yet unless they saw me passing in the hallways. I heard of many others who were sick and were not seen as well.

My suggestion if you decide to go, carry your own medication with you and be prepared to quarantine yourself to protect others while you are sick if you do get sick. Room service is good."
 

Celebrity's Mercury Hit By "Cruise Ship Sickness" Again

Celebrity Cruises' disastrous string of "diarrhea-cruises" out of South Carolina continues with the cruise line's decision to return the Mercury to port in Charleston a day early.

USA Today's Cruise Log reports that sickness has marred three straight voyages in "Celebrity to End Cruise Out of Charleston Early as Outbreak Continues."  Royal Caribbean indicates that 342 of the 1,829 passengers on the cruise ship became ill since the cruise began.  The article mentions that the cruise ship will skip its scheduled stop in Tortola British Virgin Islands and head straight back to the U.S.  The cruise ship will arrive in Charleston on Thursday.

Celebrity Mercury Cruise - Sick Ship?This is now the third cruise on the Mercury where passengers have become sickened with a gastrointestinal sickness.  

The USA Today article reads not unlike the typical cruise line press release - mentioning that norovirus is the most common cause of stomach illness in the U.S. and breaks out regularly in schools, nursing homes, and hospitals.  But the article does not inquire into the specific cause of this outbreak, nor question why three straight cruises have sickened passengers.

The report from the Centers for Disease Control (CDC) on the Mercury's last cruise does not even contain a conclusion regarding the "causative agent" for the sickness and is a week out of date.  If the CDC can't pinpoint the type of virus or pathogen from last week's cruise - why does anyone think that another round of "top-to-bottom" cleaning will make a difference?  

As we have reported in prior blogs,  the U.S. Food and Drug Administration (FDA) concludes that whereas "person to person" transmission of norovirus has been documented, "norwalk gastroenteritis is transmitted by the fecal-oral route via contaminated water and foods."  The FDA reports that "water is the most common source of outbreaks and may include water from municipal supplies, well, recreational lakes, swimming pools, and water stored aboard cruise ships."

What are the test results of the cruise ship's water supplies?  The Mercury is one of Celebrity's oldest cruise ships, and is scheduled to leave the Royal Caribbean - Celebrity fleet later this year. Is there something wrong with this ship?  Is this a sick ship?

"Cruise Ship Sickness" - Is Norovirus In The Food and Water?

 

Here is a statement from Celebrity Cruises / Royal Caribbean issued today:

During Celebrity Mercury’s current sailing, a number of guests onboard experienced a gastrointestinal illness, thought to be a norovirus.  Over the course of the sailing, crew onboard has been conducting enhanced cleaning, to help prevent the spread of the illness. 

While there was a decline in the spread of the illness during the sailing, in an abundance of caution, and in order to prevent additional guests and crew from becoming ill, we have decided to bypass Celebrity Mercury’s port of call today to Tortola, British Virgin Islands, and return to Charleston a day earlier than originally scheduled.  Celebrity Mercury will now arrive in Charleston early Thursday morning.  The enhanced cleaning of the ship, all of which is being done in close coordination with the U.S. Centers for Disease Control and Prevention, will continue until the ship arrives in Charleston.

“I would like to apologize for the inconvenience this modified itinerary will cause our guests currently on Celebrity Mercury,” said Daniel Hanrahan, president and chief executive officer of Celebrity Cruises.  “I have made this decision to delay the sailing because we want to maintain our high health standards onboard our ships, while providing our guests with the best cruise experience possible.  The extra time we are taking to sanitize the ship will help prevent any additional guests from becoming ill.”

March 15, 2010 Update:

Centers for Disease Control: "Shut Mercury Cruise Ship Down!"

"Cruise Ship Sickness" - Is Norovirus In The Food and Water?

The Centers for Disease Control (CDC) reports numerous outbreaks of norovirus on cruise ships operated by Celebrity Cruises, Cunard, Holland American Lines, and Royal Caribbean. 

Every time there is an outbreak, the cruise lines blame the passengers who board the cruise ships.  The media picks up in this theme and often reports that the problem is not with the cruise ships but the passengers who board the ships already infected with norovirus.  For example, in a recent article in the New York Times Travel Section "Stomach Bug Hits Cruise Ships," respected journalist Michelle Higgins writes " . . . the contaminated ships have since been disinfected  . . .  but Norovirus - Cruise Ship - Contaminated Water?such measures can’t prevent a sick passenger from coming aboard and infecting others."  Ms. Higgins suggests that " the best defense is simple: wash your hands."

Unfortunately, the issue is not so simple.

According to the U.S. Food and Drug Administration (FDA), whereas "person to person" transmission of norovirus has been documented, "norwalk gastroenteritis is transmitted by the fecal-oral route via contaminated water and foods."

Contaminated Water Supplies On Cruise Ships?

The FDA indicates that contaminated water is one of the most likely causes of norovirus.  The FDA reports that "water is the most common source of outbreaks and may include water from municipal supplies, well, recreational lakes, swimming pools, and water stored aboard cruise ships.

So whereas you always hear reports of extra cleaning of the bathrooms and cabins on infected cruise ships, there is never a mention of whether the potable water is tested and the results of the testing.

Contaminated Food Supplies On Cruise Ships?

In addition to water supplies on cruise ships being a potential source of the virus, food supplies on cruise ships can also sicken the passengers.

The FDA reports that "shellfish and salad ingredients are the foods most often implicated in norwalk outbreaks. Ingestion of raw or insufficiently steamed clams and oysters poses a high risk for infection with Norwalk virus. Foods other than shellfish are contaminated by ill food handlers."

It would be interesting to determine the job positions of the crew members infected with norovirus.  For example, the CDC reports that sixty-nine crew members were reported ill on Celebrity's Mercury and Millennium cruise ships during recent cruises.  How many of these crewmembers were cooks, waiters or food handlers?  

Norovirus - Cruise Ship - Contaminated Food?The issue of eating oysters and other shellfish on cruise ships presents a double whammy.  Cruise ships dump sewage 12 miles from shore, and the fecal material can contaminate shellfish which filter-feed.  Both cruise passengers and people ashore can then be infected by eating contaminated shellfish. 

Uncertainty Regarding Cause of Virus and Transmitting Agent

Although the CDC tries to determine the "causative agent" of the outbreak, this means that they are trying to determine the nature of the pathogen (i.e., whether it is norovirus or some other virus).  But the CDC does not report whether the virus came from a person boarding the cruise ship or, the more likely scenario if the FDA is correct, from contaminated food and water on the cruise ship.

The issue arises where do the cruise lines obtain their potable water?  From U.S. based vendors or from the Caribbean islands?  What testing is done at the ports before the water is brought aboard?  Where do the food products come from?  Is any of the food inspected by the FDA before it is loaded on the cruise ships?  

The CDC reports that around 600 passengers became ill on Celebrity's Mercury cruise ship on the last two cruises alone.  Are we to believe that all 600 people simply failed to wash their hands?  Or is there something in the food and water? 

Cruise lines should be required to publicly report the test results of the cruise ship's water samples, so that the U.S. public can determine the true cause of cruise ship illnesses.

If contaminated water is the culprit, all of the external cleaning of cruise ship surfaces is not going to solve the problem.   

Additional Information: 

Passengers can track the reported outbreaks on the CDC web page which tracks "Outbreak Updates for International Cruise Ships."  Not all norovirus outbreaks are required to be reported to the CDC and the CDC website is incomplete. 

A good source for additional information is found on "Illness Outbreaks on Cruise ships."  We have reported on numerous cases of cruise line illnesses in prior articles

Celebrity Cruises' Mercury Returns to Port with 182 Sick Passengers - Sailing Postponed

The Centers for Disease Control (CDC) reports that Celebrity Cruises' Mercury cruise ship has returned to Charleston, South Carolina with 182 ill passengers. 

According to its web page "Investigation Update on the Mercury,"  t'he CDC reports 182 of 1749 passengers (10.41%) are ill with diarrhea and vomiting, and 14 of the 850 crew (1.65%) are sick.

With the sick passengers disembarking, another 1,800 passengers are boarding.  (I wonder whether the cruise ine discloses to the new passengers which cabins had sick passengers in them?) 

Cruise Ship Norovirus

The Mercury has experienced more than its fair share of problems in the last month.  There was a report of carbon monoxide poisoning on February 13th when the cruise ship returned to Baltimore.  After the ship re-positioned to Charleston, its inaugural cruise from that port resulted in over 400 passengers coming down with the dreaded norovirus

The ship was delayed a day until February 26th for what the cruise line calls "enhanced cleaning," and we questioned "Will the Celebrity Mercury Infect Another Round of Passengers?"

Now close to 200 people another passengers and crew have fallen ill.   

The most troubling information is that the CDC reports that the "causative factor" (i.e., whats causing the sickness) is "unknown." 

Norovirus can be caused by sick passengers coming aboard, or sick crewmembers greeting the passengers or, more concerning, infected food and/or water supplies.  The cruise supporters always blame the passengers for not washing their hands - which may be the case.  But the issue whether there is a problem with the cruise ship cannot be excluded.  Many people refer to Cruise Ship Sickness - Norovirus - Ill Passengers - Sick Crew norovirus as the "cruise ship sickness."

If the potable water or food have norovirus particles, all of the external cleaning in the world is not going to make a difference.  It only takes a few fecal particles in the food, drinking water or shower.

USA Today reports that the Mercury's departure today is delayed for another round of "enhanced cleaning."  

But without determining the "causative factor" and determining whether the passengers, the crewmembers, or the food and water supplies are spreading the virus - it seems like the cruise line is shooting into the dark.

Stay tuned.

Additional Passengers Sickened on Mercury Cruise Ship

Celebrity Cruises is again reporting that at least 55 passengers have fallen ill on its Mercury cruise ship with norovirus-like symptoms. 

In a prior article we questioned: Will the Celebrity Mercury Infect Another Round of Passengers?

Here We Go Again

A local news source in South Carolina, the Palmetto Scoop, reports on the latest cruise Cruise Ship Norovirus - Sick Passengersship sickness in an article entitled "Sickness Again Plagues Charleston Cruise Ship:" 

The crew of the Celebrity Cruises “Mercury” ship, which docks in Charleston, thought they had thoroughly sanitized the vessel after nearly one-quarter of the 1,800 travelers came down with a norovirus-like illness on their last voyage. 

Turns out they didn’t do a very good job.

The Mercury ship set sail from Charleston on Saturday and within days, dozens of passengers became sick.  As of Friday, 55 of the 1,880 travelers had fallen ill with the norovirus stomach bug.

Norovirus is a disease common to cruise ships because it is highly contagious and affects confined communities. The unpleasant disease usually runs its course after a day or two and spreads through food, water, or person-to-person contact.

Celebrity Cruises has based the Mercury in Charleston, South Carolina where officials have reported twice as many cases of norovirus as normal this winter. The Associated Press reports that the virus may have come aboard the cruise ship by passengers, crewmembers or infected supplies.

 

 

 

 

 

Celebrity Cruises is owned by Royal Caribbean Cruises whose cruise ships have experienced a large number of norovirus cases this season. 

Other Royal Caribbean Cruise Ships Experiencing Widespread Illness

The Huffington Post reports that at least 310 passengers were sickened aboard Royal Caribbean's Vision of the Seas. A spokeswoman for the Brazil's National Agency for Sanitary Vigilance stated that the sickness was caused by "some kind of food poisoning aboard"  the cruise ship.  Earlier this week, Brazil ordered all 1,987 passengers and 765 crew members to remain on the ship anchored near Rio de Janeiro.  The passengers were just recently permitted to leave the ship. 

Royal Caribbean's Jewel of the Seas and Celebrity Cruises' Millennium cruise ships have also reported of a large number of ill cruise passengers. According to the Centers for Disease Control (CDC) 102 passengers and 14 crewmembers suffered gastrointestinal illness on the Jewel of the Seas, and 157 passengers and 23 crewmembers became ill on the Millennium

You can track cruise norovirus cases via the CDC has a web page which tracks "Outbreak Updates for International Cruise Ships," although not all cruise illnesses are required to be reported to the CDC.  For example, the recent outbreak of illness on the Vision of the Seas was not reported to the CDC.

Cruise Ship Norovirus - Clean the Damn Toilets!

The Clinical Infectious Disease Journal issued a report yesterday after studying why norovirus infection outbreaks occur frequently on cruise ships. 

The results were quite telling. Cruise lines always blame the passengers whenever a norovirus outbreak sickens a cruise ship. Some cruise lines know when they have a "sick ship" on their hands. Yet, the cruise line's PR department or sales team will issue a report, exculpating the vessel and crew, but blaming some poor bastard who had the misfortune of buying a cruise ticket and sitting on a dirty toilet seat on the cruise ship.

Well finally we have a credible report.  Not some pile of propaganda from the PR people at the Cruise Line International Association, whose "facts" are usually dubious, but from highly trained health care professionals. The medical and hygiene experts covertly evaluated the thoroughness of disinfection cleaning on fifty-six (56) cruise ships over the last three years

The professionals (Philip C. Carling, Lou Ann Bruno‐Murtha, and Jeffrey K. Griffiths) are tops in their fields.  They are from highly respected universities, including Boston University School of Medicine, Harvard Medical School, and Tufts University Schools of Medicine, Nutrition, and Engineering.

These experts secretly tested whether objects with high potential for fecal contamination, such as toilet seats in cruise ship public restrooms, could be a cause of norovirus breakouts.

The experts' objective tests revealed that only 37% of selected toilet area objects on cruise ships were cleaned on a daily basis. Such low scores may explain why certain cruise ships are prone to infect passengers with norovirus. 

The experts' recommendation?  "Enhanced public restroom cleaning." 

Let's keep it simple, stop blaming the passengers - and clean the damn toilets!
