Iona Norovirus Outbreak 2025: Suspected GI Illness Disrupts Northern Europe Cruise

On 20 February 2025, P&O Cruises' vessel Iona reported a suspected norovirus outbreak during a 7-day roundtrip voyage from Southampton, UK. The ship was sailing off the coast of Belgium en route back to England when multiple passengers reported gastrointestinal symptoms including vomiting. Fewer than 1% of passengers were affected; no fatalities were reported.

P&O Cruises immediately implemented enhanced sanitation protocols and notified public health authorities. The vessel continued its voyage while managing the outbreak through isolation of affected individuals, increased cleaning of high-touch areas, and distribution of hand sanitizers throughout the ship.

Following confirmation of suspected norovirus cases on 20 February 2025, the ship's Captain addressed all passengers and crew. Enhanced sanitation measures were immediately deployed, including continuous disinfection of communal areas, isolation of symptomatic individuals in their staterooms, and restricted access to certain facilities. The onboard medical center operated around the clock to provide care. P&O Cruises assured affected travelers that full refunds would be provided for any missed shore excursions.
