Cruise Ship Norovirus Outbreaks at 15 Year Low in 2017

Gastrointestinal illness outbreaks on cruise ships are at a 15 year low so far in 2017 with only two outbreak cases reported in the first four months of the year according to the Centers for Disease Control (CDC).

Out of those two outbreaks, only one has been confirmed as a norovirus outbreak (Coral Princess March 8 sailing). Even though norovirus has been unfairly given the description of the “cruise ship illness”, the number of outbreaks is at the lowest point since 2001. One important fact to keep in mind is that cruise capacity has more than doubled since the turn of the century. Nearly 25 million people will take a cruise in 2017 while just under 10 million took a cruise in 2001. This means that the percentage of outbreaks on cruises is at the lowest point since the CDC began publishing outbreaks in 1994.

Number of G.I. Outbreaks on cruise ships through the first four months of the year since 2000:

Why does it seem to always make the news when a cruise does have an outbreak?  The cruise industry is required to report to the CDC anytime the illness count exceeds 2% of the total number of passengers/crew members on board.

However if the number exceeds 3%, it is labeled as an outbreak if it meets the following criteria:

  • Fall within the purview of the VSP (Vessel Sanitation Program)
  • Voyages from 3-21 days in length
  • 100 or more passengers
  • Cruise ships in which 3% or more of passengers or crew reported symptoms of diarrheal disease to the ships medical staff during the voyage.

A list of outbreaks on cruise ships since 1994 can be found on the CDC’s website.

Illnesses like norovirus can spread quickly in any place where there are a lot of people confined to a small space.  This includes dorm rooms, day cares,  hospitals, and schools.

The best way to protect yourself is to practice proper hand hygiene.  While alcohol based hand sanitizers can used in addition to hand washing, they should never be a substitute.

As they sing on Norwegian cruise ships, the best way to keep yourself healthy is “Washy Washy”.

  1. Keep in mind a ship can have norovirus on board and it is still not considered an outbreak per se. Celebrity Infinity had several sailings with this issue earlier this year. I was on one sailing where cleaning precautions were in place. Celebrity did a good job containing it and by the end of the cruise the restrictions have been lifted. At the same time I totally agree that they should stop calling this a cruise ship disease. It happens everywhere there are large groups of people together
