A British cruise ship, Ambition, faces a gastrointestinal illness outbreak. Over 1,700 passengers and crew are confined to the vessel in Bordeaux, France. French authorities have suspended disembarkation. The outbreak is not linked to a hantavirus scare on another ship. Affected passengers are receiving medical attention on board. Investigations are underway to determine the cause.

A hantavirus outbreak is one of the latest health crises tied to cruise ships, but experts say travelers don't have new cause for concern.
