ORLANDO, Fla. — The CDC is investigating an outbreak of a stomach bug aboard a Disney Wonder cruise ship.

The Centers for Disease Control and Prevention says more than 130 people reported falling ill.

The ship had almost 2,700 passengers and almost 1,000 crew members. It left Miami last Wednesday and returned Sunday after going to the Bahamas.

The Orlando Sentinel reports that as of Monday, the number of those who fell ill climbed to 145 people, including 131 passengers and 14 crew members.

A spokeswoman says Disney Cruise Line implemented added sanitation measures such as continuous cleaning of handrails. Self-service stations at buffets and ice cream stations also were discontinued to limit passenger contact with food.

The ill passengers were confined to their rooms for 24 hours, and cruise activities weren’t affected. The primary symptom was vomiting.

The last time a Disney ship had a significant illness outbreak was in 2002.
