Cruise Law News : Maritime Lawyer & Attorney : James M. Walker : Walker & O'Neill Law Firm : Admiralty Law, Cruise Ship Accidents & Injuries

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 about 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 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 be 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.

The Centers for Disease Control ("CDC") report that 118 of the 2,730 passengers aboard the Celebrity Solstice cruise ship have reported to the ship's medical facility with vomiting, diarrhea and other symptoms of gastrointestinal illness.

The Solstice is currently on a 14 day cruise and will return to Fort Lauderdale on December 11, 2011.

Pursuant to the CDC Vessel Sanitation Program, environmental health officers and an epidemiologist will board the cruise ship, once it returns to Fort Lauderdale tomorrow, in order assess the outbreak and the cruise line's response activities.

It has been our experience over the years that the "official" CDC numbers of ill passengers and crewmembers is usually less than the true number of those afflicted with viral illnesses.  This is because 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.  Often, sick crewmembers are pressed to work notwithstanding their sicknesses.  

We wrote about the problem of under reporting last year when the Celebrity Mercury experienced a prolonged outbreak of norovirus: Is Celebrity Cruises Under-Reporting Sicknesses to the CDC?

This is not the first time the Solstice has experienced an outbreak this year.  In January and February, there were norovirus outbreaks on the Solstice with one passenger dying due to exposure to the virus. 

Celebrity Cruises has experienced other bouts of widespread illnesses in 2011.  Over 100 passengers became sick on the Millennium in May of this year. 

Not all gastrointestinal outbreaks are documented with the CDC.  The cruise lines do not have to report the outbreaks when the cruise ship does not call on a U.S. port.  In September, norovirus broke out on Celebrity's Eclipse sailing out of Southampton, England.  You will find no mention of it in the official CDC database.

Earlier this week, we discussed Is there a Cure for the Cruise Ship Virus?

If you were on the Solstice and have something to add to this story, please leave a comment below.  Was the sickness more widespread than reported?  How did the cruise line handle the situation?

Afraid of your cruise vacation ruined by a nasty bout of diarrhea and vomiting?

There may be hope for you.   

WebMD and a few other medical journals report that there have been promising results from the tests of an experimental vaccine designed to prevent infection and symptoms associated with  norovirus.

WebMD explains that researchers sprayed the experimental vaccine in the noses of 47 volunteers. They also sprayed a "placebo vaccine in the noses of 43 other volunteers."  The study participants all swallowed a large dose of the norovirus (yuck).

About two-thirds of those who got the placebo vaccine developed gastrointestinal symptoms such as diarrhea and vomiting.  However, only a third of the participants who received the real vaccine developed  symptoms.

The researcher behind the experiment, Dr. Robert Atmar, a professor of medicine and molecular virology at the Baylor College of Medicine, said that the results are very promising, but it will be a few more years of research before the vaccine can be offered to the public.

Although commonly referred to as the "cruise ship virus," the virus also affects nursing homes, hospitals and restaurants.   Over the years, the cruise industry's trade organization, Cruise Lines International Association ("CLIA"), has tried to disassociate itself from this nasty virus.  It often writes to newspapers complaining when norovirus is described in such nautical terms.

When nororvirus breaks out on a cruise ship, you will usually hear the cruise lines and pro-cruise line publications stating that the cruise ship has been subjected to "enhanced cleaning,' whatever that means.  Cruise Critic ran an article earlier this year with a title "Norovirus is NOT a 'Cruise Ship' Virus."   The article showed a couple of photographs of crewmembers spraying down tables, chairs and even the roulette wheel.  Many topical solutions sprayed like this are not effective in killing the virus.  If a towel is contaminated, the wiping down of everything in sight spreads the virus everywhere. 

You will never hear the cruise lines or industry publications mention that the norovirus may not be spread from person-to-person, but  have been transmitted by contaminated food or water.   

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."  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.

Whatever the source of the virus on cruise ships, it is encouraging that there are doctors researching a vaccine against this dreaded sickness.

The Southern Daily Echo newspaper in Southampton England is reporting that the Celebrity Eclipse cruise ship was delayed for “enhanced sanitation” after dozens of passengers returning to Southampton from a 11 night eastern Mediterranean cruise had been struck down by norovirus.

Sick passengers disembarking the cruise ship at the city's terminal reported seeing “people walking around in Ghostbusters suits” ready to disinfect the vessel and the terminal.

Cruise ship norovirus cases often take several sailings before the virus runs its course.  Perhaps the Eclipse needs a major cleaning and spray down.  But "enhanced cleaning" may or may not help, depending on whether the virus is passed hand-to-hand between crew and passengers or passenger to passenger - or is contained in contaminated food or water. 

If you were on the Eclipse, please leave a comment below about how the cruise line handled the situation.  We would be interested in hearing from passengers on the ship now whether additional passengers have been sickened or whether everyone is well and enjoying the cruise.

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. 

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 . . .

For those of you who read Cruise Law News know that I report regularly on the numerous norovirus cases which plague the cruise industry.  I am rather fascinated by the cruise lines' PR departments which always blame norovirus outbreaks on the passengers for bringing the virus aboard, rather than contaminated food and water which infect the passengers.

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."  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.

The question I have always wondered is how does the water become infected with norovirus?

So I was rather exciting after receiving an email yesterday from a kindred spirit from Britain, Mr. Pat Gardiner, who combines a maritime background with a keen interest in zoonotic disease.  Mr. Gardiner referred me to a recent study from Swedish researchers finding a direct correlation between pig effluent and water sources contaminated with norovirus.  Mr. Gardiner agreed to be a guest blogger, and for that my little blog is richer. 

Be sure to read Mr. Gardiner's rather fascinating background at the end of the article.    

Norovirus - Something in the Water - By Pat Gardiner:  

The constant outbreaks of Norovirus on cruise ships are bringing a powerful industry to its knees, quite aside from the distress and risk to the passengers.  Yet, new evidence yesterday suggests the problem may be ashore and entering the ship with the water supply.

Eureka moments do not come from thin air.  They come from relevant, sometimes diverse experience in the right place at the right time.  Few people can have had the delights of a career in Britain’s most successful seaports, retiring early to raise livestock in an area plagued by constant animal epidemics.

The writer has had a ten-year battle with the British authorities over the appalling handling of animal disease spreading to the human population.  Years ago, he noticed an apparent link between the locations of severe animal disease and the schedules of cruise ships. The ships were calling at ports worldwide in areas where pig disease was rife.

Norovirus is a disease shared between humans and pigs.

Few passengers, once on board, give a thought to the source of the water they use to wash and brush their teeth.  Every cruise ship fills with water, before, during and after every voyage at pretty well every port of call. That water comes from the public supply.

So a ship leaving the UK for a cruise to the Norwegian Fjords would take water from the same country as the passengers embarking – Harwich for example. Vessels calling at Harwich were some of the first to encounter norovirus at the same time as the pigs in the area were getting ill. Now, even ferries from the Scottish mainland to the Scottish islands are becoming infected.

For years, the mechanism by which the norovirus reached the ship baffled the writer.

Smuggling of live pigs and bacon sandwiches on board seemed unlikely for passengers bent on a holiday of glamour and luxury.

Then yesterday the ultra clean Swedes provided the missing link. They found norovirus in the sludge intrinsic to their public water system.

We know that pig effluent can contaminate the surface water and the water supply. Incidents are frequent despite the best efforts of everyone. We know that pigs can carry norovirus.  

We also know that, like everyone else, the Swedes have had outbreaks of various pig diseases.

If the water authority do not look for norovirus or do not detect it, the pathogen will be pumped straight into the cruise ship: directly into the ideal environment for spread to a usually elderly population in an enclosed area.

Any vessel calling at, or sailing via, ports in pig farming country is at risk.

It would be grand to think that the writer has repaid the debt of a satisfying career in shipping by helping to solve one of the most damaging problems imaginable, both to shipping and their customers.

Testing the water is cheap and easy, and the ship owners can do it tomorrow.

About Pat Gardiner:

Mr. Gardiner was too modest to provide me with a biography, but I managed to piece together his background from newspapers and information on line. 

Mr Gardiner started out in the maritime shipping business in the 1960's, working for Blue Star Line in Britain.  He rose to the top of the ship and line agencies in Britain's premier port of Felixstowe.  He has enjoyed a long standing relationship with the U.S., which includes working with what is now the U.S. Sealift Command. He managed his own companies (which acted as agent for U.S. Line among others).  He is a well known figure in the U.K. port and shipping business, and also wrote for newspapers about the shipping and port business.  He twice sold his group of successful shipping and freight businesses, and retired from the maritime freight business while he was still in his forties.   

After his retirement, Mr. Gardiner developed an interest in animal health and zoonotic disease.  In the process, he developed an appropriate distrust of the U.K. veterinary services.

He is the author of two blogs - Animal-Epidemics and  Go Self Sufficient.

Mr. Gardiner is a pancreatic cancer survivor.  He also survived a unsuccessful campaign to ruin his reputation by members of the pig farming and vet industries. 

In 2005, Mr. Gardiner drove across the U.S. in 2005 with his wife.  They are pictured above at my favorite vacation destination, a U.S. national park (Grand Canyon).  Mr. Gardiner can be reached at: patgardiner@btinternet.com 

Additional information:

The "Gardiner Hypothesis:"  Mutated Circovirus in pigs, the consequences of being treated with heavy use of antibiotics, is followed by MRSA in pigs and then MRSA and C.Diff epidemics take off in humans. A circovirus mutation in Britain in 1999 was covered up. The resulting epidemics spread first around the UK, then to Canada and from there, most recently, to the United States.

Learn a new word:

"Zoonotic diseases" - diseases caused by infectious agents that can be transmitted between, or are shared by, animals and humans.

A reader of our blog informs us that Royal Caribbean's Jewel of the Seas continues to infect cruise passengers with norovirus. 

The reader referred us to the Harwich and Manningtree Standard and Daily Gazette newspapers in Norwich U.K. which report that Royal Caribbean passengers continue to be struck by a highly-contagious virus for the second time in a month. The cruise line again delayed the departure a few hours yesterday so that they crew could try some extra cleaning to deal with the problem.

The reader commented:

"Obviously the last attempt didn't work, so why should this? I would have expected that by now, the source and specific nature of the virus would have been found, thus allowing effective treatment to be carried out before the ship sails. However, since I have not heard otherwise, I assume it has sailed again last evening, with a new set of unsuspecting guests . . .  How can the port authority in Harwich allow this to happen?"

Royal Caribbean's PR people crafted the following statement: "At Royal Caribbean International, we have high health standards for all our guests and crew."

We reported on the last norovirus outbreak on the Jewel of the Seas - Norovirus On Royal Caribbean's Jewel Of The Seas?   45 passengers commented on the story and described poor food handling, cleaning, and medical procedures on the Royal Caribbean cruise ship.  

Have you sailed on the Jewel of the Seas recently?  How is the cruise line handling the situation?

Cruises.co.uk reports today that norovirus has broken out aboard Royal Caribbean's Jewel of the Seas cruise ship. 

The website reports that passengers due to sail on June 12,  2010 have been informed to arrive late as embarkation will start to take place from 4:30pm.  The cruise ship will apparently undergo what the cruise line calls an "enhanced sanitizing" on Saturday.

The Jewel of the Seas had widespread sickness (diarrhea and vomiting) last March, but the Center for Disease Control (CDC) could not determine the type of pathogen.  You can read the CDC analysis here.

The CDC database for cruise ship norovirus outbreaks is here.

For prior blog articles about cruise ship norovirus, read them here. 

Royal Caribbean's cruise ship, the Constellation, operated by its subsidiary Celebrity Cruises also sickened passengers and crew just two weeks ago.  164 passengers and 29 crewmembers developed a norovirus infection, according to Cruise.co.uk.  You will not find this officially reported to the CDC because cruise ships are not required to report outbreaks of sicknesses when the cruise ship does not call on a U.S. port. 

Royal Caribbean's PR crisis manager Cynthia Martinez issued a statement that the Constellation would be delayed so that the ship would undergo a "thorough cleaning and sanitizing." 

This sounds good but what does this mean?   As we mentioned 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." 

So how does a cruise ship go about a "thorough cleaning" when the cruise lines has not determined whether the source of the norovirus is infected food or water?  How do you perform an "enhanced sanitizing" of food or water?

Royal Caribbean's PR department refused to respond to a request for a statement or a comment on the latest sicknesses to Cruise Law News (CLN). 

If you are disembarking from the Jewel of the Seas or the Constellation, please leave a note below and provide us with your thoughts on how the cruise line handled the outbreak.  

June 12th Update:

Newspapers in Harwich are reporting that 398 passengers and 30 crew fell ill with norovirus while on board the Jewel of the Seas.  A company PR release states that boarding today will be delayed until 3:00 p.m. for what the cruise line states is "extensive," "thorough" and "enhanced" sanitizing.  But health officials have not identified the source of the norovirus as either contaminated food or water, unsanitary crew members, or infected passengers.  So what will additional cleaning for 2 or 3 hours accomplish?

Passengers are beginning to leave interesting comments below, pointing out that the method of serving passengers is likely causing the norovirus to spread . . .   

June 26, 2010 Update:

Royal Caribbean is violating U.K. law by sailing without completely sanitizing the contaminated cruise ship.  Some very astute readers are leaving insightful comments below, regarding the potential causes of the virus and the cruise line's shortcommings.  Be sure to read the comments at the bottom.

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 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!

At 8:00 p.m. this evening, Celebrity Cruises' Mercury cruise ship will sail for an eight day cruise to the Caribbean.

The Mercury has been called the "sickest sea at sea."  Even ABC's Good Morning America posed the question: Celebrity Mercury - Sickest Ship At Sea - Can Cruise Ship Be Cured? 

Local South Carolina ABC affiliate WCIV News - 4 is optimistic that the cruise ship has been thoroughly cleaned over the past 72 hours after the Centers for Disease Control (CDC) issued a rare "no-sail" advisory.  The ABC affiliate reports that "officials are now confident the ship is safe."

But I would not be so sure.  Gastro-intestinal illnesses can be caused by contaminated food or water, from fecal-oral transmission from crew member to passenger, or from sick passengers who come aboard and infect others.

And the CDC has not determined the cause of the last sickness outbreak.  The CDC report for the Celebrity Mercury's March 8th -19th sailing indicates that the "causative" agent for the widespread illnesses is "unknown."

Not sure I would set sail on a "sick" cruise ship where the CDC can't exclude contaminated food or water or ill crew members as the causes. 

Let's cross our fingers and hope another round of passengers don't find themselves confined to their cabins.  

March 22, 2010 Update:

According to USA Today, only 1,076 passengers are cruising on the Mercury (which is about 60% full).  Around 800 passengers canceled and obtained what is described as a full refund.

• Comments (3)

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."

The Celebrity Mercury cruise ship returned to port in Charleston South Carolina today with over 400 sick passengers.  The Centers for Disease Control (CDC) reports that 406 of the 1829 passengers (22.1%) have reported fever, vomiting, and/or diarrhea.

Unlike the last two cruises where the CDC determined that norovirus caused the outbreak, the CDC has not yet determined the cause of the outbreak.  This is probably one of the reasons that the CDC issues a "no travel" advisory for the sick cruise ship.

The traveling public is faced with a cruise line who blames passengers for not washing their hands - the CDC who does not know what the pathogen is or where it's coming from - and the ugly likelihood that the vessel's food, water, crew or public surfaces could be contaminated.

We have been inundated with calls and emails from concerned Americans who are scheduled to travel on the Mercury over the course of the next several months.  We also have heard from crew members, including some crew members who complain that although they are sick they are required to keep working.  Some of the work includes changing linens, serving food and delivering ice.  Very disturbing information. 

There is a lot of pressure on crew members to keep outbreaks secret.  We recently ran across a blog from a former crew member who wrote:

I worked on a cruise ship at the beginning of 2001 and we had a lengthy norovirus outbreak - interestingly, the ship did not make the CDC list for that year. Perhaps because we were far away in South America? Or perhaps it was because we were instructed to deny, deny, deny when any passenger asked: No sir, you're mistaken - the dining rooms are all closed because all the guests are off on tour...not sick in their beds along with half the staff. (Yeah, I was never able to look anyone in the eye and say that.) I never got it, thank God .  .  . "

Here is a recent video from the AP:

The Centers for Disease Control (CDC) has issued a rare no-sail advisory for Celebrity Cruises' Mercury cruise ship.  The CDC has instructed Celebrity not to sail the sick cruise ship until Sunday in order to permit its inspectors to investigate the ongoing outbreaks of gastrointestinal illness. 

Over the course of the last month, hundreds of passengers have become sick on the Mercury over the course of its last three sailings. 

According to CNN, members of the CDC's Vessel Sanitation Program (VSP) boarded the cruise ship looking for causes of the latest wave of illness.

Although the CDC determined that norovirus was the cause of the outbreaks for the first two sailings, the CDC could not determine the type of pathogen for the latest outbreak on the Mercury.

A no-sail advisory is an extreme step.  Its like a city inspector shutting down a dirty restaurant for code violations which pose a health hazard to the city residents. 

The Mercury has been a sailing nightmare for the past month.  First, a half dozen crew members were sickened in what the cruise line thought was carbon monoxide poisoning -  Carbon Monoxide Poisoning Reported Aboard Celebrity's Mercury Cruise Ship - when the cruise ship returned to port in Baltimore.  After the ship was re-positioned to South Carolina, all cruises have been plagued by what many call "cruise ship sickness."

The Mercury is an old ship and Royal Caribbean / Celebrity will be selling it later this year. 

For a chronology of the diseased ship, read our blogs over the past month regarding the Mercury.

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.

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.”

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

• Comments (9)

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 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?  

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.

A headline in the NoroBlog intrigued me - "Cruise Ships Causing Norovirus Outbreaks in Ports?" - indicating that norovirus is "often associated with cruise ship sickness."  The article also raises the question whether cruise ships can infect the local port communities. 

The cruise industry's PR people have been fighting the connection between norovirus and "cruise ship sickness" for many years.

Last week the cruise industry's trade organization, Cruise Line International Association (CLIA), wrote a letter to the Daytona Beach News Journal complaining that a writer made a connection between the virus and cruise ships and concluded that this is an illness that happens "often" on cruise ships.

CLIA's letter to the editor stated: "the overwhelming majority of norovirus outbreaks take place at land-based locations, such as schools, day care centers, hospitals and nursing homes."  The one comment to the letter, from a passenger on the norovirus infected Queen Victoria cruise ships, dismissed the letter as "more cover-up from the cruise spokes people."

CLIA has made the "its-a-lot-worse-ashore" argument before.  But arguing that it has a better record than day care centers and nursing homes seems counter-productive to the cruise line's image.  Of course day care centers with a million kids who have not mastered the art of going to the toilet and washing their hands and then wipe their runny noses all over the toys are going to be a hotbed of viruses.  And anyone entering a nursing home filled with incontinent geriatrics can instantly smell feces entering the facility.

The Food Poison Journal (affiliated with the Noroblog) reports that "outbreaks of gastrointestinal illness, and norovirus in particular, are not new to the cruise industry.  In fact, the phenomenon prompted the CDC to create and oversee a "vessel sanitation program (VSP)." 

Arguing against the label "cruise ship sickness" is a waste of time.  The real debate should be whether sick cruise ships pose a health hazard to the local port communities.

In the past six weeks, the United States considered blocking the arrival of the Queen Victoria because of a norovirus outbreak - U.S. to Block Arrival of Queen Victoria After Norovirus Outbreak?  - and a week earlier the U.K. considered impounding the Balmoral cruise ship because of a similar outbreak -  "Cursed Cruise Ship" Balmoral At Risk of Being Impounded As Hundreds More Suffer Vomiting Bug.

The South Carolina Post and Courier ran an interesting article "Norovirus Confirmed Aboard Mercury" which reported on the concern that the Celebrity Mercury cruise ship - with over 400 norovirus infected passengers - could infect people living in Charleston.  

The newspaper reports that Katie Zimmerman, a project manager with the Coastal Conservation League, received frantic calls and e-mails from residents concerned not only about infected passengers entering the city but also about trash from the ship entering local waters.

Cruise ships like the Mercury can dump completely untreated sewage 12 miles offshore.  Although the article concludes that waste from the Mercury poses no risk to marine life or people who eat local seafood, there is a risk of contaminated water infecting shellfish which filter-feed. 

In this day and age, it is barbaric to think that hundreds of CLIA cruise ships routinely dump human waste into the sea.  Cruise lines dump waste because they register their cruise ships outside of U.S. jurisdiction in places like Liberia and Panama which don't care what the cruise lines do. 

The thought of a cruise ship like the Mercury dumping hundreds of thousands of gallons of norovirus infected feces just 12 miles offshore South Carolina is particularly disgusting. 

Even the worst run child care facilities and nursing homes don't do that.
