CDC investigating after 97 fall sick on Disney cruise ship

ORLANDO, Fla. -- The CDC is investigating an outbreak of a stomach bug aboard the Disney Wonder cruise ship last week.

The Centers for Disease Control and Prevention says that 92 passengers and 5 crew members 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.

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.

"Our primary focus was on taking care of our guests and crew. We have a comprehensive plan that outlines protocols for managing this kind of situation and closely follow CDC guidelines for preventing the spread of common stomach-related illnesses," a Disney spokesperson said to CBS affiliate WKMG.

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.
