Sickness Outbreak Hits French Cruise—But It’s Not Hantavirus

Topline

French authorities will allow a cruise ship with dozens of sick patients to continue its journey this week after initially locking down the boat in Bordeaux in efforts to contain a norovirus outbreak that has caused nearly 50 people to come down with the highly contagious stomach bug.

Key Facts

The ship Ambition of the Ambassador Cruise Line, a British operator, was sailing from the UK to Spain and France when four dozen patients and a crew member started exhibiting symptoms of norovirus, a common gastrointestinal virus that causes vomiting, diarrhea, fever and body aches.

The ship informed French health authorities of the situation before its scheduled stop in Bordeaux Tuesday, and officials ordered everyone to stay aboard the ship.

The lockdown was lifted late Wednesday and those passengers without symptoms who wished to disembark were allowed to leave the ship, though how many actually did remains unclear.

The ship, which has 1,701 people onboard, has also been authorized to continue its journey to Spain, though operators have not said when it will set sail.

One person reportedly died this week aboard the Ambition—the ship with the norovirus outbreak—but the 92-year-old man died of a heart attack unrelated to the virus.

French authorities have been clear there is no link between the norovirus outbreak on the Ambassador cruiseliner and the deadly hantavirus outbreak on a Dutch vessel that has passengers quarantining all over the world, including 18 in the United States.

Big Number

23. That’s how many outbreaks of gastrointestinal viruses occurred on cruise ships last year, according to the Centers for Disease Control and Prevention, most of which were caused by norovirus. There have been four so far this year, two caused by norovirus and two by E. coli.

Why Are Gastrointestinal Illnesses So Common On Cruise Ships?

The close proximity of passengers moving from restaurant to theater to pool deck and back again on a cruise ship allows germs to move through the ship extremely quickly. A majority of a cruise ship’s most popular amenities are indoors, and studies into cruise ship air quality have shown that illness can spread more easily in crowded, enclosed spaces like small cabins and restaurants. Some cruiseliners are also disproportionately popular with older people, who may be more seriously impacted by otherwise innocuous diseases like norovirus, and there’s relatively limited medical care available at sea. The CDC recommends cruisers wash their hands often, get plenty of rest, drink a lot of water and move quickly to report any symptoms of illness to help limit the spread of disease on board.
