A 24-hour French lockdown imposed on a cruise ship struck by a norovirus outbreak has been lifted, allowing the 1,701 passengers and crew to begin disembarking in Bordeaux. French authorities gave the all-clear on Wednesday afternoon, permitting asymptomatic individuals to leave the vessel while those who had fallen ill were ordered to remain on board in isolation.
The lockdown was triggered on Tuesday when the Ambassador Cruise Line vessel Ambition docked in Bordeaux with a suspected outbreak of viral gastroenteritis. Local authorities confined all 1,187 passengers and 514 crew members to the ship as health officials investigated. Samples taken from those reporting symptoms were sent to Bordeaux University Hospital for testing, which confirmed the presence of norovirus.
What is norovirus?
Norovirus is a highly contagious form of gastroenteritis that causes vomiting and diarrhoea. It spreads rapidly through contaminated food or water, person-to-person contact, or by touching infected surfaces. Cruise ships, with their close-quarters accommodation and shared dining and entertainment spaces, are particularly vulnerable to outbreaks. Symptoms typically appear 12 to 48 hours after exposure and can last between one and three days, although individuals can remain contagious for up to two weeks after their symptoms subside. Dehydration is a potential complication, especially for vulnerable groups such as the elderly – a demographic that matches the Ambition‘s typical passenger profile, as Ambassador Cruise Line targets travellers over 50. The U.S. Centers for Disease Control and Prevention recorded 23 gastrointestinal outbreaks on cruise ships in 2025, the highest number in more than a decade, with the majority caused by norovirus. Just a week before this incident, more than 140 passengers and 15 crew members were affected by norovirus on the Caribbean Princess.
Outbreak and fatality details
By Wednesday morning, Ambassador Cruise Line confirmed that 48 passengers and one crew member had active cases of gastrointestinal illness, while other reports indicated around 80 people had developed symptoms. The outbreak appears to have escalated after the ship called at Liverpool on 9 May, following its departure from Belfast on 8 May. The vessel was on a 14-night “Delights of Western France & Spain Explorer” sailing. The captain alerted French authorities on Tuesday evening as the number of cases rose.
During the voyage, a 92-year-old British man died on board. French health authorities initially suspected his death might be linked to the norovirus outbreak, but later stated that it appeared to be unrelated. Ambassador Cruise Line said the guest had not reported any symptoms of gastrointestinal illness, and his death was attributed to a heart attack, pending a coroner’s report. The company expressed condolences to his family.
One passenger, Seos Guilidhe, 52, from Belfast, told news agency AFP that he was “playing bingo” during the lockdown and described the atmosphere as “not as bad as it was during Covid”, adding that people were “going about as normal”.
Cruise line response
Essex-based Ambassador Cruise Line said in a statement that it takes any illnesses aboard its fleet “extremely seriously”. Enhanced sanitation and prevention protocols were implemented immediately across the ship following the initial reports of illness. These measures included increased cleaning and disinfection in public areas, assisted service in selected dining venues, and ongoing guidance to passengers on hand hygiene, including regular hand washing, use of hand sanitisers, and prompt reporting of symptoms to the onboard medical team. The company also offered free medical consultations for any gastrointestinal symptoms.
A spokesman for the cruise line explicitly dismissed any connection between the norovirus outbreak on the Ambition and the hantavirus outbreak on the MV Hondius in April 2026, which involved the Andes virus and resulted in multiple deaths and hospitalisations. French ports, including Bordeaux, have established protocols for managing public health events on vessels in line with international health regulations, including health declarations and collaboration between ship medical teams and local authorities.
The Ambition, a Mistral-class cruise ship built in 1999 with a gross tonnage of 48,123 and accommodation for up to 1,200 passengers across 680 cabins and 13 decks, was extensively refitted in 2023. It was due to continue its itinerary to Spain before returning to Liverpool on 22 May. Ambassador Cruise Line has said it plans to increase its fleet size in the coming years.
