The events listed have been reported in the public domain or to cruisejunkie by passengers or crew members onboard.  The list is by no means comprehensive.  For that reason it is necessary to be cautious in drawing conclusions from the potentially limited data.  Keep in mind that some companies may be more transparent than others about things that go wrong; conversely, some companies may be better at concealing events and thereby project an appearance that is inaccurate.  With that said, the following list is still interesting, as are the patterns when viewed separately by ship.

December 4 Amsterdam The CDC reports 64of 791 passengers (8.1%) and 3 of 610 crew (0.49%) have reported ill with gastrointestinal illness. Two CDC Vessel Sanitation Program environmental health officers and an epidemioligist will board the ship on arrival in San Diego on December 5 to conduct an environmental health assessment and evaluate the outbreak and response activities. The ship was on a 24 day cruise. The ship will require a delayed debarkation on Wednesday. Embarkation will begin after 2PM. UPDATE Dec 7: The number ill is now 85 of 791 pax (10.275%) and 6 of 610 crew (0.98%)
September 19 Veendam CBC reports the ship arrived in Sydney carrying some sick passengers. Erik Elvejord, spokesman for the cruise line, said 20 passengers have gastrointestinal illness. He said the cruise line has dealt with similar levels of sickness before. Holland America lines has notified Health Canada. The ship heads to Halifax after leaving Sydney.
February 6 Rotterdam From a passenger: We returned Feb 3 from a 30 day Hawaii and S. Pacific Cruise on the Rotterdam. We had a code red situation because of GI for 8 of the 30 days and nearly everyone else came down with the respiratory colds and or severe cough.  Luckily my wife and I did not get GI but we both got the severe respiratory illness and my wife is still undergoing medical care.  Everyone aboard referred to it as the Rotterdam cough.  Have no idea how many passengers and cruise had the GI problem but the last day of the cruise I spoke with 4 people I had not met previously and half had the problem earlier.  One said she developed the illness on Day 2 of the cruise. We were not notified of the illness until many many days later.  Passengers did not cooperate with the health instructions given by the officers and strolled into the food areas refusing to use the sanitizers.  HAL needs to station people of authority at the entrance to these areas and deny admission to people how refuse to sanitize.  
January 4 Maasdam The CDC reports reports 56 of 1255 passengers (4.46%) and 6 of 573 crew (1.05%) have reported ill with gastrointestinal illness. A CDC Vessel Sanitation Program environmental health officer and an epidemiologist boarded the ship on arrival in Ft. Lauderdale, FL on January 2, 2012 to conduct targeted environmental health and epidemiologic assessments and evaluate the outbreak and response activities. Ship crew conducted intensified cleaning and disinfection of staterooms occupied by those who reported their GI illness to the infirmary. Stool specimens were sent to the CDC lab for testing. The ship is on a 10 day cruise ending January 2nd. From a passenger: Two or three days into the voyage, the Captain came on the PA to announce the problem.  He said it came from European passengers.  They closed buffet lines and the crew had to serve you; they removed salt/pepper shakers from the dining room; they took rolls away and served bread at dinner with tongs, and closed the hot tub.  In addition, in the evenings, we saw our cabin steward and assistant washing down all of the cabin corridors (even the ceiling) with disinfectant.  In addition, when passengers became ill, they were confined to their cabin and the stewards were not allowed to clean.  When "quarantine" was over, crew members with masks went to the "contaminated" cabins and cleaned under supervision.  The Captain announced the numbers ill and daily progress against the illness.  The largest number announced was about 25.  We had friends on the next voyage and learned that embarkation was delayed as they continued to try to rid the ship of the GI virus.  HAL also had people stationed at each entrance to the dining areas providing hand sanitizer to all passengers to try to control the outbreak.  
December 22 Maasdam From as Passenger: I just got off the Masdam yesterday after an 11 day cruise. They said there was a noro outbreak on board but I did not see any evidence of this. No gloves or not being able to self serve from the buffet. What I did notice was that after 3 days many many people were sick with a head cold symptoms, caughing, sore throats, ear aches etc. This continued to grow by the days. My wife and myself eventually got it too. Also at the terminal in St. Kitts 2 people fell in the same spot and suffered broken arms. We had 1 bright star emergency in St lucia and a passenger was rushed to the hospital by ambulance at docking.
December 16 Ryndam The CDC reports reports 69 of 1298 passengers (5.32%) and 6 of 574 crew (1.05%) have reported ill with gastrointestinal illness. A CDC Vessel Sanitation Program environmental health officer and an epidemiologist will board the ship on arrival in Tampa on December 18, 2011, to conduct a targeted environmental health assessment and evaluate the outbreak and response activities. The ship is on a 7 day cruise ending December 18th.
November 22 Veendam Terra News (Brazil) reports the ship arrive on Tuesday morning at Pier Maua in the center of Rio de Janeiro, and, according to initial information from the Municipal Health Department, some of the transatlantic passenger suffering a crisis of gastroenteritis. An American tourist died. The fatality was identified as Dorothy Mizzen Philips, 61. The cause of death has not been confirmed. Agents of the Federal Police (PF), with the support of city police officers were at Pier Maua early on Tuesday to receive the ship's passengers. Those who are feeling sick will be taken to the post of ANVISA at the International Airport Antonio Carlos Jobim (Galleon), on Governor's Island, north of the city.The New York Post subsequently reported at least 72 passengers and seven crew members were affected by an unspecified ailment on the journey from Chile. Anvisa officials who boarded the ship when it docked in Rio Tuesday found only two people still showed symptoms of intestinal discomfort, Azaro said. The Vancouver Sun subsequently reports that 79 passengers and 7 crew member reportedly became ill with gastrointestinal illness.
November 18 Ryndam The CDC reports reports 148 of 1188 passengers (12.46%) and 11 of 732 crew (1.92%) have reported ill with gastrointestinal illness. A CDC Vessel Sanitation Program environmental health officers and two epidemiologists boarded the ship on arrival in HAL's private island in the Bahamas on November 18, 2011, to conduct a comprehensive environmental health assessment and evaluate the outbreak and response activities. The ship is on a 14 day cruise ending November 20th.
6.11.10 Nieuw Amsterdam The CDC reports 123 of 2027 passengers (6.06%) and 4 of 878 crew (0.46%) have reported ill with gastrointestinal illness. The ship arrives in Fort Lauderdale November 7th following a 20 day transatlantic cruise. UPDATE: The final numbers are 134 (6.61%) passengers and 6 (0.69%) crew.
6.5.10 Zuiderdam The CDC reports that 73 of 1846 passengers (3.95%) and 5 of 793 crew (0.63%) have reported ill with gastrointestinal illness. The ship arrives at Vancouver May 8th from a 19 day cruise.
7.3.10 Rotterdam From a passenger: The ship is currently "Code Red" suspected to be the norovirus. Embarkation today will be delayed approximately 2 hours while the ship is being cleaned by crew and contracted union janitoial personnel. Complimentary shuttle busses have been chartered to take guests to nearby Seaport Village.
3.3.10 Maasdam The CDC reports that 168 of 1211 passengers (13.87%) and 19 of 559 crew (3.40%) have reported ill with gastrointestinal illness. The ship arrives at Fort Lauderdale March 5th from a 14 day cruise.
23.2.10 Maasdam From a passenger: Maasdam has just gone into code red with a few cases of GI on board. So far don't know the numbers but to prevent spreading it further and developing into a major outbreak food and water is being served to us, no salt and pepper shakers on tables etc. Only 2 days into it but hopefully it will be over with soon!
14.1.10 Noordam A passenger wrote to say the 10 day cruise from Fort Lauderdale to  the Caribbean (January 04-14 2010) had a norovirus outbreak on the  3rd day of the 10 day cruise and it ended on the last full day of the cruise. It was subsequently learned that the number of people infected was 36-38, so below the 3% threshold to be considered an outbreak.  The cruise left Fort Lauderdale 01/04/10 and the outbreak started 01/07/10 and ended 01/13/10.  My cynical self became very suspicious when there was no additional disinfecting practices observed.
14.1.10 Amsterdam The CDC today reported the following illness outbreak last month: The ship reported 8 of 610 (1.31%) crew and 56 of 1317 (4.25%) passengers had reported ill with gastrointestinal illness on a 21 day cruise ending December 23.
22.10.09 Noordam Gibraltar News from Panorama reports the ship sailed into Gibraltar yesterday with food poisoning onboard. The bug caused a stir with some tour guides and coach drivers, as the word got round of what some were saying was an outbreak of gastro-enteritis. A number of drivers/guides refused to work given the nature of the outbreak. What is regarded as surprising is that passengers were allowed to come ashore, when in other ports it is sometimes the case that passengers are barred to avoid the spread of a bug onboard the ship. Questioned by PANORAMA, ship agents Turner & Co confirmed that there had been "some food poisoning onboard, but contained, and confined to one part of the ship." UPDATE: The CDC reports 16 of 784 (2.04%) crew and 140 of 1826 (7.67%) passengers had reported ill with gastrointestinal illness on a 15 day cruise ending November 1 in Ft. Lauderdale.
30.5.09 Amsterdam The ship reported 8 of 587 (1.37%) crew and 101 of 1546 (6.53%) passengers had reported ill with gastrointestinal illness on a 7 day cruise ending today.
23.4.09 Amsterdam The ship reported 19 of 600 (3.17%) crew and 119 of 1318 (9.03%) passengers had reported ill with gastrointestinal illness on a 22 day Panama Canal cruise ending in Vancouver April 24.UPDATE April 28: CDC has revised the numbers to 25 crew (4.17%) and 135 passengers (10.24%). The cause of the illness is Cyclospora cayetanensis.
24.3.09 Westerdam From a passenger: We just returned from a seven day cruise on the Holland Westerdam, March 15 thru March 22 2009. When we boarded the ship, we noticed that the crew was passing out the anti bacterial liquid on every floor. Three days in the cruise we noticed the employees were thinner than normal. Five days and the Captain of the ship announced that there was indeed some sick crew and passengers and they were trying to contain the GI Virus. We could not even get our own coffee or sugar. No salt and pepper shakers on table. It was a terrible cruise. I would not recommend it to anyone.
Oosterdam KFMB-TV in San Diego reports 84 passengers have reported ill with gastrointestinal illness, likely caused by norovirus. The ship returns to San Diego tomorrow and acccording to the cruise line will be sanitized. Update March 2: eFluxMedia reports the numbers are now 106 passengers and 4 crew reporting ill. NOTE: Is it a coincidence that this cruise began the day after the Zaandam cruise (below) ended or is it possible a crew member from Zaandam brought the illness with him/her onto Oosterdam? UPDATE: CDC reports the numbers ill at 110 of 1840 (5.98%) passengers and 10 of 786 (1.27%) crewmembers.
Zaandam From a reader: My mother and her husband are sailing aboard Holland America’s Zaandam, which departed San Diego for Hawaii on February 5. Several days ago, she called, saying passengers were reporting bouts of diarrhea and vomiting. Sick passengers were being isolated in their rooms for 36-48 hours. According to her, self-serve buffets had been converted to staff-served and regular cleaning crews had been replaced with special personnel. Extra hand sanitizer had been placed in her room. Tonight, she called again, saying she and her husband had been sick with diarrhea, vomiting, fever and a neck rash for four days. UPDATE: The CDC reports 21 of 590 (3.6%) crew and 74 of 1408 (5.3) passengers have reported ill. The cruise ends in San Diego on February 20.
Maasdam From a Passenger: There was an outbreak of what the cruise ship's medical staff was diagnosing as a gastrointestinal virus on the January 2-9, 2009 sailing.  Five of our family's seven members on board, in three seperate cabins, were affected and spent multiple days in isolation. I was told by my treating nurse that he was brought over from the Noordam to assist due to the number of sick passengers. I have not seen any reports of this anywhere yet. The passenger also said he was told that more than 60 passsengers had been treated for gastrointestinal illness. The CDC subsequently reported 8 of 561 (1.4%) crew and 79 of 1402 (5.6%) passengers had reported ill with gastrointestinal illness.
Veendam FROM A PASSENGER: We were on Westerdam on a back-to-back cruise from Nov 30th to Dec 14th.  On Dec 12th before we disembark at our port of call Costa Maya our Captain mentioned over the PA that we should not mix with the other people on the ship dock beside us (which was Veendam) because of an outbreak of that "ship flu." He said about 40 pax were ill.
Zuiderdam From a passenger: Doing a 17 day cruise from Venice to Ft. Lauderdale. Self service of all food stopped a week ago trying to contain spread of Norovirus. Few cases of Norovirus until yesterday when 20 new cases reported. Today another 35 reported and now have been informed that our stop at Half Moon Cay has been cancelled as they are worried about spread of Norovirus on the tenders to the island. We have been scheduled to stop at Nassau on Saturday November 8 instead. UPDATE November 6: CDC reports 14 of 794 (1.76%) crew and 224 of 1820 (12.31%) passengers had reported ill with gastrointestinal illness on this cruise ending November 9. Update November 10: CDC now reports 17 of 794 crew (2.14%)  and 261 of 1820 passengers (14.34%).
Volendam The Marlborough Express (New Zealand) reports a norovirus outbreak (the ship is on Code Red) aboard the ship that prevented visitors while it was in Picton. The ship was to host a fundraising luncheon for the Marlborough Community Hospice but it was postponed. The Otaga Daily Times reports Octiober 31 that the number reported ill at 60. UPDATE: The ship's "welcome to Sydney (Australia) was reportedly cancelled because of norovirus onboard.
The Anchorage Daily News reports that an unnamed Holland America ship has had an elevated number of illnesses. It states that rumors about a norovirus outbreak followed the ship from port to port, prompting media inquiries. The ship had about 20 sick passengers early in its cruise when it was in Haines. It went to Juneau and Sitka before pulling into Seward (the end of a seven-day cruise). According to one source, the ship has been in Code Red due to the Norwalk Virius since last Thursday. The Veendam is doing Alaska (Vancouver to Seward 7 days, and Seward to Vancouver 7 days). Guests sailing for 14 days were all placed in quarintine for 24 hours last Friday after being plied with free tours in Seward since extra crew were flown in to clean the ship. All staff were present in the Lido restaurant to help serve guests. No salt and pepper shakers, no self serve coffee stations and activities cancelled. Over 100 guests were sick and approximately 20 crew affected. The outbreak was subsequently reported by the Centers for Disease Control -- it reports 112 of 1313 passengers (8.53%) and 12 of 556 crew (2.16%) were ill.
The ship reported 13 of 611 (2.13%) crew and 100 of 1428 (7.00%) passengers had reported ill on a 15 day Hawaii cruise that began March 19 in San Diego and which disembarked April 3.
Oosterdam From a passenger: We just returned from a 7 day Baja cruise.  Two days into the cruise my fiance became very ill and was quarantined to the cabin for 48+ hours. It was the virus. Naturally this ruined the cruise for us which was an Air America  Progressive Radio cruise, with 400 others. I never could find out how many others were ill, but I believe several. We were offered $200 in ship credit for this disaster, which we refused, going all the way to the Hotel Manager. There were inadequate services in place to deal with this quarantine and I was forced to carry meal trays and clean the bathroom! Regular stewards were not allowed to attend us.
Ryndam The ship reported 8 of 556 (1.44%) crew and 113 of 1226 (9.22%) passengers had reported ill on a 108 day Mexican Riviera cruise that began February 15 in San Diego and which disembarked February 25.
Noordam The ship reported 12 of 816 (1.47%) crew and 103 of 1980 (5.2%) passengers had reported ill on a Southern/Eastern Caribbean cruise that began January 5 in New York City and which disembarked January 16.
Volendam The ship reported 7 of 608 (1.15%) crew and 85 of 1451 (5.86%) passengers had reported ill on a Southern/Western Caribbean cruise that began January 2 in Fort Lauderdale and which disembarked  January 12.

Zaandam The ship reported  9 of 616 (1.3%) crew and 91 of 1371  (6.64%) passengers had reported ill on a 15 day Hawaii Cricle cruise from San Diego.
The ship reported that 2 of 606 (0.33%) crew and 69 of 1427  (4.84%) passengers had reported ill on a 11 day Southern Caribbean cruise from Fort Lauderdale (12 - 22 April)
Ryndam A passenger reports that the Mexican Riviera cruise ending today had an illness outbreak.  Those arriving for the next cruise were given a letter at check in that described the situation and that gave the option of a full refund if they chose to not make the cruise.  The ship was under "condition Red" for the entire cruise, with required hand disinfection, crew serving all food at the Lido, all hot clubs closed, complete cleaning of the ship every day, no bread baskets on the tables, etc.
Statendam Passengers were advised by letter from the Captain that there was a highly contagious  virus aboard among crew and passengers.   The number affected by the illness and the precise nature is unknown.  The cruise began in Hong Kong on March 22 and ended in  Osaka April 5.  Given that no US ports were in the itinerary, the ship is not required to report the illness outbreak to the CDC.
March 15 Maasdam The ship reported that 5 (0.88%) crew and 43 (3.61%) passengers had reported ill on a 10 day cruise to/from Fort Lauderdale (5 - 15 March).
Ryndam The ship reported that 7 of 593 (1.18%) crew and 61 of 1209  (5.05% passengers had reported ill on a 10 day cruise from San Diego to the Mexican Riviera, return (3 - 13 March).
Ryndam On February 27 the ship reported that 17 of 579 (2.94%) crew and 116 of 1260  (9.21% passengers had reported ill on a 10 day cruise from San Diego to the Mexican Riviera, return (21 Feb - 3 March).  Updated numbers 3 March:  26 of 579 (4.49%) crew and 184 of 1260  (14.4%) passengers.

Westerdam The ship reported that 9 of 809 (1.11%) crew and 146 of 1790  (8.16%) passengers had reported ill on a 7 day Eastern Caribbean to/from Fort Lauderdale (4  - 11 Feb).  Symptons were consistent with gastrointestinal illness (e.g., norovirus).
Volendam The ship reported that 7 of 608 (1.15%) crew and 105 of 1385 (7.58%) passengers had reported ill on the  10 day Southern Caribbean cruise returning to Fort Lauderdale today.  Symptons were consistent with gastrointestinal illness (e.g., norovirus).
Rotterdam From a passenger, Santiago to Rio, 11-31 January:  We were asked to complete a health questionnaire prior to boarding.  I know of at least a dozen folks who were quarantined to their cabins with intestinal problems, but the really big problem was a cold like illness with an uncontrollable cough that seemed to affect almost half the passengers.  The medical center told everyone that inquired that they hadn't had any complaints!
Oosterdam CBS in San Diego reports an outbreak of gastrointestinal illness on the 7-day Mexican Riviera cruise ending today.  While the cruise line says there were 55 passengers and crew reporting ill, reports from passengers indicate the number was higher.  One says about room service, "So many people were sick, they stopped answering the phone."  Room service was taking as long as three hours for deliveries.
Noordam From a passenger:  We were on the 12/06 - 12/16/2006 NYC/Caribbean 10 day r/t, and about the 3rd day received a note in all our rooms of a norovirus outbreak slightly above the normal rate.  There were members of the crew holding giant squeeze bags of Purell at all the entrances to the Dining Rooms, and offering it to everyone who walked in.
Zaandam The ship reported that 4 of 617 (0.67%) crew and 64 of 1431 (14.47%) passengers had reported ill on the 26 November -11 December Hawaiian circle cruise from San Diego.   Symptons were consistent with gastrointestinal illness (e.g., norovirus)
Statendam From a passenger: We had an outbreak of norovirus on board -- at the completion of our cruise we were told we had to vacate our staterooms by 8:00 am so the ship could have a “deep sanitization” done.  We were told by our dining room head waiter that about 30-35 people had come down with it.
Oosterdam Messages from several passengers report there was a small outbreak on the Alaska cruise ending today in Seattle -- the numbers may have been less than 3% (i.e., less than 55).  According to one passenger: "...passengers and crew became sick (total of about 36 I heard) with a stomach virus. The ship began taking precautions against contamination beginning about Tuesday (salt and pepper shakers disappeared, some crew wore gloves and masks, they were spraying something around the ship, lots of Purell being offered, etc.), but other than warnings to wash your hands and not shake hands, Holland America did not tell us much of what was going on."
Ryndam On June 2, the ship reported that 5 of 574  (0.87%) crew and 64 of 1230 (5.2%) passengers were ill.  The predominant symptoms were vomiting and diarrhea.  The 7 day Alaska cruise ended in Vancouver on June 4.
Ryndam According to passengers, a "Code Red" was called the second night of the cruise due to gastro intestinal illness on board.  The Spa and the 2 public jacuzzi pools were closed, all meal service was conducted on a strictly controlled access basis - no self serve and staff wore vinyl gloves for practically all tasks.  The onboard shops didn't allow passengers to try on any necklaces, watches, or rings.  During the cruise, several more obvious crew members became ill - the Piano bar pianist, the Bingo caller/Asst cruise director.  While the Captain continued to reassure passengers that no actual problem existed, many passengers were  missing from dinner tables and quarantited to their cabins. One staff reported that 50 passengers had reported sick; a passenger heard that as many as 50 crew had become ill.  The CDC posted on their site June 7th (dated May 21) that 102 of 1279 (7.97%) passengers and 13 of 570 (2.28%) of crew.
Veendam On May 9, the ship reported that 8 of 556 (1.41%) crew and 67 of 1214 (5.52%) passengers were ill.  The predominant symptoms were vomiting and diarrhea.  The 17 day cruise arrived in San Diego, from where it left on April 22.
After an hour delay, passengers boarding for the transatlantic crossing from Rio de Janeiro to Lisbon were given a questionaire to fill in about health issues, told there had been a gastrointestinal illness outbreak on the last cruise, and given the option to cancel the cruise (this at the last minute, after having travelled to Rio). On the ship there was no self service at the Lido etc, not even for coffee; all hot tubs, the library etc. was closed; no shaking of hands, no salt and pepper, bread/butter  on the table etc., everything was provided by the crew. According to one passenger:  They were fumigating all the time, even in the middle of the night, when I woke up because of the noise the machine was making. When I opened my door I saw a man with a mask and tank, who stopped immediatly. The crew would not say how many persons were ill. On day 8, cruise passengers were told the outbreak was over and self service at the buffets etc. would start again. They kept spraying all through the end of the cruise, which sometimes hurt my eyes and made breathing a bit difficult during a short time. We heard about several people who had gone in quarantaine after reporting ill.  All in all the ship jandled the situation very well.
Statendam Several hundred passengers and crew took ill due to Norwalk virus on the cruise which began in Osaka on April 3 and ended today in Hong Kong. The ship had guests fill out a health questionnaire prior to embarking in Osaka, which was a sign of things to come. The illness broke out in code red by day 3 with 75 cases and spread like wildfire. Several hundred passengers were ill by the cruise end. This apparently has been on-going since February, according to the crew, but this breakout was the worst. The ship was being fumigated room by room and all facilities were closed down throughout the cruise due to cleaning and the spread of the illness.  Guests embarking on 4/17/06 were also filling out the same questionnaire and the vessel was to be in code red for at  least the first four days of the subsequent sailing.  According to a passenger on that cruise: There were many restrictions during the cruise. Regardless, many people were ill, although Holland America staff downplayed just how many. Infected people and their traveling companions were quarantined
to their cabins for the duration of their illness plus one day. Room service was to deliver meals, but they were hard to reach, probably due to all the calls they were receiving.
Amsterdam For the second cruise in a row the ship has reported an elevated number of passengers and crew with gastrointestinal illness.  On April 6, the ship’s medical staff reported that 8 of 605 (1.32%) crew and 76 of 1294 (5.87%) passengers were ill.  The 15-day Hawaiian cruise ended in San Diego on April 6.
Amsterdam On March 13, 2006, Holland America Cruise Line reported that an elevated number of Amsterdam passengers and crew were experiencing symptoms that were consistent with acute gastroenteritis. The predominant symptoms are diarrhea and vomiting.  On March 21, the ship’s medical staff reported that 8 of 606 (1.32%) crew and 142 of 1360 (10.44%) passengers were ill.   The ship returns to San Diego from a 15 day Hawaii cruise on March 22.
Volendam On March 13, 2006, Holland America Cruise Line reported that an elevated number of Volendam passengers and crew were experiencing symptoms that were consistent with acute gastroenteritis. The predominant symptoms are diarrhea and vomiting.  On March 21, the ship’s medical staff reported that 3 of 613 (0.49%) crew and 51 of 1412 (3.61%) passengers were ill.   The ship returned to Port Everglades March 17 from a 10 night Southern Caribbean cruise.
Zuiderdam Upon arrival onto the ship, passengers were given a notice that about 2% of the previous passengers and crew reported ill with norovirus-like symptoms (2% = 54 passengers and crew). Passengers were offered a full refund or to take the cruise.  According to one passenger, Holland America had "Purell" sanitizers EVERYWHERE. No touching of buffet tongs, no salt and pepper shakers, no jacuzzi, no sauna, no hand shaking, yada, yada. Daily announcements from the cruise director and Captain.  Some passengers reported illness. 
Rotterdam From a passenger:
I just completed a cruise on Holland America's Rotterdam (December 20 - January 11, ending in Valparaiso, Chile), and at least 125 passengers and crew were ill with norwalk-like virus symptoms (nausea, vomiting, diarrhea).  Although every possible measure was being taken to deal with it (daily announcements, memos, staff using gloves and disinfectants) -- it still was a very difficult situation.  One of our concerns was that the staff was told clearly not to discuss it, and/or to minimize the situation -- this resulted in a lot of mixed signals coming from the staff - those who were telling the truth, and those who were covering up the events. When a passenger died on board (apparently of natural causes, and not related to the epidemic), again, the attempt at cover-up was obvious.
Zuiderdam On day 3 of a 7 day cruise the ship reported that 94 of 1888 (4.98%) passengers and 27 of 814 (3.32%) crew had reported ill with symptoms consistent with norovirus.  The ship is due back in Fort Lauderdale on January 7.  Note: A passenger reported an outbreak at the end of the previous cruise.  Numbers were revised on January 6:  50 of 814 (6.14%) crew reported ill and a survey of passengers found that 155 of 1023 respondents (15.2%) reported they were also ill. 
From a passenger: 
By Sunday there were many quarantined passengers and we decided to disembark early.  The ship's guest relation supervisor said he booked us a flight out of St Thomas -- we arrived at airport to find out Holland America staff lied ....THE FLIGHT TICKETS WERE NEVER BOOKED.  The ship left us sick, dehydrated and stranded without a care.
Zuiderdam From a passenger:
On the last night/morning, many people were stricken with a gastrointestinal illness that caused diarrhea and vomiting. A great deal of vomit was on the stairs, elevator and other public areas by Friday morning.  I was one of the seemingly many people that fell sick, and had to endure an extremely difficult day of travel home to Canada.   Advice:
the cruise line may benefit from providing some sort of follow up information service when so many passengers become sick on their ship; they may also benefit from frequent changing of serving utensils in the buffet areas.
Statendam From a passenger:  We sailed from San Diego to Auckland Nov. 17/05 to Dec. 22/05.   There was an outbreak of GI illness involving at least 60 - 70 passengers and unknown number of crew.  My husband was very ill for 24 hours and nauseous for a week but they didn't count him as they said he wasn't sick enough.  Passengers who were treated had to pay large fees - they said the illness came on board with people who boarded in Peru.
Westerdam Reported by a passenger:  An outbreak Norwalk type flu on cruise returning to Fort Lauderale Nov 13.  Captain informed us that forty passengers involved and nine remained in stateroom as of Nov 12.  Precautionay measures were taken: no self service or articles on tables.

There was an outbreak of influenza and bronchitis on the cruise from Rio de Janeiro, Brazil to Valparaiso, Chile. It was very widespread, as it seemed that nearly everyone was coughing severely.  Nearly everyone we met on the ship was infected.  The doctor on the ship diagnosed me with “what everyone else has”, influenza/bronchitis, and the flu shot was ineffective against this flu.  I know of one hospitalization in Puerto Montt, and the person was left there.  I was given an antiviral med and Z-Pak antibiotic, as was nearly everyone that I talked to.  At no time during the cruise did the captain or any other crew member acknowledge that there was a problem, except the doctor.  Rumor has it that several people got off the ship in Buenos Aires with possible pneumonia.

Veendam A passenger reports there was an outbreak of norovirus on the cruise ending today.  The cast was unable to perform the last shows due to illness and the ship was on full scale control measures.  Guests were not allowed to touch any untensils, salt and pepper disappeared, and crew were constantly wiping down everything.  We had to vacate cabins early on arrival so they could "super-sanitize" the ship.  In sum, 70 of 1,236 passengers (5.66%) and 7 of 571 crew (1.23%) reported ill.

Despite promises onboard, the 82 and 95 year olds were not given necessary assistance by HAL once they left the ship (including having to carry their own luggage up stairs). They are awaiting reimbursement for out-of-pocket expenses that they were told were arranged to be paid in advance.
