According to the Centers for Disease Control and Prevention (CDC), 73 people have reported sick, with symptoms of vomiting and diarrhea, on Holland America’s Zaandam during a cruise through Alaska.

58 of all passengers (3.94% of 1,472) and 15 of all crew members (2.54% of 591) have reported ill to the ship infirmary during the cruise which started on June 18, 2018.  The HAL cruise ship stopped in Juneau yesterday and plans on additional stops in Alaska before returning to Seattle on July 2nd.

Several newspapers report that the outbreak is due to norovirus, although the CDC indicates that the HAL Zaandamcausative agent is currently “unknown.”

Holland America Line experienced 19 cases of GI sicknesses reported to the CDC since 2010. Only Princess Cruises suffered more norovirus/GI cases which were reported to the CDC during this time period. Last year, HAL suffered norovirus outbreaks on the Nieuw Amsterdam, and two outbreaks each on the Volendam and the Noordam.

Cruise ships on non-U.S. itineraries do not have to report GI outbreaks. We have previously mentioned gastrointestinal outbreaks during cruises which do not include a U.S. port, including an outbreak on the Veendam which sailed to a port in Greece last November.

Update: This afternoon I received the following email from a passenger:

“Your latest article about Holland America caught my attention.

I must admit that I am shocked that here on board there is nothing being done regarding standard sanitation before eating. On Princess there is always someone present to give you a plate after you wash your hands or use the sanitation lotion. Here on the Westerdam there is nothing being done.

I don’t see any passengers using any cleaning methods before eating. Therefore your article doesn’t surprise me. Carnival needs to use Princess as an example and get Holland America to improve. I hope this information helps and maybe something can change.

On another note, last week we were sailing in glacier Bay and all paper napkins and straws should be prohibited as they do on Princess but I caught Holland America using them and I quickly reported this to a ranger on board who was shocked.

From my point of view Holland America is lowering their standards and it’s a shame.”

Oceania RivieraYesterday we received information about the current cruise of the Oceania Rivieria which is sailing through the Caribbean (Miami March 20-April 3). "The captain came on the intercom yesterday informing the passengers that a large number of passengers had come down with flu like/gastrointestinal issues and the CDC had been informed. The ship ported at their first stop Santa Marta, Colombia as scheduled today."

The Centers for Disease Control and Prevention (CDC) has now officially reported the third norovirus outbreak on the cruise ship.  

The first recent outbreak was during the November 18 – December 2, 2015 sailing and involved 74 ill passengers. The second outbreak occurred during the  February 12-22, 2016 sailing which had to be ended early and involved at least 124 sick passengers. We wrote about how the crew members had to work overtime, often off the clock and without extra pay, to try and super-clean the cruise ship. 

This latest outbreak involves at least 52 passengers who are ill with norovirus. Zero crew members were reported ill during the current cruise.

Unfortunately, the under-staffed CDC never tries to conduct a meaningful epidemiology assessment to determine whether the outbreak can be traced to a particular type of food contamination, an ill food handler, poor cleaning of the ship or an ill passenger who brought the noro aboard the ship. 

Expect the number of affected passengers to increase during the cruise notwithstanding the extra hours spraying and wiping by the crew. 

So far this year, there have been 8 gastrointestinal outbreaks reported to the CDC by cruise ships calling on U.S ports.
