Norovirus outbreaks most often makes headlines when they happen on cruise ships, but these only account for about 1% of all reported outbreaks, according to a report by the Centers for Disease Control and Prevention (CDC).

About 20 million people get sick from norovirus each year, according to the CDC Vital Signs report “Preventing Norovirus Outbreaks.”

In norovirus outbreaks for which investigators reported the source was food contamination, 70% are caused by infected food workers, CDC reported.

Of outbreaks caused by food workers, 54% involve touching ready-to-eat foods (i.e., food that is ready to be served without additional preparation, such as washed raw fruits and vegetables, baked goods or items that have already been cooked) with bare hands.

According to the CDC, observations of food service workers have shown that they practice proper hand washing only one out of four times. The CDC recommends that workers “wash hands carefully and often with soap and warm water for at least 20 seconds, especially after using the restroom.”

“Norovirus often gets attention for outbreaks on cruise ships, but those account for only about 1% of all reported norovirus outbreaks,” the report said.

“Norovirus is very contagious, and outbreaks can occur anywhere people gather or food is served.”

Caribbean Princess cutting cruise short due to fog and illness

Princess Cruises has been forced to cut short the current voyage onboard Caribbean Princess because of impending weather forecasts and a suspected outbreak of norovirus.

The vessel is scheduled to return to US waters today, one day earlier than had been intended in the itinerary, because of a heavy build up of dense fog that is expected to descend along the US coast tomorrow and for most of the weekend.

It will also require extra time for sanitisation under the watchful eye of the US Centers for Disease Control and Prevention, after passengers reported symptoms of the vomiting bug to the ship’s medical bay. According to reports, five passengers are sick with nausea and diarrhoea at present, however some 165 passengers and 11 crew are believed to have fallen ill during the course of the trip.

That represents five per cent of the 3,104 guests aboard Caribbean Princess and less than one per cent of the 1,148 staff members, which is someway short of the eye-watering number of sick reported aboard Royal Caribbean’s Explorer of the Seas this week, when more than 20 per cent of the 3,071 passengers reported with symptoms.

However, this represents the third confirmed outbreak of norovirus already this year. Last year by way of comparison, there were nine outbreaks in total. In order to stay on track with its accelerated timeline, the ship, which has been sailing since January 25th, was forced to skip a planned call at the port of Belize.

Princess said in a statement: “Because of the increased sensitivity surrounding Norovirus by both cruise lines and the CDC in this winter season, we notified the CDC who will be boarding on Friday to ensure all appropriate measures are followed for an extensive sanitation of the ship prior to the next cruise.”

Passengers will be provided with overnight accommodation in local hotels once the ship arrives in port, as well as a future cruise credit worth 20 per cent of their fare and a one-day allowance to put towards meals and other costs.

Royal Caribbean’s Explorer of the Seas returned to its home port in Bayonne, N.J., on Wednesday afternoon following a widespread outbreak of gastrointestinal illness on the 3,000-passenger ship.

The U.S. Centers for Disease Control reported that 629 passengers, more than 20% of the passengers onboard, were affected by the illness over the course of the cruise. Also, 54 crew members were reported ill.

The last time a cruise ship had as many sick people was in 2006, when 536 passengers and 143 crew members from the Carnival Liberty were reported ill, according to CDC records.

Royal Caribbean shortened the 10-day cruise to eight days to allow for extra sanitation measures before the next cruise on Friday.

“Guests scheduled for the next cruise on Explorer of the Seas can be confident that all possible measures will have been taken to prevent further problems,” a Royal Caribbean statement said.

Royal Caribbean said it plans a thorough sanitizing of the entire ship.

Officials from the U.S. Centers for Disease Control said they won’t know if it was a norovirus outbreak until later this week.

Passengers on the stricken cruise will receive a 50% refund of their cruise fare and a 50% future cruise credit.

Guests who had to be confined to staterooms will be credited with one future cruise day for each day of confinement.

Royal Caribbean said it will also reimburse airline change fees and hotel accommodations for guests whose travel home was inconvenienced by the change of travel plans.
